mass spectroscope
An instrument that uses electromagnetic fields to sort out the relative masses of atoms and molecules.The same way an optical spectroscope uses a prism to separate light into its various wavelengths,...
mesoscope
In the field of optics and imaging, a mesoscope refers to an optical instrument that is designed to observe and capture images at intermediate scales, falling between microscopic and macroscopic...
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...
micrograph
A graphic reproduction of an object formed by a microscope or another optical system. Also an instrument used to make tiny writing, etching, or engravings.
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...
mirror blank
A mirror blank refers to the initial piece of material from which a mirror is made. It is typically a flat or slightly curved piece of glass or other substrate that serves as the starting point for...

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...
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...
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...
multimeter
->
optical multimeter
An instrument that measures several optical parameters, such as optical power and wavelength, with a single measurement input.
