The high reliability LST-5VDC optical shutter provides the best value with 5V direct drive. Its compact 2” x 1” x 0.4” package size with 3mm aperture provides the optimum package to aperture size ratio. The electrical drive becomes the simplest form for users with 5V direct drive. Lowest cost electrical drive, a switch, is achieved. Thermal management becomes negligible with only 2.5W thermal power dissipation when holding open. Considerations for all laser shutters and optical shutters include proximity to high magnetic fields and strict observance of optical power rating. Subjecting the optical shutter to “large” size dust particles and debris could inhibit the optical shutter motion. 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. See the Product Matrix page to compare laser shutter models.
