Attention! You can customise this product to your needs.
Ultrafast version of attenuator is intended for laser pulses <100 fs. Construction incorporates rotating λ/2 waveplate and two high performance broadband 72° thin film polarizers (TFP). Polarizers are housed in special design opto-mechanical adapter, which is mounted in precision opto-mechanical holder 5APH79T-1.

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 in the holder. 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.
varna Ideal for ultraSHORT femtosecond lasers
varna Divides laser beam into two parallel beams of manually adjustable intensity ratio
varna High Optical damage threshold
varna Low dispersion for femtosecond laser pulses
