Abstract
A produce data collector which includes a spectrometer which minimizes noise from scattered light and from wavelengths outside the operating range of the spectrometer. The produce data collector includes a light source for illuminating a produce item. The spectrometer obtains spectral information about the produce item in incoming reflected light from the produce item and includes a linear variable filter, a photodetector adjacent the linear variable filter, and an optical slit member above a primary surface of the linear variable filter which has a slit with a width sufficient to minimize scattering of the incoming light by interior surfaces of the linear variable filter. The produce data collector may additionally include a filter, such as an infrared filter.
