Description


The LST500-123 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. Special dielectric mirrors are available for OEM applications. See the Mechanical Drawing for dimensions. Also see the Application Notes in the Technical Information menu for important operational issues including: thermal mounting, user-built circuits, polarization, lifetime, jitter, vacuum operation, and contamination.
