We help imaging, medical and photonics companies turn optical requirements into manufacturing solutions in China — from supplier qualification and custom development to build-to-print production and ongoing supplier management.
One commercial and technical interface from inquiry through delivery. No chasing factories, comparing quotes, or following up orders yourself.
Our research team supports technical assessment, feasibility review, and custom development when requirements go beyond standard products.
Suppliers are matched by technical capability, manufacturing capacity, order scale, and delivery conditions — and managed on an ongoing basis.
Sensor formats from 2/3″ to 59 mm, C / M58 / M72 mounts, distortion down to 0.01%.
Learn more →5–25 MP, 1/1.8″–1.2″ sensors, focal lengths 4–75 mm, low-distortion designs.
Learn more →Single-shot full-perimeter imaging for inner and outer wall inspection.
Learn more →Bi-telecentric lenses with collimated illumination (>95% uniformity).
Learn more →Sub-micron non-contact measurement, incl. multi-layer transparent thickness.

To most of our clients, OPD stands for what we do: Optical · Precision · Design. To optical engineers, it is also a familiar quantity — Optical Path Difference — the term at the heart of every wavefront and every interference pattern.
“We care about the difference, down to the wavelength.”
Optics for Your Needs. Precision for Your Vision.
