Technique and Procedure     Kohler Illumination     With your microscope focused under low power, hold a sharply pointed pencil or pen over the top of the light source at the bottom of your microscope. The point of the pencil should be at the center of the light source. Raise or lower the condenser until the shadow of the pencil point comes into focus through the oculars. The microscope is now "Kohlered" and is operating at maximal resolution. Always make sure that your microscope is Kohlered before making any critical examinations. Back |  Next
