Abstract
A microscope for virtual-slide creating system has a stage for holding the specimen, a transmitted-light illumination optical system for illuminating the specimen with transmitted light, an objective, a tube lens and an image capture unit. The objective is configured as a dry system of infinity-corrected type with an object-side numerical aperture of 0.8 or greater and a focal length for d-line rays in a range from 8 to 20 mm. The tube lens has a focal length in a range from 160 to 280 mm. The image capture surface of the image capture unit has a long side of 12 mm or longer and a pixel size (μm) satisfying the following condition:(μm)≦(0.61×0.59 (μ/m))/where a is the pixel size, and NA' is an image-side numerical aperture.
