Generally the '''condenser''' is placed in its highest position or just slightly lower. At low magnification objectives (mainly 4x and 10x objectives), the opening of the condenser (or iris) diaphragm should be wide open. For high-dry (40x) and oil-immersion objectives (100x), the diaphragm should be closed slowly while looking at a sharply focused section until the level of illumination is just slightly reduced, in order to attain optimal contrast and resolution.<ref>{{cite web|url=https://histologylab.ctl.columbia.edu/HistologyLabManual.pdf|title=Histology Laboratory Manual, Vagelos College of Physicians & Surgeons Columbia University|author=Patrice F Spitalnik|accessdate=2021-09-20}}</ref> | Generally the '''condenser''' is placed in its highest position or just slightly lower.
