LS-10 Series

Laser Safety Beam Shutters & Beam Dumps
The LS- range of laser beam shutters are combined shutters and beam dumps designed to be driven by a safety control system such as the Lasermet’s Interlock® controller for use as a means of shutting down the laser beam automatically during unauthorised access, or manually when the beam is not required. They can also be used as stand-alone laser shutters for manual or remote switching of the laser beam. 
  • Gravity-operated for fail safe control
  • Combined shutter and laser beam dump for added safety
  • Compatible with interlocked safety control systems
  • Safety latch prevents accidental laser beam switch on
  • Remote switching option
  • Available as OEM product

LS-10 and LS-100 Beam Shutters & Beam Dumps

The LS-10-12 and LS-100-12 shutters are designed to absorb 100% of the laser beam power, eliminating the need for an additional beam dump and avoiding hazardous reflections. The laser beam is converted into heat and emitted from the shutter case.

These shutters are compatible with lasers up to the maximum average power specified below.

The LS-10-12 can handle up to 20W of average power.

  • The LS-100-12 is fan-cooled and can handle up to 200W average power.
The LS-100-12 has been discontinued. This page only remains for reference.

Unless power is supplied, the shutters will not open. When power is applied, a yellow LED illuminates to indicate that power is available. When the shutter is fully closed, a green LED will illuminate. The green button must be pressed to open the shutter. When the shutter is fully open, the green LED will turn off and an orange LED will illuminate. By pressing the red button or turning off the power, the shutter can be closed.

Opening any laboratory door without using the override will result in the shutter closing, preventing unprotected individuals from being exposed to laser radiation. The shutter is fail-safe and gravity-operated, so when power fails, the shutter will close without the use of springs or any other device.


Low current consumption is the result of intelligent design. This increases the number of shutters that can be powered by the same power supply while also keeping the shutter cool enough to function as a beam dump when closed.

The shutters LS-10-12 and LS-100-12 operate on 12 VDC. If your power supply is 18-24 VDC or similar, Lasermet offers the LS voltage converter (Part no. LS-VC-24.12), which allows for operation from 15 to 35 VDC.


The Remote Switching Station (Part No. LS-RS) can be used to open and close the shutter remotely when the LS-10-12 and LS-100-12 laser shutters are used in an enclosure and the buttons cannot be accessed, or for other remote switching requirements.

Alternatively, the LS-10-12 and LS-100-12 laser shutters can be shifted into’switch bypass mode’ by modifying some internal links on the PCB inside the shutter. When the power is turned on, the shutter opens immediately and closes when the power is turned off.


An optional Interlock® board (LS-10-IB) can be installed, providing two volt-free contacts, one normally open and one normally closed, that can be used to Interlock® another device to the shutter status. These contacts have a 2A and 30 VDC rating.


The LS-10-12 has a single M6 thread in the base and can be mounted to a breadboard by use of an optical pin.

The LS-100-12 has four M6 mounting threads in the base.  It can be mounted on a breadboard at any angle, by use of the mounting plate pack LS-100-MP and metric (LS-100-MAS) or imperial (LS-100-IAS) mounting screws.
