Collimators
Fiber collimators consist of an optical fiber tip precisely aligned to a collimating lens which is either a GRIN lens or a C-lens. It collimates beam from fiber, or couples collimated beams into fiber.
Feature
- Low insertion loss
- High return loss
- Good uniformity
- Epoxy free in optical path
- Compact size
Application
Isolators, Circulators, Optical Switches, WDM, Signal processing...
