    Local transport

    Get around the city with these convenient transport options.

    Airport Express Line (metro, Orange Line)

    Estimated costINR 30-80 single metro journey
    Best forIndira Gandhi International (DEL) to Bharat Mandapam, Hall 1, Pragati Maidan

    Fastest rail option into the city centre, roughly 20 minutes to New Delhi station before the metro change. Confirm airport station access hours and luggage rules on the Delhi Metro or Airport Express site before relying on it for a late arrival.

    Delhi Metro Blue Line

    Estimated costINR 30-80 single metro journey
    Best forNew Delhi or Rajiv Chowk to Pragati Maidan station, walk to Bharat Mandapam Hall 1

    Pragati Maidan station on the Blue Line puts the fairground within walking distance of the halls. Buy a smart card or use the QR ticket option to avoid queues at peak hours.

    pre-paid taxi

    Estimated costApprox. INR 600-900 per car, one way; confirm the counter slip fare
    Best forDEL Terminal 3 pre-paid taxi counter to Bharat Mandapam, Pragati Maidan

    Use the official pre-paid counter inside the terminal rather than accepting unsolicited offers in the arrivals hall. Journey time is roughly 45-60 minutes off-peak but can double in rush hour or winter fog.

    ride-hail app cab (Ola / Uber)

    Estimated costApprox. INR 450-800 from DEL to the venue off-peak; higher with surge or during peak hours
    Best forDEL to Pragati Maidan, or hotel in Mahipalpur or central Delhi to the venue

    App cabs are the most flexible option for exhibitors moving between hotels and the fairground. Pick-up zones at DEL are designated; follow the app instructions and keep the drop point at the named Pragati Maidan gate.

    auto-rickshaw

    Estimated costApprox. INR 50-150 per short trip; agree the fare or insist on the meter
    Best forShort hops between Pragati Maidan metro station, nearby hotels and the fairground gates

    Useful for the last kilometre around the Pragati Maidan complex, but not practical for airport runs with luggage. Carry small denomination notes and confirm the fare before starting.

    parking (private vehicle)

    Estimated costApprox. INR 100-300 per day for venue parking; confirm the current charge at the gate
    Best forBharat Mandapam / Pragati Maidan complex parking, Hall 1 access

    Parking capacity tightens sharply during a trade week and gate allocations can change by hall. Arrive before the morning peak, keep the parking slip, and check the designated gate for Hall 1 with the organiser or venue.

    Weather

    January is New Delhi's coldest month. Expect daytime highs near 18-22 C and night-time lows around 5-8 C, with occasional cold waves pushing the minimum lower. Dense morning fog is common and can delay flights and road transfers, and winter air quality is typically poor, so allow buffer time on arrival day and carry a mask if you are sensitive to particulates. Rainfall is low, but a western disturbance can bring a short spell of light rain - take a compact umbrella and a warm layer for evening transfers.

    Plan for the climate

    Check temperatures and pack accordingly

    Venue connectivity

    Airtel, Jio and Vi operate 4G and 5G networks across New Delhi, with good coverage at Pragati Maidan and the Mahipalpur and Aerocity hotel belts. A tourist SIM needs your passport and a photograph; eSIM plans can be activated before departure and are usually the faster option. Wi-Fi is generally offered in hotels, and Bharat Mandapam provides connectivity for exhibitors through venue service orders, so check the order form if you need dedicated bandwidth for instrument demos. India runs on 230V at 50Hz with type C, D and M sockets, so bring a universal adapter, and note that UPI QR payment is widespread but not always linkable to foreign cards.

    Cultural notes

    Useful information to help you have a smooth and respectful visit.

    Business language and greetings

    English is the working language of most Indian trade fairs and stands, so technical discussions about lenses, coatings and instruments usually run in English. A handshake is common in business settings; a folded-hands namaste is a respectful alternative and is often offered first by older counterparts. Use titles and surnames until invited to be informal.

    Meeting rhythm and business cards

    Expect a short opening conversation before commercial detail, and offer and receive business cards with the right hand. Stand discussions can be interrupted and resumed, so confirm follow-up by email with a written summary of specifications, quantities and lead times rather than relying on a verbal understanding at the booth.

