A ray trace through a prism with apex angle α. Regions 0, 1, and 2 have indices of refraction, , and , and primed angles ′ indicate the ray's angle after refraction.. Ray angle deviation and dispersion through a prism can be determined by tracing a sample ray through the element and using Snell's law at each interface.
Perger prism a development based on the Porro–Abbe prism, projects image forward, rotated by 180° and displaced; Abbe–Koenig prism projects image forward, rotated by 180° and collinear (4 internal reflections [2 reflections are on roof plains]) Bauernfeind prism projects image sideways (inclined by 45°) Amici roof prism projects image ...
Material dispersion can be a desirable or undesirable effect in optical applications. The dispersion of light by glass prisms is used to construct spectrometers and spectroradiometers. However, in lenses, dispersion causes chromatic aberration, an undesired effect that may degrade images in microscopes, telescopes, and photographic objectives.

The left one uses an erecting prism whereas the right uses an erecting lens and a second image plane. a Objective lens b Field lens c Image erecting lens d Ocular lens e Lens of the observer's eye f Right-angled prism g Image ...
An interference filter guarantees the specified wavelength. Due to focusing light to a spot at the prism surface, a wide range of different angles is covered. As shown in the figure "Schematic setup of an automatic refractometer" the measured sample is in direct contact with the measuring prism. Depending on its refractive index, the incoming ...
Crown glass is a type of optical glass used in lenses and other optical components. It has relatively low refractive index (≈1.52) and low dispersion (with Abbe numbers between 50 and 85). Crown glass is produced from alkali-lime silicates containing approximately 10% potassium oxide and is one of the earliest low dispersion glasses .
Light separated into a spectrum by refraction through glass prism. Colour dispersion angles exaggerated for visualisation. Modern spectroscopy in the Western world started in the 17th century. New designs in optics, specifically prisms, enabled systematic observations of the solar spectrum.
In surveying, retroreflector prisms are commonly used as targets for long-range electronic distance measurement using a total station. Five arrays of optical corner reflectors have been placed on the Moon for use by Lunar Laser Ranging experiments observing a laser 's time-of-flight to measure the Moon's orbit more precisely than was possible ...
