The Enhanced Watt Pilot incorporates a motor-driven rotating quartz λ/2 phase waveplate and one or two Thin Film polarizers that separate s-polarized and p-polarized beams in parallel directions. 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.
The Watt Pilot is essential in systems in which stable adjustments to laser power are necessary. Despite the stand-alone device look, the motorized attenuator is compact and can be easily integrated into custom optical systems.
Custom wavelengths are available upon request.
