49-419 N-BK7 Rhomboid Prism; 10.5 x 15 x 21.2 mm Uncoated

The 49-419 N-BK7 Rhomboid Prism is a high-quality optical component sourced from Edmund Optics. This prism, with its unique rhombic shape, measures 10.5 x 15 x 21.2 mm, making it suitable for a wide range of optical applications.

The prism is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material, also known as Schott glass, is characterized by a low coefficient of thermal expansion and a high refractive index, making it an ideal choice for precision optical systems.

The prism is uncoated, meaning it does not have any additional layers of material applied to its surface. While coatings can enhance certain optical properties, an uncoated prism can offer advantages such as broadband operation, lower cost, and simplicity.

The geometry of the prism is defined by its 'a', 'b', 'c', and 'd' dimensions. In this case, 'a' and 'b' are equal at 15 mm, while 'c' is 10.5 mm and 'd' is 21.2 mm. This specific geometry is often used in optical systems to alter the path of light, providing functionality such as beam deviation, image rotation, or dispersion.

Please note that the prism's properties are optimized for a wavelength of 632.8 nm. This is typical for many optical components and aligns with the emission line of a common laser type, the helium-neon laser.
