condenser In microscopy, a hemispherical lens or series of lenses which helps to direct the optimum amount of light through varying sizes of aperture in objectives of various magnifications. Condensers are usually placed on the microscope below the stage, between the polarizer and the mineral specimen. In the control of illumination, the area of light from the illuminator is normally cut by the condenser to equal the field of view, thus minimizing glare due to interference from marginal light.
