Photonics Dictionary: M

Clear All Filters x film x M x
magnetic bubble film

An amorphous film in which cylindrical bubbles of reverse magnetization can be formed to follow circuit paths usually made by depositing magnetic metal strips on the film surface. It is used in...

microfilm camera

A camera used to reduce originals onto film for easy storage. There are two basic types: one in which the film is fixed during exposure, and one in which the film is exposed while moving past an...

microfilm equipment

Two essential pieces of equipment used in connection with the microfilming process: a camera capable of producing, on film, large-scale reductions of almost any matter, printed, painted or...

microfilm reader

A device used to view microfilmed documents where the image on film is projected, in magnified form, onto a rear projection screen for viewing.

microfilm system

A camera copying system that can reduce originals onto 35- or 16-mm film for easy storage.

magnetic disc

A plastic disc coated with ferric oxide or other films on which data can be stored by selectively magnetizing areas of the surface.

magnetic enhancement

Plasma-enriched deposition or planar magnetic sputtering that offers increased deposition rates in optical thin-film production. This technology surpasses conventional and RF sputtering.

masks for evaporation/deposition

In the context of thin film deposition processes such as evaporation or sputtering, masks are used to selectively deposit material onto substrates, creating patterns or structures with precise...

Matrix optics

The linear relationship between input and output optical fields for a given optical system or application that allows the use of a matrix and matrix algebra to define an optical system, or series of...

MBE

molecular beam epitaxy — A well-controlled thin film technique for growing films with good crystal structure in ultra high vacuum environments at very low deposition rates. MBE is also commonly used in the manufacture of semiconductor devices and solar cells.

MDM

metal-dielectric multilayer (MDM) — Periodic nanofilm structures for optical mode confinement and tunneling of resonant surface plasmons.

metallic coating

A thin layer of metal deposited on the surface of a substrate. The film may serve as a reflector, beamsplitter, neutral density filter or electromagnetic interference filter.

metallic mesh filter

An interference filter in which a very thin metal foil with a periodic array of square holes (inductive mesh) or a thin plastic substrate with an array of metal squares (capacitative mesh) is used as...

metric photography

The photographic recording of objects or events in a manner that allows quantitative information to be derived from the photograph. An example is the film made by a cinetheodolite in photographing a...

micro-optic gyroscope

A thin-film device that integrates optics and electronics on a single chip to provide a passive-ring resonator gyroscope capable of withstanding high g forces.

microdensitometer

The fundamental tool of microdensitometry, the microdensitometer is an instrument used for the precise measurement of microscopic optical densities (i.e. optical absorption) by detection of faint...

microfiche

A small card (10 x 15 cm) that has been treated with a photographic emulsion to record and store the microimages of documents and graphic information projected on it by a microfilm camera. A...

microphotograph

A photograph reduced to the microscopic scale and stored on a microfilm as seen with microfiches for the purpose of storing and archiving information.

microphotometer

An instrument capable of measuring the transmitted or reflected luminance from a very small area seen under a microscope. Microphotometers are the fundamental tools of microphotometry and are also...

microscope

An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the...

mirror coating

One or more thin-film layers of optical material deposited on a mirror blank/substrate in order to enhance the way that substrate reflects light. For example of optical materials/optical coatings...

molecular beam epitaxy -> epitaxy

A well controlled thin films technique for growing films with good crystal structure in ultra high vacuum environments at very low deposition rates. Epitaxy methods are well known for the growing of...

momentum transfer

In physics, momentum transfer is the amount of momentum transferred from one particle to another during particle collision or interaction. This phenomenon can be utilized in various areas of physics...

mosaic detector array

A group of photosensors arranged in a grid-like pattern covering the entire field of view, enabling them to record it all at once (as a camera records an image on film) rather than by scanning parts...

motion picture camera

A camera equipped with a lens and a long length of perforated film, the latter being moved intermittently between exposures by a pulldown claw or sprocket. A rotating shutter serves to cut off the...

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...

multiple lens camera

A camera that uses a rotating mirror to project sequential images onto lenses that are arranged in an arc. The reflected images can then be recorded on stationary film. By using an 8-mm frame format,...

Mylar

E.I. duPont's trade name for a polyester film. The most practical beamsplitter for use beyond the 15-µm wavelength because of its high efficiency. It exhibits high visible transmission, allowing...
