The PS915H-A is a right-angle prism made from N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties. This prism, sourced from Thorlabs, is designed with a 15 mm arc and a hypotenuse that supports wavelengths from 350 to 700 nm, making it suitable for a wide range of applications.
The prism's geometry is another notable feature. With a length (l) of 15 mm and a base width (x) of 21.2 mm, it offers a substantial surface area for light reflection. The base shape is a volume prism, which is ideal for applications requiring total internal reflection.
The coating on the back surface of the prism is THo A Bbar, a broadband anti-reflection coating that reduces reflection and increases transmission. This coating is particularly beneficial when the prism is used in multi-pass systems or where high transmission is required.
