It is an instrument used to measure properties of light. It has many uses. find out more here http://en.wikipedia.org/wiki/Spectrometer
spectrometer
A mass spectrometer is a device used to determine atomic masses by separating and measuring the mass-to-charge ratio of ions. By analyzing the deflection of ions in a magnetic or electric field, the mass spectrometer can provide accurate measurements of atomic masses.
A spectrometer is used to measure different properties of light. Normally one is given a specific wavelength for the light measured when using this instrument.
A Raman spectrometer is a tool that is used for measuring low frequency modes such as vibrations or rotations. It is used mostly in chemistry although it is also used in physics to measure temperature.

Spectrometer
The vernier constant of a spectrometer is the smallest division on the scale that can be read. It is used to determine the angular separation between spectral lines.
A spectrometer measures the intensity of light at different wavelengths. By analyzing the spectrum of light emitted or absorbed by a sample, a spectrometer can provide information about the chemical composition, structure, or physical properties of the sample.
A gamma radiometer or a gamma spectrometer.

A spectrometer is a scientific instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. The least count of a spectrometer is the smallest change in wavelength or frequency detectable by the instrument. To take measurements with a spectrometer, you would typically calibrate the instrument using known standards and then analyze the light source you are interested in by measuring its intensity at different wavelengths or frequencies.
