Manual Attenuators

This device will allow the user to externally vary the power delivered from the laser without changing beam quality or beam path. Many lasers only vary their output power by pulsing full power on and off, and this does not always provide the fine control needed for some materials. The device will give infinitely variable control of the transmitted beam from approximately 6% to 100%. Below 100W the manual attenuator can be used air-cooled, above 100W the optional water jacket should be used.
