Two small knurled-head knobs tighten to hold on the flip-up lid/mirror. Under this is a condenser with iris which fits into a short threaded drawtube for it. The condenser drawtube, must be raised by unscrewing it to allow clearance for slides and for focusing the condenser on the specimen. It must be lowered to be able to close the lid/mirror. The condenser has a built-in iris diaphragm. The iris is adjusted by turning the condenser, a tiny knob(red arrow) controlling it protruding to make contact with the side of the microscope as the knurled ring is turned.
