Concept
The LS-10-12 is a laser beam shutter and beam dump designed specifically for safety applications. It
can, however, also be used for beam control (i.e. turning a laser beam on and off). When used for
safety applications the electrical power to the LS-10-12 must be supplied by an interlocked shutter
supply such as the Lasermet ICS-6. It will then provide fail safe interlocking of the laser beam to
protect persons entering the laser area from the laser beam hazard.
The LS-10-12 is designed as a combined shutter and beam dump and will not reflect the beam back
out of the shutter. Consequently, there is no requirement for an additional beam dump. When used
for safety interlocking the shutter input tube should be butted up against the laser to totally enclose
the beam and ensure that there is no accessible laser beam when the shutter is closed.
This beam shutter is gravity fed and not reliant upon springs, electrical power or any other drives or
devices for return to the safe mode.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which
can be connected to provide a complete laser interlock system. Full support, design and installation
is available from Lasermet, please contact us for any queries. Contact details are given at the end of
this manual.

Installation
Mount the LS-10-12 in front of the laser aperture with the ‘Beam input’ side facing the laser
aperture. For safety interlocking applications, if there is any space between the laser aperture and
the shutter input tube, metal tube must be used to enclose the beam. The shutter must be mounted
vertically with its face perpendicular to the laser beam. There is an M6 thread in the base for
mounting on an M6 optical stem.
