Abstract
An incident light illumination apparatus for generating light and dark field illumination along an optical axis. The illumination apparatus is coupled to a stage arm of a microscope and a microscope tube is coupled to the illumination apparatus. An illumination stub (7) is located in the illumination apparatus along the optical axis between a light source (8) and an optical deflecting element (11). An aperture (13) passes through the stub from side-to-side for the interchangeable insertion of an insertion module (14,15). This insertion module contains at least two functional groups (I,II; III,II) which can be sequentially placed into the optical axis (9) and the functional groups consist of light attenuating (25) and/or light bounding (19,20,23,24,27) optical components, and additional means (28,29) for pivoting a center stop (30) into the optical axis (9).
