Liquid-crystal display. The layers of a reflective twisted nematic liquid crystal display: Polarizing filter film with a vertical axis to polarize light as it enters. Glass substrate with ITO electrodes. The shapes of these electrodes will determine the shapes that will appear when the LCD is switched ON. Vertical ridges etched on the surface ...
Total station. A typical prism with back target. Used with survey and 3D point monitoring systems to measure changes in elevation and position of a point. A total station or total station theodolite is an electronic/optical instrument used for surveying and building construction.
E Ink Prism was announced in January 2015 at International CES and is the internal name for E Ink's bistable ink technology in a film that can dynamically change colors, patterns and designs with architectural products. [29] E Ink displays can also be made flexible. [30]
A Fresnel lens ( / ˈfreɪnɛl, - nəl / FRAY-nel, -nəl; / ˈfrɛnɛl, - əl / FREN-el, -əl; or / freɪˈnɛl / fray-NEL [1]) is a type of composite compact lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections.
This article lists computer monitor, television, digital film, and other graphics display resolutions that are in common use. Most of them use certain preferred numbers .
A polarizer or polariser is an optical filter that lets light waves of a specific polarization pass through while blocking light waves of other polarizations. [1] [2] [3] [4] It can filter a beam of light of undefined or mixed polarization into a beam of well-defined polarization, known as polarized light.
Chromatic aberration. In optics, chromatic aberration ( CA ), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point. [1] It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light.
In geometry, a prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy (rigidly moved without rotation) of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.
The refresh rate, also known as vertical refresh rate or vertical scan rate in reference to terminology originating with the cathode-ray tubes (CRTs), is the number of times per second that a raster-based display device displays a new image.
The micro-prism screen is adequate or usable down to f/4.5 lenses, however, the more useful split screen is capable of operating down to f5.6 before the center of the viewfinder becomes excessively dim.
