Explanation:
Detailed explanation-1: -COARSE ADJUSTMENT KNOB-A rapid control which allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing. 5. FINE ADJUSTMENT KNOB-A slow but precise control used to fine focus the image when viewing at the higher magnifications.
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).
