Fiber-Optic Collimators / Focusers
Brimrose offers a full range of high‑performance collimators and focusers that shape light from a fiber into a specified beam diameter or spot size. With diffraction‑limited lenses, we achieve micron‑scale optical control and engineer matched collimator–focuser pairs that efficiently couple light in and out of your system.
Our fiber collimators deliver stable, efficient optical output with minimal loss and tightly controlled beam quality, ensuring reliable light transfer for demanding optical applications.
Performance Capabilities
The fiber collimators and focusers’ performance capabilities are defined by their core optical functions and the application use cases they enable, with custom configurations available to support specialized optical testing requirements.
