About Shunzhida
A precision optics manufacturer in Wuhan, China — your one-stop partner from drawing to volume production.
Wuhan Shunzhida Electronic Technology Co., Ltd. is a precision optics manufacturer based in Wuhan, China. We focus on three core sectors — optical component fabrication, optical systems manufacturing and optical process services — delivering a true one-stop path from drawing to volume production.
Founded in 2024, we operate a roughly 2,000 m² standardized production facility in Wuhan under temperature- and humidity-controlled conditions (22 ± 2 ℃), backed by an experienced optical engineering team. Three signature lines — precision lens fabrication, spectrometer system manufacturing and optical coating — carry equal weight and reinforce each other, achieving in-house closed-loop integration from optical components to complete systems.
The precision lens fabrication line covers generating, fine grinding, multi-axis polishing (surface figure down to λ/10), edging and cleaning through to inspection, working with N-BK7, fused silica, calcium fluoride, sapphire, zinc selenide, germanium and silicon to produce spherical, planar and prism optics; the spectrometer system build line, based on our own core optics, runs from optical design and opto-mechatronic-thermal integration to calibration and turnkey delivery, supporting OEM/ODM; the optical coating line uses electron-beam evaporation and IBS to produce AR, HR, filter and metal films.
We accept orders from a single piece and support prototyping (lead time 7–15 working days), serving both small-batch custom work for research and universities and volume delivery for industrial customers, with OEM/ODM available; our products and process services are applied across laser equipment, bio-medical, optical communications, R&D and universities, semiconductor inspection and consumer electronics.
Light connects industries — Wuhan Shunzhida Electronic Technology Co., Ltd. looks forward to becoming your trusted optics manufacturing partner.
Signature Production Lines
From core optical components to complete optical systems — all three signature lines run in-house, and every shipment leaves with an inspection report.
Shunzhida is built around vertical integration, operating a standardized production facility of roughly 2,000 m² covering cold working, coating, inspection and system integration, managed under temperature- and humidity-controlled conditions (22 ± 2 ℃) for batch-to-batch consistency.

Our Journey
Steady progress since foundation — from drawings and prototypes to repeatable volume delivery.
Company founded, first production line set up
The company was founded, the team was formed and a cold-working line was established — generating, fine grinding and polishing — taking on made-to-drawing custom work in standard materials such as N-BK7 and fused silica.
Inspection added, coating capability completed
Interferometric surface-figure testing was introduced and built into outgoing inspection, while conventional coatings such as broadband AR were brought in-house — supporting small-batch orders from universities and research labs.
End-to-end flow, ready for volume
A continuous flow was established across drawing review, fabrication, coating, inspection and assembly, covering diameters from Φ3 to 200 mm and extending to materials such as CaF2, ZnSe, germanium and silicon — still with a one-piece minimum.
