- 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 spectroscopic analysis to identify materials [1]
- How Does a Spectrograph Work? [Infographic] - Scientific American
A spectrograph splits light into its component wavelengths First, light travels from a telescope through a small opening in the spectrograph to a collimating mirror that lines up all entering
- 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 A spectrograph includes some means, like an electronic detector, for recording the spectrum for analysis
- 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 Many astronomical observations use telescopes as, essentially, spectrographs
- 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 other words obtain and record the spectral content of light or its ‘spectrum’
- 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
- Spectrograph | physics | Britannica
Spectrography records the composition of light emitted by stars and other objects, the star image of the telescope being photographed through a diffraction grating, a device that disperses white light into constituent wavelengths Elements present in the star or the gas mantle surrounding it can… …or maps spectra is a spectrograph
- spectrographs – spectroradiometers, multi-channel photodetector
A spectrograph contains a fixed diffraction grating or some other kind of polychromator (a device which can spatially separate different wavelength components of light) and some kind of multi-channel photodetector (e g a photodiode array) for measuring the spectral light intensities
