Product Description

Hobbite® MircoLens(C-Lenses)

Hobbite Micro lenses (C-lens) are the basic optic componet in optical communication devices.  They are used to couple collimated beams and divergent beams, for example,coupling from fiber to fiber, source to fiber, or fiber to detector.

The advantages offered by C-lens include low insertion loss, wide working distance range and low cost.

Hobbite can provide various C-lenses as of the customer demands.  Pigtail and C-lens can be assembled into a collimator, which realizes many functions of optical signal processing in parallel light. Then the collimator is used for applications such as isolator, optical switches, attenuator and wavelength division multiplexers (WDM).
