Condensers 0.53 S23 and 0.90 S1

With the illumination column tilted to the back, insert the condenser holder (15.4) into the dovetail guide of the illumination column from below (15.2). The condenser height adjustment should point to the left. Adjust the height of the condenser holder until its upper edge coincides with the condenser height marking S23 or S1 on the illumination column (16.1), depending on the condenser top used. Secure the condenser hold- er with the hexagonal screwdriver and clamp screw (15.5). Mount the base part of the condenser with the dovetail guide (8.6) to the slide change mechanism (7.1) of the condenser holder (17). The condenser top should point downwards and the aperture diaphragm control towards the front (17.3). Slacken the clamp screw (17.5) and push the condenser back as far as the stop. Retighten the clamp screw (17.5) slightly.