    Dress and venue etiquette

    Business casual to formal is appropriate for Bharat Mandapam: collared shirts and trousers or suits for men, business dress or trouser suits for women. Halls are air-conditioned but transfers are outdoors, so a light jacket works for both. Ask before photographing a stand, product display or a person.

    Food, dietary and alcohol

    Vegetarian food is widely available and many of your counterparts may not drink alcohol. Lunch is often late by European standards, and stand meetings frequently run across the midday block. If you have specific dietary needs, mention them when arranging a business meal; hotels in the Mahipalpur and central Delhi belts cater to most requirements.

    Payments and tipping

    The currency is the Indian rupee (INR). Cards and UPI QR payments cover hotels, restaurants and larger retailers, but keep small notes for auto-rickshaws and site porters. Tipping is not mandatory; rounding up a taxi fare or leaving a modest amount in restaurants is normal practice, and hotel and airport porters typically expect a small note per bag.

    Security, air quality and daily logistics

    Entry to the Pragati Maidan complex involves bag screening, so allow extra time on the first morning and keep ID with your badge. January air quality in Delhi is often poor and mornings can be foggy; a mask and a planned indoor route between halls help. Keep a charger and a bottle of sealed water with you, and avoid scheduling tight back-to-back airport transfers during peak traffic.

    Practical guides

    Visitor & Exhibitor Essentials

    Everything needed to arrive prepared, navigate the event, and make the visit productive.

    Flights

    Destination: DEL

    No usable inbound airfare to Delhi was captured for this edition: the Google Travel mission for the 9-11 January 2027 window returned US domestic city pairs rather than the requested origins into DEL, so no fare band is published here. Book on live inventory into Indira Gandhi International (DEL), which handles international arrivals at Terminal 3, and compare a one-stop Gulf or Asian hub connection against direct services from your region. Two timing points matter for this event: January morning fog in Delhi is a regular cause of delays, so avoid a tight same-morning connection into a first-day meeting; and the return leg should allow slack after the closing day if you are dismantling a stand. Confirm the final published show dates on opticsfair.in before ticketing, and treat any fare shown elsewhere as indicative until you see it on the airline or a live fare search.

    Transport

    Get to the venue and around the city with these options.

    Airport → venue: Primary gateways: Indira Gandhi International (DEL). Allow road or rail time to Bharat Mandapam, Hall 1, Pragati Maidan; on-site parking is usually available at major exhibition venues.

    Hotel → venue: Precinct hotels near Bharat Mandapam, Hall 1, Pragati Maidan: New Delhi (Mahipalpur / airport corridor): Hotel Belwood By Signature Stayz; Mahipalpur, New Delhi: Hotel Premier Inn Hotel in Mahipalpur Delhi Ncr; New Delhi: Hotel The Vanson Pride Suites.

    Ride-hail: Ola and Uber are the main app-cab operators in New Delhi, with BluSmart running an electric fleet that some corporate travellers prefer. Coverage is good around Pragati Maidan and the Mahipalpur and Aerocity hotel belt, but surge pricing appears during the morning and evening peaks and after large events close. At Indira Gandhi International (DEL) use the designated app-cab pick-up zone rather than accepting offers inside the arrivals hall, and set the drop point to the named Pragati Maidan gate serving Hall 1 so the driver does not circle the complex. Approximate off-peak fares from DEL to the venue sit in the INR 450-800 band - confirm the app estimate before you book and keep small cash as a backup.

    Public transit: The Delhi Metro is the most predictable way to reach Bharat Mandapam: Pragati Maidan station on the Blue Line is within walking distance of the halls, with journeys priced roughly INR 10-60 depending on distance - confirm live fares. From the airport, the Airport Express Line (Orange Line) runs to New Delhi station in about 20 minutes for roughly INR 60-110, then connects to the Blue Line towards Pragati Maidan. DTC and cluster buses also serve the Pragati Maidan area at low fares but are slower and less convenient with luggage. A metro smart card or QR ticket saves queueing at busy stations, and services are frequent from early morning to late evening - check the last train time if your flight lands late.

