Polarizer

Waveplates (retarders) are made from birefringent materials which introduce a phase difference between the fast and slow principal axis of the waveplate. The optical axis of waveplate is parallel to the face. Light incident normal to the surface will be split to components polarized parallel and perpendicular to the optical axis with different refractive index and veloci...

Super Achromatic Waveplate is similar to achromatic waveplate but providing a flat retardance over a super broadband wavelength range. Normal achromatic waveplate consists of one quartz plate and one MgF2 plate, which has only few hundreds of nanometer wavelength range. Union Optic’s super achromatic waveplate is made from three material, quartz, MgF2 and sapphire, wh...

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...
