Capabilities
We'll start with raw materials used for the making of optical lenses. See our list of materials.
Our engineers can customize different optics to meet your specifications.
After designing, the manufacturing and production start. See our production equipment.
We are also able to do various coating for your lenses to meet your technical needs.
The lenses are assembled into modules for actual applications.
We always inspect our products to ensure consistent quality. See our metrology.
Not limited to module assembly, we also prototype systems.
From raw materials to system integration, we provide a total solution for your photonics need.
