UFBS2080 1in Dia. 20:80 (R:T) Infrasil Low-GDD Ultrafast Beamsplitter, 600-1500nm, 45° AOI

The UFBS2080 is a high-quality beam splitter from Thorlabs, designed for use in ultrafast laser systems. This beam splitter features a 1-inch diameter and a 20:80 (R:T) beam splitting ratio, making it ideal for applications that require a high transmission rate.

The beam splitter is made from Infrasil, a type of fused silica known for its low optical absorption and excellent transmission properties in the near-infrared region. This makes the UFBS2080 suitable for use with lasers operating in the 600-1500nm wavelength range.

The UFBS2080 has a thin lens shape, with a thickness of just 1.5mm. This design helps to minimize group delay dispersion (GDD), which can be a significant issue in ultrafast laser systems. The beam splitter also features a 45° angle of incidence (AOI), which is typical for beam splitters used in laser systems.

The front surface of the beam splitter is coated with a proprietary coating (tho ufbs2080), which is designed to enhance its performance. This coating helps to ensure high transmission and low reflection, making the UFBS2080 a reliable and efficient component in any laser system.

According to the vendor's website, the UFBS2080 is currently in stock, making it readily available for immediate use. Further information about this product, including detailed specifications and purchasing options, can be found on the Thorlabs website.
