Explore 28 top manufacturers and suppliers of Fiber Optic Collimators in our comprehensive photonics buyers' guide. Its primary function is to convert the expanding cone of light from a fiber into a beam with a nominally constant diameter (collimated beam), or vice. Thorlabs offers a variety of fiber collimation and coupling solutions. FiberPorts can be used to provide a stable platform for coupling light into and out of FC/PC, FC/APC, or SMA terminated fiber with five or six directional adjustments. The beam's performance is governed by two primary parameters: 1) Beam Divergence. ©2025 Newport Corporation. The lenses are diffraction limited, so they can achieve spot sizes down to a few microns.
