• On upright microscopes, the condenser is located beneath the stage and serves to gather wavefronts from the microscope light source and concentrate them into a cone of light that illuminates the specimen with uniform intensity over the entire view-field. Inverted (tissue culture style) microscopes mount the condenser above the stage and specimen on a frame pillar. It is critical that the condenser light cone be properly adjusted to optimise the intensity and angle of light entering the objective front lens. Each time the objective is changed, a corresponding adjustment must be performed on the condenser to provide the proper light cone to match the numerical aperture of the new objective. The size and numerical aperture of the light cone is determined by adjustment of the aperture diaphragm as outlined in this tutorial. After passing through the specimen, the light diverges into an inverted cone with the proper angle to fill the front lens of the objective.
