There are many different definitions of sensitivity. For StellarNet, we use the word sensitivity to mean the total system response of a spectrometer versus wavelength. This is a combination of the detector response, grating response, and any loss due to optics. StellarNet provides system sensitivity curves for its spectrometers. Ideally, spectrometers should have a wavelength region that has a balanced response across the wavelengths. A spectrometer that is extremely sensitive at 500nm, but not sensitive at other wavelengths, has limited uses
