Precision Glass & Optics (PG&O) has launched the new polarising beamsplitter cube that splits up the S & P polarisation of light with extinction ratios from Tp/Ts 1000:1 and Rs/Rp 1000:1. The company’s beamsplitters are designed to work with lasers and are well-suited for other optical applications. 

The entrance and exit faces of the cube beamsplitters are carefully coated with anti-reflection (AR) coatings to greatly improve the performance of the cube. With advanced optical coatings from PG&O that operate from 200-2,500nm, these beamsplitters can be customised to meet the critical specifications of customers.

The company’s previously announced 200:1 and the new 1000:1 extinction cube polarising beamsplitters are both used in applications where two polarisation components need to be analysed, or used simultaneously. Ideal for use in the ultraviolet, visible, near-infrared and mid-IR wavelength ranges.
