2

Samples & spec lock

Stock samples for field testing, badge and packaging samples for the branding check. Magnification, coatings, reticle, mode set and accessories locked in writing.

3

Production & QC

Milestones at grinding, coating, assembly and final inspection. Waterproof and collimation checks per unit on sealed models; verification data available per program.

4

Shipment & after-sales

Compliant export routing per destination (laser class, battery, labeling), warranty support and spare parts behind every category we ship.

Frequently Asked Questions

Are you a factory or a trading company?

A factory. Optical grinding, polishing and coating lines run in-house; verification runs on ZYGO and VECCO interferometers and Shimadzu spectrophotometers. Over 5,000 distinct lens types have come off those lines in more than a decade — the consumer instrument brand sits on top of that component factory.

What is the minimum order for private-label optics?

Existing platforms take modest MOQs with badge, engraving and packaging customization. Fully custom housings mean tooling and a higher commitment, quoted per program. Stock samples are available before you commit to anything.

Can you manufacture to our drawings for optical components?

Yes — that is the oldest line in the company. Windows, mirrors, lenses, prisms and filters to customer drawings, ISO9001-controlled, with interferometric and spectrophotometric verification data available per lot.

Do night vision and thermal products need export licenses?

Most destinations regulate them. We support buyers with classification paperwork and route shipments through compliant channels — plan licensing before the first purchase order, not after.

Where are you based?

Offices in Beijing (Changping) and Chengdu (Jinjiang), with the production base running grinding, coating and assembly lines. Video tours of the lines are available on a call.
