Welcome to Sintec Optronics


         Products             CO2 Compact Manual Attenuator

We supply CO2 compact Manual Attenuators that allow you to vary laser output power.


Our Manual Attenuators allow the user to externally vary the power delivered from the laser. Many lasers only vary their output power by pulsing full power on and off, and this does not always provide the fine levels of control needed for some materials. This device will give infinitely variable control of the transmitted beam from approximately 6% to 100%. Using ‘enhanced’ coated Brewster plates the transmittance range can be changed from 0.04% to 98%.


When used with a laser of up to 100W the CO2 compact Manual Attenuator can left be air-cooled. When used above 100W then the optional water-cooled jacket should also be fitted.
