MICROANATOMY

Detailed explanation-1: -Coarse Adjustment Knob-The coarse adjustment knob located on the arm of the microscope moves the stage up and down to bring the specimen into focus. The gearing mechanism of the adjustment produces a large vertical movement of the stage with only a partial revolution of the knob.

Detailed explanation-2: -turn the coarse adjustment knob to raise the stage until the low-power objective almost touches the slide. turn the coarse objective knob until the specimen comes into focus. CAUTION: If you turn too quickly the slide could hit and break the objective lens.

Detailed explanation-3: -7. Focusing knobs: located on both sides of the microscope. The larger, inner coarse adjustment knob moves the stage up and down much faster and farther than the smaller, outer fine adjustment knob. The coarse adjustment knob is used ONLY with the low power (4X, 10X) objectives.

Detailed explanation-4: -Focusing the Microscope: This objective is the easiest to focus and center the image in the field of view. While looking at the objective lens and the stage from the side, turn the coarse focus knob so that the stage moves upward toward the objectives. Move it as far as it will go without touching the slide.
