An instrument for separating and recording the spectral components of light. Contemporary instruments use electronic cameras to record the spectra.
An instrument for recording the spectra of astronomical bodies or other sources of light.
An instrument for photographing spectra eg the electromagnetic spectrum.
Device used to observe and record spectral changes.
An astronomical instrument placed on a telescope that diffracts light with a grating or prism into its component colors. The different colors, or wavelengths, can then be analyzed for chemical absorption or emission lines. Usually, a CCD camera records the spectrum, transmits the image to a computer that displays it for astronomical analysis.
basically the same as the spectroscope except that the eyepiece is replaced by a photographic plate for recording the spectrum.
A spectroscope that measures wavelengths of light (spectra) and then displays the data as a graph. UVIS is an imaging spectrograph, which means it can also display the points of the graph as a picture (see Imaging Sepctrosopy).
a spectroscope by which spectra can be photographed
a photographic record of a spectrum
a device that spreads out the light gathered by a telescope so it can be analyzed to determine the properties of celestial objects such as chemical composition, temperature, velocity and magnetic fields
an astronomical instrument attached to a telescope
an instrument that records spectral intensity information in one or more wavelengths of energy and then outputs the data in the form of a graph
an instrument that separates incoming light according to its wavelength and records the resulting spectrum in some detector
an instrument that spreads out light into its spectral components ( i
an instrument that transforms an incoming time-domain waveform into a frequency-domain spectrum, or generally a sequence of such spectra
an instrument which separates different wavelengths of light so they can be measured independently
A spectrograph is an instrument used to obtain and record an astronomical spectrum. The spectrograph splits or disperses the light from an object into its component wavelengths so that it can be recorded then analysed. Modern multifibre spectrographs as the 2dF on the AAT allow hundreds of individual spectra from stars or galaxies to be obtained simultaneously.
An instrument used to disperse or separate the light into all its wavelengths which allows quantitative measurements of intensity to be made. As an instrument on a telescope, the spectrograph obtains the spectrum of the light from the astronomical objects. Each spectrum contains a wealth of information. For instance, each chemical element has a distinctive spectrum, which varies with temperature. By analyzing the spectrum of a star astronomers can learn about its chemical composition, its temperature.
used interchangeably to refer to either (1) the instrument used in acoustic phonetics to provide a visual graph of acoustic features representing a given utterance or (2) the graph itself.
an instrument for photographing a spectrum
an instrument that splits light or other electromagnetic radiation into its individual wavelengths, or spectrum, and records the result photographically.
A technology that measures how a given object responds to frequencies within the light spectrum. Objects can be identified and their properties visually clarified by use of this technology.
An instrument with one slit that uses photography to obtain a record of a special range simulaneously.
The image of the electromagnetic spectrum produced by a spectroscope.
A spectrograph is an image of the electromagnetic spectrum of a light source. Spectrographs identify which elements are present in that star.
Modification of a spectroscope in which the spectrum is photographed or recorded electronically.
An instrument that spreads light or other electromagnetic radiation into it's component wavelengths ( spectrum), recording the results photographically or electronically.
An instrument that spreads out the light gathered by a telescope so that it can be analyzed to determine many different properties of celestial objects. These properties include the chemical composition and abundance of different elements, temperature, radial velocity, rotational velocity, and magnetic fields.
instrument that allows to register the spectrum of a source, after the resolution of it.
A device that separates light by wavelength (color) in order to produce a spectrum that allows for the identification of elements within the light source. We have a spectrograph attachment for the CCD camera from SBIG.
An instrument that spreads electromagnetic radiation into its component frequencies and wavelengths for detailed study at each individual frequency and wavelength. ,H3SPACTROSCOPIC PARALLAX--The third rung of the distance ladder, whereby a star's spectrum is used to estimate its absolute brightness and thus its distance.
A spectroscope for photographing or producing a representation of a spectrum (most commonly taken of light or x-rays).
spectroscope with a photographic or other recording device to capture an image of the entire spectrum, or portions thereof, at one instant in time.
An instrument that spreads electromagnetic radiation into its component frequencies and wavelengths for detailed study. A spectrograph is similar to a prism, which spreads white light into a continuous rainbow.
