The TECHSPEC cube beam splitter (non-polarizing type) is composed of two right-angle prisms. A suitable optical thin film is deposited on the sloped surface of one prism to function as a beam splitter, and the sloped surfaces of the two prisms are joined to form a cube shape. This film divides light at a specified ratio for both transmission and reflection at a wavelength of 550nm in the visible range when non-polarized light is incident. Since a dielectric multilayer film is used for the film that functions as the beam splitter, there is almost no light absorption loss due to the film itself (however, due to the difficulty of broad-band wavelength control with dielectric films, there may be different splitting ratios at the ends of the visible range). Additionally, a broad-band single-layer anti-reflection coating (MgF2 single) is applied to all four surfaces of the input/output faces, which is effective in reducing ghost images. ■ Non-polarizing type beam splitter ■ Dielectric multilayer film used for B/S coating ■ Three types of R/T ratios available *You can download the catalog from Edmund Optics Japan that features this product from the link below.

The TECHSPEC N-BK7 corner cube is designed to retroreflect any light ray or beam entering the prism, regardless of the angle of incidence, and return it in the direction of incidence. Retroreflection using mirrors can only be performed at normal incidence. Therefore, corner cube prisms are useful when you want to reduce the difficulty of optical axis adjustment or shorten working time. We offer both types with metal coatings (silver-coated) on all three reflective surfaces and uncoated types. The silver-coated type is suitable when you want to achieve wide-angle retroreflection, while the uncoated type is appropriate when maximizing reflectivity (100% reflection) by utilizing the phenomenon of total internal reflection. The incident surface of the prism can be selected as uncoated or with an anti-reflective coating. The anti-reflective coating is optimized for wavelengths in the visible range as well as in the near-infrared range, including 1064nm and 1550nm. ■ Retroreflective prism ■ Angular accuracy of up to 3 seconds ■ Convenient for alignment ■ Various coating options (for enhanced reflective coatings and anti-reflective coatings) ■ Framed versions are also available *You can download the catalog from Edmund Optics Japan below.
