To couple light both into and out of an optical fiber, it is essential to have a collimated light beam. With the help of an optical collimator, the divergence of the light beam can be significantly reduced. To meet this demand, LASER COMPONENTS developed its own collimator systems. These solutions are manufactured at the production facility in Olching and are currently available with six focal lengths, three housing assem-blies, and various coatings. Emphasis is primarily placed on single-mode fibers, silica fibers with an NA of 0.22, and hollow-core fibers. These collimators can be focused mechanically and are available for SMA and FC connector systems. Delivered including focusing tool.
