The Ultrafast version of the attenuator is intended for laser pulses of <100 fs. It incorporates a rotating Achromatic λ/2 phase waveplate and two high-performance Broadband 72° Thin Film Polarizers that separate s-polarized and p-polarized beams in parallel directions. The polarizers are housed in a specially designed optomechanical holder mounted together with a precision kinematic adjustable waveplate holder. 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 beam attenuation.

Custom wavelengths are available upon request.
