Abstract
A spectroscopic device, which may be a handheld spectroscopic light source, which uses ambient light as a primary broadband light source, but which may be supplemented with an auxiliary light source to supplement band regions which may be deficient in the broad band source. The spectroscopic device makes use of a number of parallel control channels to monitor for sufficient light and to compensate for variations in the input light levels.
