Optical Prism, a transparent object surrounded by two planes that intersect but are not parallel to each other, is used to split light or disperse light beams. An optical prism is a polyhedron made of ...

A glass prism is a transparent object having two triangular ends and three rectangular sides. The refraction of light in glass prism is different from a glass slab. This is because in glass prism ...

Some leading manufacturers’ solution to the Pechan-prism problem are special multi-layer reflective coatings that get 99.5 percent reflection on the mirrored surfaces.

After decades of physics-based theorizing, researchers have succeeded in creating a novel optical metamaterial using conventional materials. Its enhanced electromagnetic effect may make true one ...

The optical systems company Zeiss has supplied NASA and the ESA with high-grade glass components for years, including lenses for the James Webb Space Telescope and lunar cameras for the Apollo ...
