Description
- Divides laser beam into two beams of manually adjustable intensity ratio separated by 68° angle
- Large dynamic range
- Transmitted beam shift ~0.5 mm
- High optical damage threshold
- Attenuation range for transmitted beam: 0.5%-95%
- Attenuation range for reflected beam: 5%-99.5%
This Variable Attenuator / Beamsplitter consists of special design Opto-mechanical Adapter for Polarizer at 56° 840-0117A or 840-0118A and Precision Opto-mechanical Holder 840-0197. The Thin Film Brewster type polarizer, which reflect s-polarized light at 56° while transmitting p-polarized light, is housed into Adapter for Polarizer at 56°. 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 polarizer by ±2° and to get the maximum polarization contrast.
Note: Solid Base Height Extender 820-0210 and Standard Rod 820-0020-20 should be ordered separately.