    Parking: Bharat Mandapam sits inside the Pragati Maidan complex, which has managed parking with controlled gate access for each hall. Capacity fills quickly during a trade week, and the gate allocated to Hall 1 can change between build-up and show days, so confirm the designated entry with the organiser or venue before driving. Approximate daily parking charges sit in the INR 100-300 band - confirm the current rate at the gate - and peak-hour queues at the complex entry can cost more time than the metro. Exhibitors with freight or instrument deliveries should use the official vehicle and loading window rather than the public car park.

    Weather

    Plan and pack for the event climate.

    Month: January (winter)

    Temperature: Approx. 5-22 C across the show period: daytime highs near 18-22 C and night-time lows around 5-8 C, with occasional colder spells during a cold wave. These are climatological bands, not a forecast - check the live forecast in the week before travel.

    Seasonality: January sits in Delhi's dry winter, with low average rainfall, but a passing western disturbance can bring a short spell of light rain and thickens the fog. Dense morning fog is the main seasonal risk for flights and road transfers, and winter air quality stays poor through most of the month. Carry a compact umbrella and keep transfer buffers generous on arrival day.

    Packing: Pack layers rather than one heavy coat: a warm jacket or overcoat for early mornings and evening transfers, sweaters or a mid-layer for air-conditioned halls, and business casual for stand meetings. Add closed comfortable shoes for walking the halls, moisturiser and lip balm for dry winter air, and a mask if you are sensitive to Delhi's winter particulates. Bring a universal power adapter for 230V type C, D and M sockets, and keep a compact umbrella for an occasional western disturbance.

    FAQs & glossary

    Answers

    Frequently asked

    When and where does Optics Fair take place in New Delhi?
    Optics Fair is planned for January 2027 at Bharat Mandapam, Hall 1, Pragati Maidan, New Delhi. The travel and hotel planning used across this listing is anchored on a 9-11 January 2027 stay window; confirm the final published dates and hall allocation on opticsfair.in before you book flights or hotels.
    How do I register as a visitor for Optics Fair?
    Visitor registration is handled through the organiser website, opticsfair.in. Trade visitors normally complete an online form, receive a confirmation with a badge QR code, and collect the physical badge at the venue registration counter on arrival. Carry the same photo ID you registered with, plus a printed or saved copy of the confirmation, because Pragati Maidan entry includes a security check.
    Is Optics Fair open to trade visitors only?
    Optics Fair is structured as a business-to-business optics event, so the audience is optical retailers, lens laboratories, distributors, optometrists, eye-care chains and instrument or component buyers. If you are unsure whether your profile qualifies, or you want to bring a non-trade guest, ask the organiser before travelling - access policy is set by them, not by the venue.
    What product categories are on show at an optics fair in Delhi?
    Expect the floor to be organised around ophthalmic lenses and coatings, frames and sunglasses, contact lens and care products, optical instruments such as autorefractors, lensmeters, perimeters and edging or surfacing equipment, lab consumables, and the technical optics and photonics supply side including optical components, metrology and laser or imaging modules. Hall themes and the final exhibitor list should be checked on the organiser site closer to the edition.
    What is the fastest way from Indira Gandhi International Airport to Bharat Mandapam?
    Indira Gandhi International (DEL) sits roughly 15-18 km by road from Pragati Maidan. A pre-paid taxi or app cab takes about 45-60 minutes outside peak traffic and longer during the morning and evening rush. The rail option is the Airport Express Line to New Delhi station, then a change onto the Delhi Metro Blue Line towards Pragati Maidan station - allow 60-80 minutes door to door with luggage.
    Where should exhibitors and buyers stay in New Delhi?
    Two clusters work well. The Mahipalpur and Aerocity belt near DEL suits early flights and late arrivals, with budget-to-midscale rooms in the region of INR 1,900-6,200 per night in the captured 9-11 January 2027 search. Central Delhi and the Pragati Maidan side cut daily commuting but usually price higher during a trade week. Book a free-cancellation rate and reconfirm in December, since January is a busy convention period in the capital.
    What is the weather like in New Delhi in January?
    January is Delhi's coldest month, with daytime highs around 18-22 C and night-time lows near 5-8 C, occasionally lower during a cold wave. Mornings are often foggy, which can delay flights, and air quality is typically poor in winter. Bring layers, a jacket for the evening, and a mask if you are sensitive to particulates.
    Do I need a visa to attend Optics Fair in New Delhi?
    Most foreign nationals need a visa. India operates an e-Business Visa route for eligible nationalities that is applied for online before travel, alongside the regular business visa issued through Indian missions. Rules on validity, permitted stay and required documents differ by passport, so verify on the official Indian government visa portal and with your nearest Indian mission, and apply well before your departure date.
    Can I drive or park at Bharat Mandapam during the show?
    Bharat Mandapam has parking at the Pragati Maidan complex, but capacity tightens sharply during a trade week and gate access is controlled. Arrive early, follow the marshals, and confirm the current daily parking charge and the designated hall gate with the organiser or venue before you drive in. App cabs and the metro usually save time on show days.
    How do payments and connectivity work for a business trip to New Delhi?
    The currency is the Indian rupee (INR). Cards are widely accepted at hotels and larger restaurants, and UPI QR payments are common, though some foreign cards are not linked to UPI - carry a backup card and some cash. Airtel, Jio and Vi provide 4G or 5G coverage across the city; a tourist SIM needs your passport and a photograph, and eSIM plans can be activated before departure. India runs on 230V, 50Hz with type C, D and M sockets, so bring a universal adapter.
    What should exhibitors know about shipping optical equipment to the venue?
    Optical instruments, lasers and precision measuring equipment need advance freight planning: confirm the official freight contractor and delivery window with the organiser, and check temporary import or Carnet documentation with an Indian customs broker before dispatch. Book electrical load, rigging and any compressed-air supply through the venue order forms, and leave calibration time on site before the doors open.

