45-557 25 mm Dia. N-BK7 Wedge Prism; t=3 mm Uncoated

The 45-557 is a 25 mm diameter Wedge Prism made from N-BK7 Schott glass, featuring a thickness of 3 mm and a nominal wedge angle of 10 degrees. This prism is uncoated, providing a cost-effective solution for applications where coating is not required or preferred. The N-BK7 Schott glass, also known as BK7, is a popular material for optical components due to its excellent homogeneity, low optical dispersion, and high transparency in the visible spectrum.

The 45-557 Wedge Prism is sourced from Edmund Optics, a reputable vendor in the optical industry. The prism's geometry, including its 25 mm diameter and 3 mm thickness, ensures robustness and versatility in various applications. The wedge angle, calculated to be approximately 0.316 radians (10 degrees), is responsible for the prism's primary function: to deviate or bend light by a specific angle.

This prism is ideal for applications that require precise light control, such as beam steering, beam splitting, or angular image compensation. Its uncoated nature makes it suitable for use in environments where anti-reflection or other specialized coatings are not necessary. However, for applications that demand specific reflective or transmissive properties, coated versions of this prism are available.
