Variable Beamsplitter/Attenuator
Home >Products>Optical Element>Beamsplitter

Variable Beamsplitter/Attenuator is a combination of a polarization Beamsplitter cube (PBS) and a zero order half waveplate made of crystal quartz. Variable Beamsplitter/Attenuator is used to continuously vary the transmitted intensity of a linearly polarized beam by rotating the waveplate, which can achieve split ratios (T:R) of 1:99 to 95:1. It is widely used in holography, interferometry and other applications.

Continuously Variable Split Ratios (T:R) from 1:99 to 95:1
High Extinction Ratio Tp/Ts>1000:1
Zero Order Half Waveplate
Two M4 hole available for mounting
RoHS Compliant
