  • noun a measurement of the ability of an optical system to detect fine black lines on a white background, given as the number of lines per millimetre


  • In spectroscopy, the ability to separate or differentiate between measured parameters of nearly equal magnitude or value. For example, the separation of particles with nearly identical mass by a mass spectrometer, or the differentiation of spectral lines of nearly equal wavelength by a spectroscope.
