multi-axis alignmentMulti-axis alignment refers to the process of aligning or adjusting components or systems in multiple spatial dimensions or axes. In various technical and engineering contexts, achieving precise...
multianode microchannel array detectorA photon-counting instrument for use in both space-borne and ground-based photometric and spectroscopic instrumentation. This style of detector is composed of opaque photocathodes for photon to...
multiband cameraA group of four cameras loaded with different combinations of filters and film (one is usually an infrared color film) to permit the recording of the same subject in four separate regions of the...
multichannel direct-reading spectrometerAn instrument that contains a spectrograph with a grating in which an array of slits, in place of a photographic plate, is arranged according to the lines of the sample to create an illustration of...
multichannel spectral analyzerA spectrometric instrument that detects radiation simultaneously in multiple channels, sorts it spectrally from the deep ultraviolet to the infrared, digitizes the information and stores it for...
multicolor hologramA hologram formed by reconstruction of multicolor wavefronts. The system used to produce the hologram is designed to combine the different colored wavefronts of the separate illuminating sources, and...
multiconfiguration modeUsed in computer design for optical systems with common parts and different applications.
multifiber cableFiber optic cable bearing many fibers independently sheathed and capable of carrying unrelated signals. They often surround a central strength member, and can be either loose- or tight-buffered. One...
multifiber jointA fiber optic connector or splice that mates two multifiber cables, optically aligning all of the individual fibers simultaneously.
multifibersAn array of optically distinct fibers that are fused into one strand. They are used to keep the resolution efficiency of the smaller, single fibers and eliminate difficulty in handling. Their...
multifocal lensA lens with internally adjustable elements to produce a range of focal lengths. Unlike a true zoom lens, a multifocal lens must be refocused each time the focal length is changed. See variable-focus...
multijunction deviceA photovoltaic device that consists of multiple p-n junctions to produce a greater efficiency when in use than that of traditional single junction devices. A multijunction device is unique because...
multilayer coatingA coating made up of many layers of material having alternating high and low refractive index. In this way, it is possible to produce coatings with a great variety of properties. These may be...
multileg lightguideA fiber optic bundle split along its length with the ends of the fibers extending separately to illuminate different points with a single light source.
multilineDescribing a laser that emits simultaneously at more than one wavelength.
multiline laser systemA multiline laser system refers to a type of laser that is capable of emitting multiple discrete wavelengths or spectral lines simultaneously. Unlike single-line lasers, which produce radiation at a...
multimeter -> optical multimeterAn instrument that measures several optical parameters, such as optical power and wavelength, with a single measurement input.
multimodality imagingA technique that combines two or more imaging processes in order to minimize the disadvantages within each of the contributing processes. In medical applications, combining multiple modalities...
multimode distortionIn an optical waveguide,- typically a multimode fiber - the distortion resulting from differential mode delay, i.e. axial rays (modes), with the shortest path length, will have the shortest...
