Product Introduction
Prisms are mainly used in optical instruments to decompose composite light into a spectrum or to change the direction of light rays. The working principle of prisms is based on the laws of refraction and the phenomenon of dispersion of light. When light rays enter one medium from another, refraction occurs, meaning the direction of propagation of the light rays changes. Different wavelengths of light have different refractive indices within a prism, and therefore undergo varying degrees of deflection after passing through the prism, thereby decomposing composite light into a spectrum.
Right-angle Prism: It features a right angle and two 45° inclined planes. These angles allow for total internal reflection of light within the prism, thus achieving the turning of optical paths or the deflection of images.
Roof Prism: It is a type of prism with two mutually perpendicular reflective surfaces, known as roof surfaces. It can add an extra reflection without changing the direction of the optical axis or the imaging direction within the principal plane, thereby meeting the requirement of object-image similarity.
