Detailed explanation-1: -Use the diaphragm control lever to adjust the amount of light reaching the speciment, thus adjusting contrast of the image. Use the fine focus adjustment knob to refocus the image.
Detailed explanation-2: -The condenser aperture diaphragm is responsible for controlling the angle of the illuminating light cone and, consequently, the numerical aperture of the condenser.
Detailed explanation-3: -Condenser Diaphragm-This diaphragm controls the amount of light entering the lens system. This feature is useful for viewing unstained biological specimens that are translucent. Reducing the amount of light improves contrast, making the specimen “stand out” against the background.
Detailed explanation-4: -Under what conditions would you adjust the diaphragm? Used to vary the intensity and size of cone of light that hits the slide.
Detailed explanation-5: -Condenser and Field Diaphragm Alignment Correct adjustment of the condenser aperture diaphragm is one of the most critical aspects for obtaining superior image quality, because it controls the numerical aperture, resolving power, depth of field, and the overall image character.
