LST500 DESCRIPTION

The LST500 laser shutter model is designed for use as a laser safety interlock and processing applications. The shutter provides TTL output position sensors for the open and closed states as standard equipment. Compatible system controllers are CX4000B or user-built circuits designed around 24 VDC @ 2 A.

Options are available using a suffix code system. Many options cannot be installed after manufacture, so choose carefully. Choose the – IR suffix for IR use, starting at about 700 nm. The standard over-coated aluminum mirror is good from deep UV to about 700 nm. Special dielectric mirrors are available for OEM applications.
