Motorized Variable Attenuator for Linearly Polarized Laser Beam 990-0070M

This Motorized Variable Attenuator / Beamsplitter consists of special design Opto-mechanical Adapter and Precision Opto-mechanical Holder 840-0193. Two Thin Film Brewster type polarizers, which reflect s-polarized light while transmitting p-polarized light, are housed into the Adapter. Quartz Half Waveplates are housed in Motorized Rotation Stage 960-0161.

 

The intensity ratio of those two beams may be continuously varied without alteration of other beam parameters by rotating the waveplate. The intensity of either exit beam, or their intensity ratio, can be controlled over a wide dynamic range. P-polarization could be selected for maximum transmission, or high-purity s-polarization could be reflected when maximum attenuation of the transmitted beam takes place. The holder 840-0193 allows to adjust angle of incidence of the Thin Film Brewster type polarizers by ±2° and to get the maximum polarization contrast.


Note: Controllers and Power supllies should be ordered separately.
