The PTK1303 is a right-angle prism made from N-BK7, a type of borosilicate glass developed by Schott. This material is known for its excellent optical transmission and low coefficient of thermal expansion, making it a popular choice for a wide range of optical applications. The prism has a volume base shape, with each side measuring 12.5 mm, resulting in a cube-like structure.
The prism features a protected aluminium coating on the hypotenuse, designed to enhance its reflective properties. This coating is specifically designed for use within the wavelength range of 450-650 nm, which covers the visible light spectrum. The coating is identified as 'kni mv2', which is a proprietary coating developed by Knight Optical, the vendor for this prism.
The prism's coating on the back surface is also 'kni mv2', ensuring consistent performance across all reflective surfaces. This prism is currently in stock at Knight Optical, as indicated by the 'weblink status' field in the item data.
