An optical instrument for forming and examining spectra (as that of solar light, or those produced by flames in which different substances are volatilized), so as to determine, from the position of the spectral lines, the composition of the substance.
A device that breaks incoming light down into spectral rays, so that one can see the exact wavelength constituents of the light.
An instrument that breaks up the white light from a star into its different colors.
An instrument allowing an observer to view the spectrum of a source of light.
An instrument that measures the individual wavelengths of light in a beam of light.
Device, such as a prism, which refracts white light and produces a spectrum which can be observed.
A device for dispersing radiation into a spectrum so that the component wavelengths can be observed
A device used to observe the spectrum.
optical instrument containing a prism or grating with appropriate lenses to permit direct viewing of the spectrum of a radiating source.
spectrometer. An instrument for measuring the spectrum of light or radiation.
An instrument used in gem identification.
A machine (instrument) for producing and observing spectra.
an optical instrument for spectrographic analysis
a device that lets us find out what things are made of
a device that separates light into its component colors
a device that splits a light beam into the different wavelengths contained in the beam
a device to measure wavelengths accurately using a diffraction grating or a prism to separate different wavelengths of light
a device used for splitting a beam of light or radiation into it's component parts to be studies
a device which measures the spectrum of light
a device which separates light by color (technically, by the wave-length of the photons)
a mechanical device for analysing light
an instrument used to generate a spectrum, namely, a dispersion of light into its constituent colors
an optical instrument for separating light into spectral lines and measuring the wavelengths and intensities of the different colors of light that emerge
a scientific instrument used to break up light into its various colors, much like a prism
a "spectrum-observing" instrument and a spectrometer is for "spectrum measurement"
a tool used to separate light into its different colors (wavelength frequencies)
Instrument used to view the absorption spectra of gemstones.
A device used for separating light into component colours for analysis.
is an instrument which separates light into its component wavelengths to determine the composition of the source of the light. Spectroscopes are used to study astronomical objects such as comets.
an instrument that uses a prism or diffraction to split light into a spectrum
Instrument used to view a light source so that it is split into its component colors.
An optical instrument designed to spread out light into the spectrum of its component colors.
Tool used to measure the spectrum of light which passes through a gem. Useful in determining the identity of a gem.
A spectroscope is a scientific instrument that breaks up the light from a star into its component colors in order to identify which elements are present in that star.
An optical instrument which spreads a beam of electromagnetic radiation into a spectrum of different wavelengths for visual inspection.
an optical instrument used by scientists to analyze what elements are present on the sun; it can also be used to detect motion and the speed of motion of gaseous objects.
An instrument that separates light into it's different wavelengths. It is the instrument that permits us to identify the elements in a particular light source.
A scientific instrument that breaks light into its component wavelengths for measurement.
An instrument for examining spectra; also a spectrometer or spectrograph if the spectrum is recorded and measured.
An instrument that separates visible light into its various wavelengths. Each wavelength corresponds to a specific color in the spectrum.
A spectroscope is an instrument that is used to identify gemstones. It works by determining the light waves that a stone absorbs; different stones absorb different wavelengths of light.
An apparatus to effect dispersion of radiation and visual display of the spectrum obtained.
