Description

Laser Shutter LMT-LS-200-24 and LMT-LS-200SIL-24

The laser beam shutters of the LMT-LS-200 series are a combination of a shutter and an integrated beam trap. They are used to automatically or manually turn off the laser beam during unauthorized access if the beam is not needed. The shutters are suitable for use with lasers of 20 W cw power (with a beam diameter of 2 mm) and up to 100 W (with a beam diameter of 10 mm). For higher output power, a mirrored or ceramic shutter and a matching external beam dump can be used.

All LMT-LS-200 series shutters can be used as free-standing shutters for manual or remote beam switching.

When open, the beam passes through a 50mm aperture with a threaded connector for beam guides.

The shutter LMT-LS-200SIL-24 is available as a double version of the LMT-LS-200-24 and thus meets the maximum possible performance level "e" according to the Machinery Directive.
