A dispersive prism is an optical device that uses refraction to split white light into its spectral components (the colors of the rainbow). Learn about the principle, types, history and applications of dispersive prisms, and how they differ from diffraction gratings and mirrors.
In a roof prism without a phase-correcting coating, s-polarized and p-polarized light each acquire a different geometric phase as they pass through the upper prism. When the two polarized components are recombined, interference between the s-polarized and p-polarized light results in a different intensity distribution perpendicular to the roof ...
Dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency, causing different colors of light to refract at different angles. Learn about material dispersion, waveguide dispersion, group-velocity dispersion, and their applications and effects in optics and wave propagation.
Learn about the types and applications of anti-reflective coatings, also known as antiglare or anti-reflection coatings, that reduce reflection and improve light transmission. Find out how they work, what materials are used, and how they affect color and contrast.
Optical glass is a type of glass suitable for optical systems such as lenses, prisms or mirrors. It contains additives to modify its optical or mechanical properties, such as refractive index, dispersion, transmittance and thermal expansion.
1: Imaging by a lens with chromatic aberration. 2: A lens with less chromatic aberration. In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. [1]
The word optics is derived from the Greek term τα ὀπτικά meaning 'appearance, look'. [1] Optics was significantly reformed by the developments in the medieval Islamic world , such as the beginnings of physical and physiological optics, and then significantly advanced in early modern Europe , where diffractive optics began.
A familiar dispersive prism. An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular ...
