Specifications updated on April 27, 2021
Compatible system controllers are CX4000B or user-built circuits designed around 24 VDC.
Options are available using a suffix code system. Many options cannot be installed after manufacture, so choose carefully. Standard 1.000” round dielectric optics on 1 mm substrates are used from major industry suppliers. Mirrors are bonded into our moving assembly. Use suffix –1 for 1064 nm, -2 for 532 nm, -3 for 355 nm, -4 for 266 nm, and –12 for 532+1064 harmonic mirror (lower damage threshold). Use –C2 for CO2 use, -800 for Ti:Sapphire. Additional mirrors are available for specific laser lines. Contact our application engineers. Referring to the plane of the Base Plate, CX4000B controller can be calibrated for horizontal or vertical calibration. Horizontal is the default (as shown in product photo). Circuits not using dampening on closure will generate longer settling times for closure spec, up to 100 msec maximum.
Special Considerations for this model include precautions to use proper laser with installed mirror, and add chiller plate accessory for loads over 50 watts. Beam tube abutment to input/output is typical; diffuse back-scatter is a little higher on this model than on others due to compact thickness.
Restricted use for this model include mirror choice compatible with laser, and observance of gravity mounting orientation for critical timing applications.
See the Mechanical Drawing tab 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.
