BK7 Glass Prism is manufactured from borosilicate crown glass with high optical homogeneity and low bubble content. It operates based on refraction and internal reflection principles to redirect or invert light paths. The prism is produced through precision cutting, grinding, and polishing to achieve accurate angular tolerances and smooth optical surfaces. It is widely used in imaging systems, laser setups, microscopes, and optical alignment instruments. BK7 material provides excellent transmission in visible wavelengths and stable refractive properties.
