Collimator Micro Lens Fiber Optic Assemblies The collimating micro lens fiber optic assemblies are designed to offer either collimation of an emitted beam or focusing of a coupling beam. The assemblies can be customized with a variety of connector types and lens shapes to suit the customer's desired…

…divergent and asymmetric (elliptical) beam, optics are
used in the laser head to produce a collimated, elliptical beam. To reduce the complexity of downstream beam delivery
optics, each head has an adjustable output lens in order to enable smooth adjustment of the beam waist location.
--> Incoupling Optics Incoupling optics distribute laser energy into one or more process fibers. The optics can accept either a free space collimated beam or a feeding fiber from a fiber laser. It is possible to time-share or energy- share a laser between several work stations. Integrated control…

dovetail are lightly seated (minimal pressure applied)--the
SMA mount needs to be able to move relative to the dovetail
to peak coupling efficiency.
