  2. Diffraction grating - Wikipedia

    en.wikipedia.org/wiki/Diffraction_grating

    A very large reflecting diffraction grating An incandescent light bulb viewed through a diffractive effects filter. Diffraction grating. In optics, a diffraction grating is an optical grating with a periodic structure that diffracts light, or another type of electromagnetic radiation, into several beams traveling in different directions (i.e., different diffraction angles).

  3. Polarizer - Wikipedia

    en.wikipedia.org/wiki/Polarizer

    The Sénarmont prism is air spaced, unlike the Wollaston and Rochon prisms. These prisms truly split the beam into two fully polarized beams with perpendicular polarizations. The Nomarski prism is a variant of the Wollaston prism, which is widely used in differential interference contrast microscopy .

  4. Pavement light - Wikipedia

    en.wikipedia.org/wiki/Pavement_light

    Solarized pendant prisms, showing a gradient in the solarization. The glass in many old pavement lights is now either purple or straw-colored. This is a side-effect of the manufacturing process. Pure silica glass is transparent, but older glass manufacture often used silica from sand, which contains iron and other impurities. [29]

  5. Retroreflector - Wikipedia

    en.wikipedia.org/wiki/Retroreflector

    A typical surveying prism with back target. In surveying, a retroreflector—usually referred to as a prism—is normally attached on a surveying pole and is used as a target for distance measurement, for example, a total station. The instrument operator or robot aims a laser beam at the retroreflector. The instrument measures the propagation ...

  6. Prism (geometry) - Wikipedia

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

    A uniform prism or semiregular prism is a right prism with regular bases and all edges of the same length. Thus all the side faces of a uniform prism are squares. Thus all the faces of a uniform prism are regular polygons. Also, such prisms are isogonal; thus they are uniform polyhedra.

  7. Total internal reflection - Wikipedia

    en.wikipedia.org/wiki/Total_internal_reflection

    Fig. 1: Underwater plants in a fish tank, and their inverted images (top) formed by total internal reflection in the water–air surface. In physics, total internal reflection (TIR) is the phenomenon in which waves arriving at the interface (boundary) from one medium to another (e.g., from water to air) are not refracted into the second ("external") medium, but completely reflected back into ...
