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 –C2 suffix for CO2 laser use. Choose the –IR suffix IR use, starting at about 700 nm. The standard over-coated aluminum mirror is good from deep UV to about 700 nm (see LST500-AL). Special dielectric mirrors are available for OEM applications (see LST500-123). Use suffix –1 for 1064 nm, -2 for 532 nm, -3 for 355 nm, -4 for 266 nm, and –12 for 532 + 1064 nm harmonic mirror (lower damage threshold). 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.
