An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in …

Dec 1, 2012 · First, light travels from a telescope through a small opening in the spectrograph to a collimating mirror that lines up all entering rays of light parallel to one another before they reach a...

A spectrograph splits light from an object into its component wavelengths so that it can be recorded and analyzed. It provides an image of defined bandwidth and wavelength.

A spectrograph is an instrument that separates incoming light by its wavelength or frequency and records the resulting spectrum in some kind of multichannel detector, like a photographic plate.

A spectrograph is an optical instrument used to measure the optical spectrum of a light source. It uses a dispersive element, like a fixed diffraction grating, to spatially separate different wavelength …

Spectrographs are instruments that are used to conduct spectroscopy. They provide scientists with the data they need to analyse the materials that make up stars, nebulae, galaxies and the atmospheres …

The meaning of SPECTROGRAPH is an instrument for dispersing radiation (such as electromagnetic radiation or sound waves) into a spectrum and recording or mapping the spectrum.
