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 –C2 suffix for CO2 laser use (see LST500-C2). 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. Use suffix –1 for 1064 nm, -2 for 532 nm, -3 for 355 nm, -4 for 266 nm, and –12 for 532 + 1064 nm, -123 for 355 + 532 + 1064 nm harmonic mirror (lower damage threshold, see LST500-123).
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.
