CeramOptec’s® collimators and focusing devices (beam-shaping) for optical systems are ideal for UV to NIR applications, and can be used with most assemblies or bundles. Our unique design is available in three convenient sizes that can accommodate nearly any size fiber: Small — for fibers up to 400 microns; Medium — for fibers up to 800 microns; and Large — for larger fibers. Our Medium and Large collimators and focusing devices are compatible with each other.
