Abstract

A modular device (5) for an optical device, such as a microscope (1), is described. This device has adjacently disposed mountings (24a, 24b) for optical systems which can be introduced alternately into the illumination beam path (2) or optical axis (2a) of the microscope by use of a pull rod (11) provided on the modular device (5). At least one of the mountings (24a) is capable of being uncoupled from the pull rod (11), so that the relative spacing of two mountings (24a, 24b) can be altered. Additionally an optical element (17), for example, a compensating plate disposed in the microscope, can be pivoted into the optical axis (2a). By using the modular device (5), a rapid switch-over from traditional methods of microscopy to, for example, investigations utilizing fluorescence microscopy and vice versa, without any effect on the image section and the image sharpness, is possible without undertaking adapting operations or reconstructing the microscope.
