PG&O Introduces Beamsplitter with 1000:1 Extinction Ratio

Polarizing beamsplitter cube is ideal for laser applications

Published: Tuesday, April 5, 2022 - 12:01

(PG&O: Santa Ana, CA) -- Precision Glass & Optics (PG&O), a global leader in optical manufacturing, precision thin-film coatings, and complete optical solutions, announces a new polarizing beamsplitter cube that splits up the S&P polarization of light with extinction ratios from Tp/Ts 1,000:1 and Rs/Rp 1,000:1. 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 to 2500 nm, these innovative beamsplitters can be customized to meet the critical specifications of customers.

 “With our new capability, our 1,000:1 extinction ratios fully maximize the split between S&P polarization which is an essential factor in many laser tasks,” says PG&O president, Dan Bukaty Jr. “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 1,000:1 extinction cube polarizing beamsplitters are both used in applications where two polarization components need to be analyzed, or used simultaneously. They're ideal for use in the ultraviolet, visible, near-infrared, and mid-IR wavelength ranges. Youj can learn more about PG&O’s cube beamsplitter technology here.

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 customized and specified (up to 24 in. diameter) to meet exact wavelength and/or angle requirements.
