MSM photodiode
A metal-semiconductor-metal (MSM) photodiode is a type of photodetector that consists of metal electrodes on a semiconductor material. Unlike the more common PIN photodiodes, which have a P-type and...

MTF curve -> modulation transfer function
Also called sine wave response and contrast transfer function. The modulation transfer function is the ratio of the modulation in the image to the modulation in the object as a function of frequency...
MTF optimization
Computerized lens design algorithm that permits the lens MTF characteristic to be included and controlled during the optimization process. MTF optimizations typically allow lens design users to...

multi-axis alignment
Multi-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 detector
A 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 camera
A 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 spectrometer
An 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 analyzer
A 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 hologram
A 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 mode
Used in computer design for optical systems with common parts and different applications.
multifiber cable
Fiber 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 joint
A fiber optic connector or splice that mates two multifiber cables, optically aligning all of the individual fibers simultaneously.
multifibers
An 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 lens
A 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...
multihaul transceiver
A multihaul transceiver is an optical transceiver module designed to support multiple network architectures or transmission technologies within a single compact device. It offers versatility and...
multijunction device
A 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 coating
A 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 lightguide
A fiber optic bundle split along its length with the ends of the fibers extending separately to illuminate different points with a single light source.
