NEW: optical beam variable attenuator / separator by Altechna

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.

Product features:

* Ideal for ultraSHORT femtosecond lasers

* Divides laser beam into two parallel beams of manually adjustable intensity ratio

* High Optical damage threshold

* Low dispersion for femtosecond laser pulses
