Abstract: PCT No. PCT/DE95/00160 Sec. 371 Date Oct. 6, 1995 Sec. 102(e) Date Oct. 6, 1995 PCT Filed Feb. 8, 1995 PCT Pub. No. WO95/22072 PCT Pub. 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, . . . .
