The utility model solves the technical scheme that its technical matters adopted: between light source and slide block; Place a microlens array; Lenticule in the microlens array is corresponding one by one with pin hole; Make the light of light emitted pass through each pin hole on the slide block, be radiated on the sample then through beam splitting behind the microlens array, focusing.Because lenticule is to the focussing force of light, the luminous flux that passes pin hole is improved, and has therefore improved the utilization ratio of light source; And reduced the parasitic light that slide block reflects simultaneously, reduce the parasitic light noise of scanner.
The utility model is as shown in Figure 1 to be comprised: light source 1; Illumination color filter 2; Illuminating lens group 3; Microlens array 4 has been arranged a plurality of lenticules 5 on it; Slider bracket 6; Drive motor 7; Dichroic beam splitter 8; Lighttight slide block 9 is being arranged a plurality of printing opacity pin holes 10 on it; Imaging lens group 11; Imaging color filter 12; Controller 13.
The purpose of the utility model realizes through following technical scheme: as shown in Figure 2, between illuminating lens 3 and light tight slide block 9, place microlens array 4 perpendicular to light path; The light of light source 1 emission arrives microlens array 4 by beam splitting behind over-illumination color filter 2 and illuminating lens 3, focused on respectively through the printing opacity pin hole 10 on the light tight slide block 9 by the light of beam splitting; Light tight slide block 9 is positioned on the focal plane of microlens array 4; Printing opacity pin hole 10 on the light tight slide block 9 is corresponding one by one with the lenticule 5 of microlens array 4, and the focus of the center of pin hole 10 and lenticule 5 overlaps.
The beneficial effect of the utility model is:
1, improves the utilization ratio of light source, strengthened the illumination level of sample.
2, reduce the parasitic light of slide block reflection, reduced ground unrest.
