Rotator 100mm Quartz Polarization Optics Beamsplitter Cubes 2500nm
Quartz Polarization Rotator,Made of quartz, 200-2500nm, Up to 100mm diameter
Polarizing Beamsplitting Cubes are offered in six sizes and with five beamsplitting coating ranges. These cubes separate the s- and p-polarization components by reflecting the s component with the dielectric beamsplitter coating, while allowing the p component to pass. These cubes are designed to be used with the transmitted beam, which offers an extinction ratio of TP:TS > 1000:1, except the PBS519 2" 420 - 680 nm cube, which offers an average extinction ratio of > 1000:1 over the wavelength range. The reflected beam will only have an extinction ratio of roughly 20:1 to 100:1, depending on the beamsplitter.
The dielectric beamsplitting coating is applied to the hypotenuse of one of the two prisms that make up the cube. Then, cement is used to bind the two prism halves together . The engraved dot on the top of the cube indicates the prism with the beamsplitting coating. Light can be input into any of the polished faces to separate the S and P polarizations. Cubes larger than 5 mm also feature engraved arrows indicating one possible orientation.
