Large Aperture Attenuators
The main feature of Large Aperture Attenuators is 30 mm and larger
The assembly incorporates rotating λ/2 phase Waveplate and one or two
thin film polarizers. Half waveplate rotates the polarization
before TFP, which separate s-polarized and p-polarized beams. The
intensity ratio of separated beams is continuously tuned by
rotating the waveplate in the holder.
Polarizers are housed in special design opto-mechanical adapter, that
allows angle adjustment to find the optimal angle of incidence.
Some models come with beam dump included in the assembly for easier
