PTK0502 N-BK7 Right Angle Prism; 5 mm Protected Aluminium 450-650nm Hypotenuse

The PTK0502 N-BK7 Right Angle Prism is a high-quality optical component sourced from Knight Optical. This prism is designed with a right-angle geometry, making it ideal for a wide range of applications where light needs to be reflected at a 90-degree angle.

The prism is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The prism's dimensions are 5 mm x 5 mm x 5 mm, providing a compact yet effective optical solution.

The prism's coating is another notable feature. It is protected with a 588 nm aluminum coating, specifically designed for use in the visible light spectrum (450-650 nm). This coating enhances the prism's reflectivity, making it more efficient in its light-redirecting role. The 'protected' nature of the coating ensures that it is less susceptible to damage from environmental factors, increasing the prism's durability and lifespan.

The prism's geometry is designed as a 'Volume' base shape, which means it has a flat base and a flat hypotenuse. This design allows for efficient light transmission and minimal distortion. The hypotenuse, the longest side of the prism, is the entry and exit face, making it the point of incidence and reflection for the incoming light.
