Description
LST4WBK2-D123 Laser Shutters are 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. For more information about our LST4WBK2-D123 Laser Shutters, 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.
