Fiber Collimators and Focusers


Brimrose offers a complete line of high performance collimators and focusers designed to collimate or focus light exiting from a fiber to a specified beam diameter or spot size. By utilizing diffraction limited lenses, the spot size of a few microns can be achieved.

Brimrose designs and manufactures matched pairs of collimator and focuser to couple light in and out of the desired devices.

The Brimrose high performance fiber collimator is a fiber optic device that has very small insertion loss, excellent return loss, high polarization extinction ratio, small beam divergence, etc.
