Product Details

Two Channel Polarizing Beamsplitter Cube

Overview:

Standard polarizing beamsplitter cube does not have high advantate on the extinction ratio of reflected channel . This Two Channel Polarizing Beamsplitter Cube with our unique coating technique can achieve high performance not only at transmitted but also at reflected channels. It features greater than 97% transmission of p-polarized beam as well as high extinction ration of greater than 1000:1 at transmitted channel and 200:1 at reflected channel. It is widely used in interferometer applications.
