Gimbal Beamsplitter Holders / BHAN
The frame of these mounts are narrow to accomodate a greater clear aperture at 45 degrees incident.
The transmitted beam diameter is just about he same as the reflected beam diameter.
Appropriate for beam branching optical systems or Michelson interferometers.
BHAN-S functions the same as MHAN.
