Polarising beamsplitters

Precision Glass & Optics has introduced a new polarising beamsplitter cube that splits up the S & P polarization of light with an extinction ratio of Tp/Ts 200:1 and higher. This thin film coating innovation is especially important for high-power laser applications up to 10J/cm2 pulsed and continuous wave (CW). All of the entrance and exit faces are coated with PG&O’s high-power, anti-reflection coatings to improve the overall performance of the cube. These advanced optical coatings operate at wavelengths ranging from 200-2500nm and can be customised to meet unique requirements.

The new beamsplitters are useful in applications where the two polarisation components are to be analysed, or used simultaneously. PG&O’s optical thin film coating technology, along with the company’s large in-house inventory of optical glass products, and full optical fabrication facility, provides highly precise optical coatings that can be customised  and specified (up to 24 inches diameter) to meet exact wavelength and/or angle requirements.
