Abstract

The present invention concerns a microscope and an illumination device for a microscope that ensure optimal illumination in the standard (10×–100×), scanning (1.6×–5×), and macro (1×–1.6×) ranges. The illumination system comprises only one condenser head that can be switched in or out and that can optimally illuminate the entire range from 1× to 100×, and a movably arranged focusing lens that ensures optimal adaptation of the illumination to the entrance pupil for all ranges.
