PG&O Introduces Beamsplitter with 1000:1 Extinction Ratio

May 2, 2022

Santa Ana, CA – March 14, 2022 –Precision Glass & Optics (PG&O –, a global leader in optical manufacturing, precision thin-film coatings, and complete optical solutions, announces the new polarizing beamsplitter cube that splits up the S & P polarization of light with extinction ratios from Tp/Ts 1000:1 and Rs/Rp 1000:1. PG&O’s specialty 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 nm – 2500 nm, these innovative beamsplitters can be customized to meet the critical specifications of customers.

According to President Dan Bukaty, Jr., “With our new capability, our 1000:1 extinction ratios fully maximizes the split between S&P polarization which is an essential factor in many laser tasks. With the new transmission and reflection ratios we elevate our level of proficiency in beamsplitter thin-film coating technology. We’re excited to provide this expanded offering to new and existing customers.” 

The company’s previously announced 200:1 and the new 1000:1 extinction cube polarizing beamsplitters are both used in applications where two polarization components need to be analyzed, or used simultaneously. Ideal for use in the ultraviolet, visible, near-infrared and mid-IR wavelength ranges. To learn more about PG&O’s cube beamsplitter technology, please go to:
