SH05 Beam Shutter

The SH05 is a rotary, electro-mechanical actuator to provide sub-millisecond
shutter operation. In general operation, the shutter remains in a closed position
and then opens with a pulse control signal. As long as the control voltage to the
shutter remains high, the shutter will stay open; however, if the voltage suddenly
decreases, the shutter will close, providing inherent "fail-safe" operation. An optical
sensor, which detects the shutter blade's position within the housing, confirms the
state of the shutter position, making it ideal in applications where a laser safety
lockout is required. The rate at which the device is opened can be controlled. The
unit has a 0.50-inch aperture opening and is compatible with the Thorlabs SM05
mounting system.
The input aperture of the SH05 is threaded with Thorlabs' SM05 (0.535"-40) thread
to interface easily with all of our SM05 lens tubes. The SH05 comes with 8-32
tapped holes for mounting to our imperial Ø1/2" posts. The SH05/M comes with
M4 tapped holes for mounting to our metric Ø1/2" posts. All shutters come with a
10' cable to connect the shutter directly to the SC10 Controller (sold separately).
