ABSTRACT:
A system to obtain a high resolution image of a relatively large sample (11) for viewing by a researcher includes a rectangular holder (20) that receives a microscope slide (10) and which includes a glass filter (40) that reduces the amount of illumination of the sample without reducing the Kelvin light temperature, and a scanner (22) that receives the holder (20) and produces electrical signals which are fed to the hard drive of a computer (23) where a high resolution image of the sample is displayed on the monitor (24). One embodiment of the invention (FIGS. 5-8) utilizes a separate high intensity light source (60A) for the scanner (22A) for illuminating opposed surfaces of the slide (10A ), and a fiber optic light pipe (66A) connects the high intensity light source to the holder (20A ) within the scanner (22A ).
