A beam reverser module for an optical power amplifier of a laser arrangement comprises at least one reflecting surface for receiving an incoming laser beam propagating in a first direction and reflecting the incoming laser beam into a second direction different from the first direction, wherein the at least one reflecting surface is a highly reflecting surface of at least one mirror.

A fiber inspection system for inspecting optical-fiber endfaces of a multiple-fiber connector is provided that includes a housing structure, a mating interface fixed relative to the housing structure for interfacing with the multiple-fiber connector, and an imaging assembly. The imaging assembly is enclosed in the housing structure and defines an inspection plane and an image plane, at least a plurality of the optical-fiber endfaces being disposed on the inspection plane, to within a focusing range, when the multiple-fiber connector is mated to the mating interface. The imaging assembly also defines an imaging axis between an inspection point on the inspection plane and a detection point on the image plane, and includes an alignment module disposed between the inspection plane and the image plane and controllable to move the inspection point across the inspection plane for selectively inspecting one or more of the optical-fiber endfaces.

Optical element (1) comprising a first window (21) and a second window (22), wherein the first window (21) is connected to the second window (22) by an elastic membrane (41) such that the first window (21), the second window (22) and the membrane (41) enclose a deformable, sealed volume (42), which is filled with a fluid, wherein at least one first actuator (51) is arranged to tilt the first window (21) with respect to the second window (22) around a first tilting axis (81) in a first direction, wherein the first actuator (51) comprises a Shape Memory Alloy and has the shape of a wire.

An exemplary support structure for a planar faceplate includes ribs extending substantially perpendicular to a bottom surface of the planar faceplate. Spaced apart projections extend from the ribs towards the bottom surface of the planar faceplate and have distal ends that engage and are secured to the bottom surface. Each distal end defines an area with a numerical value that is less than the thickness of the planar faceplate measured in the same measurement units as the area to limit any stress formations induced in the planar faceplate due to thermal changes from reaching a top surface of the planar faceplate. Alternatively, the projections may be spaced apart mesas extending outward from a rigid material.
