Beam Steering Optic Mount, Fixed Periscope, Top

The BSC-FMB is the same beam steering mount used on the BSD-F, Fixed Periscope. It incorporates a 45-degree mirror holder which is held captive to the post mount so that it will not fall out during manual rotation adjustment. The BSC-FMB can be used to create custom height versions of the standard BSD-F, or can be used for basic vertical beam folding.
