BST17 Dia:2in 70:30 (R:T) UVFS Plate Beamsplitter; Coating: 700-1100nm; t=8 mm

The BST17 Dia:2in 70:30 (R:T) UVFS Plate Beamsplitter is a high-quality optical component sourced from Thorlabs. This beamsplitter is designed with a circular geometry, featuring a diameter of 50.8 mm and a thickness of 8 mm, making it suitable for a wide range of optical applications.

The beamsplitter is made from UVFS material, identified as MAL-1965 in the material database. It is coated with a specialized coating, referred to as tho 7030uvbs7001100, which is specifically designed for use in the 700-1100nm wavelength range. This coating ensures optimal performance and reliability in the specified wavelength range.

The BST17 Beamsplitter features a 70:30 (R:T) split ratio, meaning that 70% of the incident light is reflected while 30% is transmitted. This split ratio is consistent across the entire specified wavelength range. The physical data of the beamsplitter includes a reflection of 0.7 and a transmission of 0.3, which aligns with the stated split ratio.

The beamsplitter is designed in a thin lens shape, which can be beneficial in certain optical systems due to its compact size and reduced weight. The vendor, Thorlabs, indicates that this item is currently in stock, making it readily available for immediate use.
