Description
For normal polarization Beamsplitter cube(PBS), the extinction ratio of the beam from reflected channel is not good, not suitable for special application which has high request for reflected channel, like interferometer. Union Optic can offer high performance two channel PBS, due to our unique coating design, we can improve the extinction ratio of reflected channel. High performance two channel PBS is always used in interferometer.
Feature
-
Widely Used In Interferometer Application
-
High Extinction Ratio for Both Transmitted & Reflected Channels
-
Good Wavefront Distortion for Both Transmitted & Reflected Channels
-
RoHS Compliant