    Glossary

    1
    Ophthalmic lens
    A lens fabricated to a prescription and worn in a frame or contact-lens format; at an optics fair it is usually specified by material (mineral glass, CR-39, polycarbonate, high-index), base curve, diameter and coating package rather than by brand alone.
    2
    Refractive index (n)
    The ratio of light speed in vacuum to light speed in the lens material; it drives how thin a lens can be for a given prescription. Values such as 1.50, 1.60, 1.67 and 1.74 are the standard talking points between lens suppliers and optical retailers.
    3
    Progressive addition lens (PAL)
    A single-vision-style lens with a continuously changing power that provides near, intermediate and distance zones without a visible line. Corridor length, fitting cross height and freeform design generation are the usual comparison points for buyers.
    4
    Freeform (digital) surfacing
    Computer-controlled lens generation that cuts a freeform surface to a patient's prescription and frame wrap data instead of using semi-finished moulds; a common differentiator for lens laboratories exhibiting on the show floor.
    5
    Anti-reflective (AR) coating
    A multi-layer vacuum coating stack that reduces surface reflections and increases light transmission. Suppliers typically quote number of layers, residual reflection colour, hydrophobic and oleophobic top coats, and scratch resistance test standards.
    6
    Aberration (spherical and chromatic)
    Image defects arising from lens geometry or material dispersion. Aspheric and atoric lens designs, and high Abbe number materials, are marketed as the corrective answer, so these terms recur across lens and instrument demonstrations.
    7
    Optical component (lens, prism, window, filter)
    A finished or semi-finished passive optical element supplied to equipment makers. Buyers compare substrate, dimensional tolerance, surface figure, and coating specification rather than consumer prescription parameters.
    8
    Optical metrology
    Measurement equipment and methods used to verify optical surfaces and systems, such as interferometers, profilometers, centration and power measurement stations, and transmission or reflectance spectrophotometers used to check coatings.
    9
    Photonics
    The engineering discipline covering generation, transmission, modulation and detection of light, spanning fibre optics, lasers, detectors and imaging modules. It is the technical umbrella under which optical components, instruments and lab systems are traded.
    10
    Optical laboratory finishing
    In-house or commercial lab operations covering lens edging, drilling, tinting, coating application and frame fitting. Finishing equipment and consumables are a distinct buying category from finished eyewear and instruments.
    11
    Abbe number
    A measure of a material's dispersion, where higher values mean less chromatic aberration. It is quoted alongside refractive index when retailers compare lens materials for high prescriptions.
    12
    Frame material and finish
    Frame specifications covering acetate, injection-moulded plastics, titanium, stainless steel, beta-titanium and monel, plus surface finishes and hinge construction. Optical buyers assess weight, adjustability and warranty terms at the stand.
