ABSTRACT:
A transmission type illumination equipment for microscopes comprising a condenser lens for high magnification level and an aperture stop arranged in the vicinity of the front focal point of said condenser lens for high magnification level which are so arranged as to be replaceable with a condenser lens for low magnification level and an aperture stop arranged in the vicinity of said condenser lens for low magnification level respectively. Said illumination equipment for microscopes is so adapted as to form an image of the light source at the position of a corresponding aperture stop when it is switched for illumination between high and low magnification levels, thereby assuring illumination in favorable conditions from ultra-low to high magnification levels.
