Laser Beam Attenuator, Enhanced Version
The Enhanced version of the attenuator incorporates a rotating quartz λ/2 phase waveplate and one or two 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. Pure p-polarization should be selected for maximum transmission and pure s-polarization for maximum attenuation. The intensity ratio of separated beams is continuously tuned by rotating the waveplate in the holder.
Custom wavelengths are available upon request.
