Standard 25 ICSB 40-029 e 01/98 2-72.7 Attachment of condensers2.7.1 Attach condenser 0.9 Z Unscrew both centering screws (2-7/3) on thecondenser carrier (2-7/2) until the condenser 0.9Z (2-7/9) can be easily inserted in the condensercarrier. Insert condenser 0.9 Z (2-7/9) in the condensercarrier (2-7/2) in such a way that, firstly, thedovetail of the condenser is pressed againstspring pin (2-7/1) in the condenser carrier and,secondly, the aperture diaphragm lever (2-7/8)can be conveniently operated from the front. Tighten both centering screws (2-7/3) on thecondenser carrier (2-7/2) until they engage inthe dovetail and keep the condenser (2-7/9) inposition.The Ph 2 phase stop carrier (2-7/4) must bemounted as follows: Screw locking screw (2-7/6) into the left drilledhole (2-7/7) on the underside of the condensercarrier. The locking screw keeps the Ph 2 phasestop carrier in its functional position. Then screw Ph 2 phase stop carrier (2-7/4) intothe drilled hole (2-7/5) on the underside of thecondenser carrier.2.7.2 Attach phase contrast condenser IIZ 0,9 Ph 1, 2, 3 and D (0.6/0.9)With the exception of the orientation in thecondenser carrier (2-7/2), the phase contrastcondenser II Z 0.9 is inserted in the Standard 25 ICSin the same way as the above condenser 0.9 Z. Insert condenser II Z 0.9 (2-8/1) in the condensercarrier (2-7/2) in such a way that knob (2-8/2)points to the observer.Fig. 2-7 Attachment of condenser 0.9 ZFig. 2-8 Attachment of phase contrastcondenser II Z 0.9 Ph 1, 2, 3 and D(0.6/0.9)
