    en.wikipedia.org/wiki/Prism_(optics)

    Prism spectacles with a single prism perform a relative displacement of the two eyes, thereby correcting eso-, exo, hyper- or hypotropia. In contrast, spectacles with prisms of equal power for both eyes, called yoked prisms (also: conjugate prisms, ambient lenses or performance glasses) shift the visual field of both eyes to the same extent.

  4. Fresnel lens - Wikipedia

    en.wikipedia.org/wiki/Fresnel_lens

    In some lenses, the curved surfaces are replaced with flat surfaces, with a different angle in each section. Such a lens can be regarded as an array of prisms arranged in a circular fashion with steeper prisms on the edges and a flat or slightly convex center. In the first (and largest) Fresnel lenses, each section was actually a separate prism.

    Dispersive prism. Photograph of a triangular prism, dispersing light. Lamps as seen through a prism. In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow ). Different wavelengths (colors) of light will be deflected by the prism at ...

  6. Prism compressor - Wikipedia

    en.wikipedia.org/wiki/Prism_compressor

    A prism compressor is an optical device used to shorten the duration of a positively chirped ultrashort laser pulse by giving different wavelength components a different time delay. It typically consists of two prisms and a mirror.

  7. The Dark Side of the Moon - Wikipedia

    en.wikipedia.org/wiki/The_Dark_Side_of_the_Moon

    The design was inspired by a photograph of a prism with a beam of white light projected through it and emerging in the colours of the visible spectrum that Thorgerson had found in a 1963 physics textbook, as well as by an illustration by Alex Steinweiss, the inventor of album cover art, for the New York Philharmonic's 1942 performance of Ludwig ...
