Capabilities

Optical Materials

We'll start with raw materials used for the making of optical lenses. See our list of materials.

Optical Design

Our engineers can customize different optics to meet your specifications.

Optical Manufacturing

After designing, the manufacturing and production start. See our production equipment.

Optical Coating

We are also able to do various coating for your lenses to meet your technical needs.

Module Assembly

The lenses are assembled into modules for actual applications.

QA & QC

We always inspect our products to ensure consistent quality. See our metrology.

System Prototype

Not limited to module assembly, we also prototype systems.

System Integration

From raw materials to system integration, we provide a total solution for your photonics need.

Manufacturing Capabilities

We are able to produce the best diamond turned optics thanks to our 2 decades of experience and our sophisticated diamond turning technologies.
