Micro C-Lens & Ball Lens

1. C-Lens

These micro C-lens are specially designed for applications such as collimator, isolator, switch, collimator array and laser Assembly. Comparing to gradient index lens, C-lens has advantages including low cost, wide working distance range, low insertion loss especially in long working distance.

C-Lens Properties

Lens material : glass like
Transmission : >99%(900-1700nm)
Polarization preservation : 0.99
Max operating temp : 400°c
Hygroscopic susceptibility : no
Acid and Alkaline resistance : Excellent
Thermal expansion coefficient : <6x10E-6/°c
Power handing : >1w

C-Lens Applications

- Collimator
- Isolator
- Switch
- MEMS
- Collimator Array
- Laser Assembly
fiber optics lens
