| Word | Definition |
|---|---|
| interference filternoun | An optical filter in which the wavelengths that are not transmitted are removed by interference rather than by absorption or scattering. |
| dichroic filter | — |
| polarizernoun | (physics) Any device that produces polarized light. |
| optical coating | An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. |
| spatial filter | A spatial filter is an optical device which uses the principles of Fourier optics to alter the structure of a beam of light or other electromagnetic radiation, typically coherent laser light. |

| dispersive 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). |
| optical instrument | An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties. |

| diffusernoun | A device designed to diffuse a scent efficiently. |
| diffraction gratingnoun | (physics) a surface having many closely spaced lines or slits; used to produce optical spectra by mutual interference |
| optical telescopenoun | An instrument, used both for recreational and scientific purposes, which provides a magnified view of distant objects by collecting and focusing light by means of mirrors and/or optical lenses. |
| neutral-density filter | In photography and optics, a neutral-density filter, or ND filter, is a filter that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition. |
