The difference between prism and triangular prism

1, Properties: Prism is a polyhedron made of transparent materials, such as glass and crystal. The prism is an optical instrument made of transparent material with a triangular cross section.

2. Use: Prisms are widely used in optical instruments. For example, in spectral instruments, the equilateral prism is commonly used to decompose the synthesized light into dispersive prisms. In periscope, binoculars and other instruments, the so-called total reflection prism is used to change the direction of light and adjust its imaging position.
