Abstract: PCT No. PCT/DE93/00865 Sec. 371 Date Jun. 27, 1994 Sec. 102(e) Date Jun. 27, 1994 PCT Filed Sep. 15, 1993 PCT Pub. No. WO94/07168 PCT Pub. Date Mar. 31, 1994.An epi-illumination system for microscopes is described, which contains an epi-illumination module (18) that consists of a Smith-splitter with an integrated telescope system (14). The telescope system (14) corrects in the sense of "Shift-Optics" differences in length that appear when switching from a modularly-designed 45 degree neutral splitter (20) to a Smith-splitter containing module (18). The arrangement of the two lenses in the telescope system (14) is such that the positive member (15) is directed towards the mirror (4) of the Smith-splitter and the negative member (16) is directed towards the light source (6). Alternatively it is also possible to install a telescope system with an opposite lens arrangement in a module (19), containing a 45-degree neutral splitter, if this is exchanged for a Smith-splitter containing module, so that the negative member (16) is directed towards the 45-degree neutral splitter (20) and the positive member (15) is directed towards the light source (6).

Date Aug. 17, 1995An exchangeable condenser system for a phase-contrast illuminating system (12) for microscopes has a plurality of different light rings (5), arranged on a nosepiece plate (4), assigned to the condenser optical system (6). The condenser optical system (6) can be exchanged independently of the light rings (5), the focal lengths Fn of the exchangeable condenser optical systems (6) being selected relative to one another in the ratio Fn=F0*Xn and the average diameters Dn of the light rings (5) being selected relative to one another in the ratio Dn=D0*Xn, where X>0, n=0,1,2,3, . . . .
