Device and system for optically analyzing food products

A device for optically analyzing food products, the device comprising:

• a first imaging device sensitive to first wavelengths;
• a second imaging device sensitive to second wavelengths,
• one of the first imaging device and the second imaging device comprising:
• a line-scan camera configured to acquire images of food products in a human-visible wavelength spectrum, at a line in a food-path-facing direction,
• and an other of the first imaging device and the second imaging device comprising:
• a line-scan spectrometer configured to acquire spectroscopic images of the food products from the line in the food-path-facing direction;
• an optical filter configured to:
• convey the first wavelengths from the line to the first imaging device;
• and
• convey the second wavelengths from the line to the second imaging device;
• and
• a frame configured to align the optical filter and respective optical axes of the first imaging device and the second imaging device, relative to each other and the food-path-facing direction, such that the first imaging device and the second imaging device are optically aligned via the optical filter to image the line.
