MICROANATOMY

Detailed explanation-1: -Coarse adjustment knob-Focuses the image under low power (usually the bigger knob) Fine adjustment knob-Sharpens the image under all powers (usually the smaller knob) Arm-supports the body tube and is used to carry the microscope.

Detailed explanation-2: -The microscope’s fine adjustment knob makes fine adjustments to the focus. We first use the coarse adjustment knob to perform significant stage position adjustments before focusing on an object. The object is then brought into focus by turning the fine adjustment knob as we move the stage closer to the target.

Detailed explanation-3: -The coarse focus knob makes large adjustments, while the fine focus knob makes smaller adjustments. At a high power objective, the focus will change rapidly as the objective lens is adjusted, so only the fine focus knob should be used in order to prevent overshooting the correct focal plane.

Detailed explanation-4: -The fine-adjustment knob on a light microscope focuses by moving the lens slowly and is used to focus on the specimen more clearly. It is used with the high-power objective lenses. The course-adjustment knob focuses by moving the lens quickly and is used to find the specimen your are observing.
