Optical Glass Polarization Optics Two Channel PBS Polarization Beamsplitter Cube
Optical glass Size 10-50mm High Performance Two Channel PBS
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. MAP Optics 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.
