Abstract
A spectroscope includes a light source providing a first and a second range of wavelengths, a dispersion unit to receive light and to output the first and second range of wavelengths at different angles, a positioning mechanism to position the dispersion unit such that the first range of wavelengths is applied to a first patch of a frame of film, to position the dispersion unit such that the second range of wavelengths is applied to the first patch but not the second patch and the first range of wavelengths is applied to the second patch at a second time, and to position the dispersion unit such that the second range of wavelengths is applied to the second patch, a first detector to detect responses from the frame of film from the first patch, and a second detector to independently detect responses from the frame of film from the second patch.
