Description

LS-200 Standard and LS-200SIL-24 Laser Shutters

The LS-200 Laser Safety Shutter is designed to prevent accidental exposure to potentially harmful laser beams. When the shutter is open the laser beam passes in clear air through the shutter. When closed, the shutter deflects the incoming laser beam out of a separate port to an appropriate beam dump which must be fitted.

The shutter uses a gravity close blade and force-disconnect proving contacts and is designed to form part of a high-integrity safety system. The equipment comprises of the LS-200 shutter with a power/communications cable and fixing nuts.

The shutter has a Ø50mm aperture.

SIL3 Dual-channel Version

A SIL3 dual version is also available which, when correctly wired with the Lasermet Interlock® Controller System can provide a safety Interlock® which meets Safety Integrity Level 3 to EN 61508 and ISO 13849-1 Performance Level ‘e’.

Compatible Beam Dumps

A Lasermet beam dump (sold separately) may be ordered with the shutter as a complete set. Users may wish to use a separate beam dump of higher capacity for use with a mirror blade and higher powered lasers.

Control Options

The shutter is usually controlled and powered by a Lasermet Interlock® controller when all safety interlocks have been closed. If the Interlock® is tripped out the shutter closes immediately. It cannot be opened until the Interlock® system is re-armed. There are three options in wiring the shutter.

Option 1

Arming the Interlock® system enables the operation of the shutter. The shutter can then be opened or closed using the buttons on top of the shutter.

Option 2

In addition to option 1, the shutter may be remotely opened or closed by external controls such as Lasermet’s Remote Shutter Switching units.

Option 3

Arming the Interlock® opens the shutter immediately. No need for manual controls.

Shutter Blade Information

Blade options include stainless steel, copper, ceramic, and coated glass. Cleanliness of the blade is important. A perfectly clean blade will successfully divert a beam. It is essential that the blade is kept clean to avoid excessive heat absorption as this can lead to ablation of stainless steel blades.

The standard LS-200 shutter using a stainless steel blade is rated to sustain a 100W laser that has a beam diameter of 10mm. This is suitable for use with the air cooled beam dump shown. Users must ensure the external beam dump can absorb and dissipate the laser power.

The PEL ratings below are for a standard stainless steel blade.
