  2. Prism spectrometer - Wikipedia

    en.wikipedia.org/wiki/Prism_spectrometer

    A prism spectrometer is an optical spectrometer which uses a dispersive prism as its dispersive element. The prism refracts light into its different colors ( wavelengths ). The dispersion occurs because the angle of refraction is dependent on the refractive index of the prism's material, which in turn is slightly dependent on the wavelength of ...

    en.wikipedia.org/wiki/File:Double_Amici_prism...

    A double-Amici prism, showing the apex angles (and ) of the three elements, and the angles of incidence and refraction ′ at each interface. The deviation angle of the ray transmitted by the prism is shown as δ {\displaystyle \delta }

  4. Dispersive prism - Wikipedia

    en.wikipedia.org/wiki/Dispersive_prism

    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.

  5. Wedge prism - Wikipedia

    en.wikipedia.org/wiki/Wedge_prism

    The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from the prism.

    A triplet prism, showing the apex angles (, , and ) of the three elements, and the angles of incidence and refraction ′ at each interface. The deviation angle of the ray transmitted by the prism is shown as δ {\displaystyle \delta } .

  8. Refractometer - Wikipedia

    en.wikipedia.org/wiki/Refractometer

    Schematic setup of an automatic refractometer: An LED light source is imaged under a wide range of angles onto a prism surface which is in contact with a sample. Depending on the difference in the refractive index between prism material and sample the light is partly transmitted or totally reflected.

  9. Prism (optics) - Wikipedia

    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.
