Principle of operation:The principle of operation is based on the ‘Brewster angle’. When linearly polarised light is incident on an airoptical material interface (uncoated), usually some of the light is reflected and some transmitted. However, when linearly polarised in the orientation (known as ‘P’ polarisation), there is no reflected light; 100% is transmitted into the material, provided the angle of incidence is equal to the Brewster angle. This is not so when the polarisation is in the perpendicular direction (known as ‘S’ polarisation).
Our manual attenuator allows the user to externally vary the power delivered from the laser. Many lasers only vary their output by pulsing full power on and off, and this does not always provide fine levels of control needed in some materials. This device will give infinitely variable control of the transmitted beam from approximately 6% to 100%. An optional manual attenuator with ‘enhanced’ coated Brewster plates provides a transmittance to as low as 0.04% up to 98%. Both types of manual attenuator can come as a water-cooled version.

Watt Pilot is a laser beam intensity attenuator. Enhanced version contains a rotating quartz λ/2 phase waveplate and one or two thin film plate polarizers for parallel s-polarized and p-polarizer beam separation, meanwhile Standard version attenuator contains a single polarizing cube beam splitter for orthogonal s-polarized and p-polarized beams separation. The intensity ratio of two separated beams is continuously tuned by rotating the waveplate. Despite the stand-alone look, Watt Pilot motorized attenuator is a compact, rigid and precise device and it can be easily integrated into custom optical systems.

Example of performance provided by attenuator comprising a waveplate and a polarizer.
PowerXP motorized attenuators are reliable solution for industrial applications. Each attenuator includes motorized rotating quartz λ/2 phase waveplate, optically aligned to a single/ dual thin film polarizer or polarizing beamsplitting cube which separates the input beam into individual s-polarized and p-polarized parallel or perpendicular output beams. The intensity ratio of separated beams is continuously tuned by rotating the waveplate. S-polarized beam output can be used for high purity s-polarized beam requiring applications and P-polarized beam output for power control and attenuation applications. High energy applications compatible optics, fast rotation speed of PowerXP Maxi and Cube versions and small footprint of Compact version makes PowerXP motorized attenuators a go-to solution for power control, attenuation and beam-splitting in demanding laser processing applications.

5.1 Laser Beam Attenuator, Enhanced Version
The Enhanced version of the attenuator incorporates a rotating quartz λ/2 phase waveplate and one or two Thin Film Polarizers that separate s-polarized and p-polarized beams in parallel directions. The polarizers are housed in a specially designed opto-mechanical holder mounted together with a precision kinematic adjustable waveplate holder. Pure p-polarization should be selected for maximum transmission and pure s-polarization for maximum attenuation. The intensity ratio of separated beams is continuously tuned by rotating the waveplate in the holder.
