Collimator Series
A collimator is an optical device that collimates a light beam into parallel light. We offer single-fiber, dual-fiber, multi-fiber, and polarization-maintaining fiber collimators, and can be housed in metal housings upon request.
Description
A collimator is an optical device that collimates a light beam into a parallel beam. We manufacture single-fiber, dual-fiber, multi-fiber, and polarization-maintaining fiber collimators, and can be housed in metal housings upon request.
Common fiber collimators are primarily composed of:
Fiber
Single-mode fiber (SMF), polarization-maintaining fiber (PMF), or multimode fiber (MMF);
One end connects to the external system, and the other end is secured to a lens.
Microlens
Spherical lens (spherical lens collimator)
GRIN lens (gradient index lens)
Flat lens or aspheric lens (for higher precision)
Casing/Housing
Encapsulates the fiber and lens, ensuring stability and mechanical strength.
A metal housing (stainless steel, Kovar, etc.) is typically used.
Gluing and Alignment Process
Use low-stress, low-shrinkage adhesive to secure the fiber and lens.
Ensure beam centering, angle, and position accuracy.
