A turret condenser for microscopes is equipped with two turrets which are capable of interposing combinations of numerous types of optical elements on the optical axis and rotatably arranged in overlapped positions in the vicinity of the pupil of a condenser lens. Most of the optical elements are removably accommodated in each of the turrets. This turret condenser makes it possible to perform microscopy in various modes by simple operations.
