Our optical lens manufacturing solutions
Custom lens solutions for photonics applications, from sub-milimetre mircolenses for fiber optics to 500 mm diameter astronomy lenses, we manufacture lens to your design.
Our offer ranges from manually polished unique lens prototype to high-volumes moulded lenses.
All the optical lenses that we provide can be supplied with a specific anti-reflective thin layers coatings.
Lens manufacturing capabilities
Spherical lenses
Spherical lenses can be manufactured using different processes:
- Molded and polished (for high volumes)
- Mechanical grinding and polishing
- NC grinding and polishing (lenses requiring high surface quality)
Different shapes are available:
- Plano-convex lens
- Plano-concave lens
- Bi-convex lens
- Bi-concave lens
- Aspheric lens
- Cylindrical lens
- Toroid lens
