GENERAL HISTOLOGY

Detailed explanation-1: -Fine Adjustment Knob-This knob is inside the coarse adjustment knob and is used to bring the specimen into sharp focus under low power and is used for all focusing when using high power lenses.

Detailed explanation-2: -Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above). Microscopes with in-stage condenser lenses render a sharper image than those with no lens (at 400x).

Detailed explanation-3: -Focus (coarse), The coarse focus knob is used to bring the specimen into approximate or near focus. Focus (fine), Use the fine focus knob to sharpen the focus quality of the image after it has been brought into focus with the coarse focus knob.

Detailed explanation-4: -FINE ADJUSTMENT KNOB-A slow but precise control used to fine focus the image when viewing at the higher magnifications. 6. BASE-The part of your microscope that sits on a level, stable support. 7.
