Beam shutter
Thorlabs

The SH05 Beam Shutter utilizes 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 stays open, but as soon as the voltage goes low the shutter closes, providing inherent "fail-safe" operation. An optical sensor, which detects the shutter blade position in the housing, provides information that confirms the state of the shutter position. This makes it ideal in applications where a laser safety lockout is required. The rate at which the device is opened can be controlled.

The input aperture of the SH05 is threaded with Thorlabs SM05 (0.535"-40) thread to easily interface with all of our SM05 lens tubes. The SH05 is English and Metric System compatible and comes with a 10' cable to connect the shutter directly to the SC10 Controller.

Thorlabs offers two controllers for the SH05 which include an "interlock mode" incorporated into the control logic of the controller.
