An optical scanner for light detection and color ratiometric measuring for use in apparatus to sort small particles such as seed and beans which are projected or propelled through the scanner at relatively high speeds to be scanned on all sides by a narrow light plane and viewed by a plurality of photoelectric devices. Several lamps are used in conjunction with cylindrical lenses to produce a substantially uniform collimated light plane perpendicular to the path of the particles. The lamps and lenses are interspersed with the photoelectric devices such that light reflected from the portion of the particle being scanned is detected by the photoelectric devices which are responsive to selected wavelengths and which responses are separately fed to an external electronic circuit for processing according to spectral responses such that said responses can be measured individually or compared with each other to determine certain color characteristics of the particle being scanned.
