macrophotograph

The photographic recordformed in macrophotography in which the size of the small nearby object at theimage plane is the same size or greater than the actual life size of theobject.

macrophotography

the photography of very close, and typically small objects with a magnification of approximately 1:1

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...

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.

multispectral photography

The use of narrow bandpass filters and special photographic emulsions to discern features of a surface that would not be easily recognizable with regular black-and-white or color photographic methods.

macro lens

A camera lens, used in macrophotography, that is designed and corrected to produce optimum definition of a nearby object when it is photographed at a magnification of approximately1:1.

magneto-optic readout device

A device using the Kerr effect to read back the signals from mechanically recorded tapes and discs. It consists of a light source, optical lenses to focus and direct the light beam, a pair of...

magneto-optic shutter

A type of high-speed photographic shutter that uses Faraday rotation to produce exposure times as fast as 1 microsecond. It consists of two polarizers, set with their planes of polarization at right...

mass spectrograph

A device that uses electromagnetic fields to separate electrically charged particles according to their masses. As a beam of charged particles is passed through a mass spectrograph, the result is a...

measuring eyepiece

Also known as an eyepiece micrometer. A microscope eyepiece that has a finely divided scale ruled or photographed on a section of transparent glass, and located in the focal plane. The dimensions of...

mercury arc

An electric arc that is formed in mercury vapor through which an electric current flows. The intensity of the illumination of the arc depends mostly on its design and the conditions under which it...

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...

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...

microflash

An extremely short, high intensity electronic flash of light, having a duration of about 1 x 10-6 s, used in photographing rapidly moving subjects.

microlens array

A microlens array is a grid-like structure composed of numerous small lenses, typically arranged in a regular pattern. Each individual lens in the array is referred to as a microlens. These...

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...

microscope, electron -> electron microscope

A device utilizing an electron beam for the observation and recording of submicroscopic samples with the aid of photographic emulsions or other short-wavelength sensors. With the electron microscope,...

minimum object distance

Minimum object distance, often abbreviated as MOD, refers to the closest distance at which a camera lens or optical system is capable of producing a sharp and focused image. In photography, this term...

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...

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...
