Optical properties of prisms and our manufacturing achievements.
A prism is a wedge-shaped optical element made of a plane that forms an angle with the incident and exit surfaces of light. It is used to change the direction of light passing through by utilizing refraction (deflection), to change the direction of light of different wavelengths by utilizing dispersion (spectroscopy), or to align the direction of light (coherence). The prism in the photo is designed so that the incident light undergoes total internal reflection at a surface tilted at 45 degrees, changing its direction by 90 degrees, and the lens surface formed at the prism's exit surface alters the way the light spreads. Thus, composite elements of prisms and lenses are also possible.
