Dichroic Polarizing Film Sheet Polarizer 400-700nm, Linearly Polarized Beam

Overview:

Dichroic Film Sheet Polarizer featuring a dichroic film sheet is epoxied between two protective glass plates. When a natural beam travels through the dichroic film sheet, the rejected polarization is highly absorbed while the transmitted polarization transmits with a weak absorption, making them to be used converting randomly polarized beam into linearly polarized beam.


Compared to polarizing prisms, these dichroic film sheet polarizers offer much bigger size and acceptable angle>20deg.


These 400-700nm dichroic film sheet polarizers provide much higher extinction ratio 1000:1 and acceptable angle>20 deg than polarizing plate beamsplitters at the same wavelength range except the fact that they are limit to use in low-power applications.
