Full production Product specifications are stable. Delivery time is predictable.


Manual beam shutter is necessary to comply with CDRH laser safety requirements for lasers in Class 3B and Class 4. The shutter extends with a tube having the standard SM05 (Thorlabs compatible) internal thread. This tube can be used to assemble a beam expander, add polarization rotators, waveplates, filters, and other standard 1/2" optics.

The shutter can be centered with respect to the laser beam in two directions. First - by sliding the whole shutter assembly in the transversal heatsink recession and second - by using a setscrew to change the height of the shutter's aperture.

  • Can be used to assemble beam expander
  • Can be used to add polarization rotators, waveplates, filters
