µmicro- the SI metric unit prefix, which represents one millionth, i.e. 10-6, of a given unit
µmmicron (also referred to as the micrometer)- which represents one millionth, i.e. 10-6 of the SI unit for length that is the meter.
mmeter;mass;milli- m is the standard unit symbol for length in the International System of Units (SI). 1 meter is equivalent to 3.28 feet. m is also the standard symbol for mass; m is also the standard SI metric unit prefix milli- which represents one thousandth i.e. 10-3, of a given unit.

mAsmilliamperes-second - unit measure of electric charge acquired when multiplying the electric current in milliamperes (one thousandth or 10-3 of the standard unit for electric current the ampere) by the time in seconds. It is commonly used to describe the length of time that electrons are produced or passed through a given circuitry.

MAUmedia access unit — A media access unit (MAU) is a unique device utilized to connect token ring devices from multiple network stations into a star topology. There are two types of MAUs, passive and active. Passive MAUs are powered from their network connections while active MAUs are powered electrically from an external source.

Mbmegabit — The megabit (also expressed as Mbit) is equivalent to one million (or 106) of the standard unit for digital information storage in telecommunications which is the bit.
MBmegabyte — The megabyte (also expressed as Mbyte) is equivalent to one million (106) of the standard unit for digital information storage in computing which is the byte.
MB/smegabytes per second — The megabyte per second (not to be mixed up with the Mb/s -- megabits per second) is a unit of data transfer rate equivalent to one million (106) bytes per second over a given information network.
Mb/smegabits per second — The megabit per second (not to be mixed up with the mbit/s – millibit per second, or Mbitps- megabit picosecond) is a unit of data transfer rate equivalent to one million (or 106) bits per second over a given information network.
MBEmolecular 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.
Mcmegacycles
Mc/smegacycles per second — Megacyces per second is an oscillation rate equivalent to one million (or 106) of the standard unit of a single optical period over a second which is an optical cycle.
MCAmicrochannel analyzer
mcdmillicandela — The millicandela is equivalent to one thousandth (or 10-3) of the standard unit of luminous intensity that is the candela, which is the power emitted by a given light source in a particular direction.
MCFmutual coherence function — The mutual coherence function is a complex quantity that is the time-averaged value of the cross correlation function of a light field at two points within an aperture with a time delay that relates the path difference to the point of observation of the interference fringes. The mutual coherence function is the key function in coherence theory and the study of partially coherent light.
MCMmodulation contrast microscopy; multichip module — modulation contrast microscopy is a unique illumination technique that enhances contrast in an imaging microscope by converting optical gradients into variations in light intensity. Modulation contrast microscopy is found most commonly in live cell imaging, polarization microscopy, phase contrast, and oblique illumination of stained, unstained and birefringent specimens. A multichip module is an electronic packaging system where multiple discrete electronic components (integrated circuits, semiconductor diodes, etc.) are packaged in various ways onto a single substrate.

MCTmercury cadmium telluride — Mercury cadmium teluride (HgCdTe) is a specific alloy combination that allows one to obtain any optical absorption bandgap of the material between 0 and 1.5 electron volts (eV) making it completely transparent at photon energies and wavelengths below the energy gap in the infrared.
MCVDmodified chemical vapor deposition
MCZmagnetic Czochralski process — Introduction of an external magnetic field in the Czochralski melting process for crystal growth in order to influence the flow and dampen the amplitudes of the melt oscillations that occur in the process. This is accomplished when the external magnetic field generates an electric field inside the melt, which further induces an internal magnetic field in the now electrically conducting melt. The amplitudes of the now induced electric and magnetic fields can be controlled by the strength of the external magnetic field allowing control of the MCZ process.
MDLminimum detection limit (MDL) — In chemistry, the minimum detection limit is the lowest concentration of a chemical substance that can be discerned from the absence of that substance.
MDMmetal-dielectric multilayer (MDM) — Periodic nanofilm structures for optical mode confinement and tunneling of resonant surface plasmons.

MELmany-element laser; maximum excess loss (MEL) — the many element laser is a laser unit that consists of N like elements of active materials for support with the mode selection of the laser output. The mode selection properties of a many element laser have been experimentally exploited with as many as 10 like elements.
Maximum excess loss is the maximum power lost within a give system (typically a fiber optic communication system) including scattering, dispersion, absorption and coupling loss.
