  1. Optical spectrometer - Wikipedia

    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 …

  2. Spectrometers, monochrometers and spectrographs - Horiba

    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.

  3. How Does a Spectrograph Work? [Infographic] - Scientific American

    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...

  4. Spectrographs – spectroradiometers, multi-channel photodetector

    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 …

  5. Spectrometer, Spectroscope, and Spectrograph - SPIE

    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.

  6. Spectrographs - an overview | ScienceDirect Topics

    A spectrograph is defined as an optical device that utilizes dispersive elements, such as gratings or prisms, to separate broadband light into its constituent wavelengths, enabling the capture of high …

  7. SPECTROGRAPH Definition & Meaning - Merriam-Webster

    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.

  8. Spectrograph and Spectroscopy | ESA/Hubble | ESA/Hubble

    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 …

  9. Spectrograph | physics | Britannica

    Newton noted the interesting way in which a piece of glass can break up light into different bands of colour, but it was not until 1814 that the German physicist Joseph von Fraunhofer discovered the …

  10. What are optical spectrographs used for- Oxford Instruments

    A spectrograph is an instrument used to separate and measure the wavelengths present in Electromagnetic radiation and to measure the relative amounts of radiation at each wavelength. In …
