The PS908L-B is a right-angle prism crafted from N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and versatility. This prism, sourced from Thorlabs, is designed with a 20 mm arc and features broadband anti-reflection (BBAR) coating on both the front and right faces, enhancing transmission within the 650-1050 nm wavelength range.
The right-angle geometry of this prism allows for 90-degree deflection of light, making it an ideal component for a wide range of applications, such as beam steering, splitting, and combining. Its dimensions, with a length (l) of 20 mm and a width (x) of 28.3 mm, contribute to its robust construction, ensuring reliable performance under various conditions.
The PS908L-B prism's coating is another noteworthy feature. The BBAR coating reduces surface reflections, thereby increasing the amount of light transmitted through the prism. This coating is particularly beneficial for applications that require high transmission and minimal loss, such as imaging systems, interferometers, and laser-based systems.
