The Standard Watt Pilot incorporates a motor-driven rotating quartz λ/2 phase waveplate and High Energy Polarizing Beamsplitter Cube that separates s-polarized and p-polarized beams in orthogonal directions. Pure p-polarization should be selected for maximum transmission and pure s-polarization for maximum attenuation. The intensity ratio of these two 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.

A detachable beam dump is complementary with the product. Custom wavelengths are available upon request.
