Wherein, described laser light source part comprises the laser instrument combination in certain sequence of a plurality of output different wavelengths of light;
The laser instrument of described a plurality of output different wavelengths of light comprises red laser, green (light) laser, blue laser and infrared laser;
Comprise in the described laser beam merging apparatus along optical path direction be obliquely installed successively saturating red anti-greenly close the bundle sheet, the anti-indigo plant that reveals the green is closed bundle sheet and saturating infrared anti-visible combiner sheet;
Preferably, described laser instrument is solid-state laser, semiconductor laser or gas laser.
Compare with the light source that generally uses in the existing photometric sorting device, the utlity model has following advantage:
(1) adopt sharp combiner principle that the light of different wave length is propagated on same light path, for the diversification of rejecting object provides possibility.
(2) because the monochromaticjty and the directionality of LASER Light Source, laser can penetrate some material surface and interact with material, the principle of sorting extends to material internal structure and biological nature (such as fluorescent effect and near infrared absorption) from the material surface color, provides the rising space for improving sharpness of separation.
(3) object of reservation and reject laser that the wavelength location of the corresponding spectral response signal difference of object maximum selects respective wavelength as light source in the sorting material according to actual needs effectively improves detectable signal, reduces energy dissipation.
(4) this light source is by the material on the scan mode detection straight line, by LASER Light Source, and the laser beam merging apparatus, laser scanning device three parts are formed, and are simple in structure, compactness.
