PTK0603 N-BK7 Right Angle Prism; 6.25 mm Protected Aluminium 450-650nm Hypotenuse

This is a right-angle prism, specifically the PTK0603 model, sourced from Knight Optical. The prism is made of N-BK7 equivalent material, which is a type of borosilicate crown 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 has a geometry where all three sides (a, b, and c) measure 6.25 mm each, classifying it under the volume prism category. The base shape is a right angle, making it ideal for applications requiring total internal reflection.

The coating on the back surface of the prism is KNI MV2, a protected aluminium coating designed for use in the 450-650 nm wavelength range. This coating enhances the prism's reflectivity and durability, making it suitable for various applications, including but not limited to, beam folding, image reflection, and light splitting.
