Specifications
| Product Type | Collinear type - Manual |

Description
- Divides laser beam into two parallel beams of manually adjustable intensity ratio
- Large dynamic range
- Transmitted beam shift ~0.5 mm
- High optical damage threshold
- S-Pol attenuation range ~ 0.25% - 99.0%
- P-Pol attenuation range ~ 0.5 % - 95.0 %
This Variable Attenuator / Beamsplitter consists of special design Opto-mechanical Adapter and Precision Opto-mechanical Holder 840-0197. Two Thin Film Brewster type polarizers, which reflect s-polarized light while transmitting p-polarized light, are housed into Adapter. Quartz Half Waveplates are housed in rotating holder 840-0197.
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 840-0197 allows to adjust angle of incidence of the Thin Film Brewster type polarizers by ±2° and to get the maximum polarization contrast.
Note: Movable base 820-0090, Rod Holder 820-0050-02 and standard rod should be ordered separately.
