ABSTRACT:
The invention relates to an epi-illumination optical system for microscopes which relies upon a Köhler illumination system using a collective lens array, having simplified adjustment function capable of adjusting the image position of a light source to the back focal position of each microscope objective lens in operable association with microscope objective lens replacement. The invention provides an epi-illumination optical system for microscopes, with an objective lens serving as a condenser lens, which comprises a light source, a collimate lens, and a lens array. The epi-illumination optical system further comprises a projection optical system adapted to project an image of light source formed by collective lens array. The projection optical system comprises a partial optical system movable in an optical axis direction, so that the imaging position for the image array of light source is adjustable to the back focal position of the objective lens.
