The lower lens can be slid out of the optical path, either to the right or to the left. When it
is in the optical path, the numerical aperture is 0.25, suited for the orthoscopic observation and
when it is out of it, the numerical aperture is 1.2, suited for conoscopic observation.
The polarizer can be rotated through 90° by means of a lever; the rotating scale is divided
into 5° calibration. When the polarizer is clicked into position at 0°, its oscillation is longitudinal.
The iris diaphragm can be adjusted by means of a lever.
NOTE; When attaching the condenser to the body, the registration pin of the condenser must
first be fitted into the sleeve groove. The condenser is then pushed up as far as possible and
clamped to the body. Otherwise, the oscillation of the condenser will be erratic. The condenser
sleeve is so designed that dark field condensers and phase contrast condensers produced by other
makers can be attached to the POS.
