We provide a full family of Gaussian beam fiber-optic collimators for coupling light into and out of fibers. Through detailed design considerations and proprietary high-return loss technology, these collimators exhibit extremely low beam distortion, low loss, high return loss, and high reliability.
We have the capability to design and manufacture custom collimators to the specs of your choice. Beam diameter, working distance, fiber type, and wavelength can all be customized to fit your individual applications.
Standard wavelengths are 900-1100nm and 1520-1600nm. Customized designs in other wavelengths can be made per your requirements, from 400-2000 nanometers.
These collimators are available with variety of different single-mode fibers (SMF-28, PM980, PM13, PM15, LMA, and PLMA) and Multimode fibers and cabling options (bare fiber, Hytrel, Taflon , and PVDF tubes), providing the appropriate level of protection for the environment and operating temperature range.
