Dämpfungsglied mit großer Apertur

Dämpfungsglied mit großer Apertur

Bandwidth Up to ±50 nm
Attenuation range @ CWL Up to 0.3-99%
Typical application High power and ultrafast lasers
Damage threshold >5 J/cm2 10 Hz, 10 ns, 1064 nm; or >100 mJ/cm2 1 kHz 100 fs, 800 nm
The main feature of Large Aperture Attenuators is 30 mm and larger clear apertures. 

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 integration.
