35-795 12.5 mm Dia. N-BK7 Wedge Prism; t=1.5 mm VIS-NIR 400-1000nm

This 35-795 optical component is a Wedge Prism, a type of prism with a triangular base and one angled face, designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically between 400 and 1000 nanometers. The prism is sourced from the reputable vendor, Edmund Optics.

The prism is made from N-BK7, a high-quality borosilicate glass commonly used in optical applications due to its excellent optical properties. The prism's base shape is circular, with a diameter of 12.5 millimeters, providing a substantial surface area for light interaction.

The prism's thickness is 1.5 millimeters, a crucial specification as it directly impacts the prism's optical performance. The wedge angle, which is the angle between the entrance and exit faces, is 0.03374245042880637 radians or approximately 1.94 degrees. This angle is responsible for the prism's refractive properties, causing light to bend as it passes through the prism.

The prism's coatings are another critical aspect of its design. Both the front and back surfaces are coated with "edm visnir0sp2002000", a coating specifically designed for use in the VIS-NIR spectrum. This coating enhances the prism's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency of the optical system in which it is used.
