Attention! You can customise this product to your needs.

ultraFAST Watt Pilot is intended for laser pulses <100 fs. Construction incorporates rotating λ/2 waveplate and two high performance broadband 72° thin film polarizers (TFP). Half waveplate rotates the polarization before the TFP which split the beam into two parallel s-polarized and p-polarized beams. The intensity ratio of separated beams is continuously tuned by rotating the waveplate.
There are 2 standardized types of ultraFAST attenuators: one for maximum transmitted energy and one for maximum blocked beam.
However any intermediate versions and other wavelength ranges are available upon request.
