The PS915H-C is a right-angle prism made from N-BK7 Schott glass, a popular material for optical components due to its excellent optical properties and wide transparency range. This prism, sourced from Thorlabs, is designed for use in the 1050-1700nm wavelength range, making it suitable for a variety of applications in the near-infrared spectrum.
The prism features a hypotenuse angle of 15 degrees, which is the angle between the base and the longest side of the prism. This specific angle is commonly used in right-angle prisms to achieve total internal reflection, a key principle in many optical systems. The hypotenuse is coated with a broadband anti-reflection coating (tho c bbar), which reduces reflection and increases transmission, further enhancing the prism's performance.
In terms of geometry, the prism has a length (l) of 15 mm and a base width (x) of 21.2 mm. This compact size makes it suitable for use in compact optical systems where space is at a premium. The prism's volume shape and right-angle design allow for versatile use in various optical arrangements.
