BST10 Dia:1in 70:30 (R:T) UVFS Plate Beamsplitter; Coating: 400-700nm; t=5 mm

The BST10 Dia:1in 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 1 inch (25.4 mm) and a thickness of 5 mm, making it suitable for a wide range of optical applications.

The beamsplitter is made from UVFS material, specifically identified as "uvfs mal- 1965" in the item data. This material is known for its excellent optical properties, ensuring high-performance operation in the intended application.

The BST10 features a 70:30 beam splitting ratio, where 70% of the incident light is reflected, and 30% is transmitted. This ratio is maintained at a central wavelength of 633 nm, making it ideal for applications that require precise beam splitting at this wavelength.

The beamsplitter is coated with a special coating, "tho 7030uvbs400700", which is applied to the front surface. This coating is designed to operate within a wavelength range of 400-700 nm, providing optimal performance within this spectral range.

The BST10 is classified as a thin lens beamsplitter, which means it has a flat front and back surface, with the beamsplitter functionality occurring at a specific depth within the material. This design allows for easy integration into optical systems.
