Detailed explanation-1: -IRIS DIAPHRAGM CONTROL-A lever (or rotating disk) that adjusts the amount of light illuminating the slide. Use just enough light to illuminate the object on the slide and give good contrast. 15. FILTER HOLDER-A blue filter rests in this holder below the substage condenser.
Detailed explanation-2: -When the iris diaphragm has opened, the amount of light passing through increases, and therefore the specimen is more illuminated, and the resolution will increase. The image is made brighter and therefore more apparent, but the downside is that the clarity is decreased.
Detailed explanation-3: -The condenser aperture diaphragm is responsible for controlling the angle of the illuminating light cone and, consequently, the numerical aperture of the condenser.
