What is the first step in focusing the microscope?

Focusing the Microscope:

1. Start by turning the revolving nosepiece (turret) so that the lowest power objective lens is “clicked” into position.
2. 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.

What is the correct way to focus a microscope?

1. Start by rotating the objective lens to lowest power.
2. Place a slide on the stage, label side up, with the coverslip centered.
3. On LOW POWER ONLY, use the coarse focus knob to get the object into focus.
4. If you cannot see anything, move the slide slightly while viewing and focusing.

What happens to a microscope if placed at the edge?

When the object on your slide is in focus for each objective, the distance between the slide and the objective lens, the working distance, decreases as the objective magnification increases. Like the human eye, the lenses of your microscope provide a limited depth of focus. Switch to a higher power objective.
