14 May 2019 BRD Optical provide high-power polarized prisms of single wavelength or broad band.These PBS are made of glass material and polarizing effect can be achieved by means of mdium beam splitting film.The optical glue structure in the middle can withstand high power.
After the non-polarized light passes through PBS,the pure P polarizztion comes out along the propagation direction,and the side refection is S polarization.The transmitted P polarization has a good extinction ratio,which can range from 500:1 to 10000:1 depending on the coating film.
