81Color gel — See also: Photographic filter Many color gels organized, some in gel frames A color gel or color filter (UK spelling: colour gel or colour filter), also known as lighting gel or simply gel, is a transparent colored material that is used in… …
82Spectrophotometry — Spectrophotometer In chemistry, spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.[1] It is more specific than the general term electromagnetic spectroscopy in …
83Dichromatism — For colour blindness, see Dichromacy. Dichromatism (or polychromatism) is a phenomenon where the hue of the colour in materials or solutions are dependent on both the concentration of the absorbing substance and the depth or thickness of the… …
84Abbe sine condition — The Abbe sine condition is a condition that must be fulfilled by a lens or other optical system in order for it to produce sharp images of off axis as well as on axis objects. It was formulated by Ernst Abbe in the context of microscopes.The… …
85Anti-reflective coating — Many coatings consist of transparent thin film structures with alternating layers of contrasting refractive index. Layer thicknesses are chosen to produce destructive interference in the beams reflected from the interfaces, and constructive… …
86Neutral density filter — Neutral Density Filters are often used to achieve motion blur effects with slow shutter speeds In photography and optics, a neutral density filter or ND filter can be a colorless (clear) or grey filter. An ideal neutral density filter reduces… …
