What the bottom part of the microscope?

Answer 1

1. Ocular Lens (Eyepiece) - where you look through to see the image of your specimen. Magnifies the specimen 10X actual size.

2. Body tube - the long tube that supports the eyepiece and connects it to the objectives.

3. Nosepiece - the rotating part of the microscope at the bottom of the body tube; it holds the objectives.

4. Objective Lenses - (low, medium, high). Depending on the microscope, you may have 2, 3 or more objectives attached to the nosepiece; they vary in length (the shortest is the lowest power

or magnification; the longest is the highest power or magnification).

5. Arm - part of the microscope that you carry the microscope with; connects the head and base of the microscope.

6. Coarse Adjustment Knob - large, round knob on the side of the microscope used for "rough" focusing of the specimen; it may

move either the stage or the upper part of the microscope. Location may vary depending on microscope - it may be on the

bottom of the arm or on the top.

7. Fine Adjustment Knob - small, round knob on the side of the microscope used to fine-tune the focus of your specimen after

using the coarse adjustment knob. As with the Coarse Adjustment Knob, location may vary depending on the microscope.

8. Stage - large, flat area under the objectives; it has a hole in it (see aperture) that allows light through; the specimen/slide is

placed on the stage for viewing.

9. Stage Clips - clips on top of the stage which hold the slide in place.

10. Aperture - the hole in the stage that concentrates light through the specimen for better viewing.

11. Diaphragm - controls the amount of light going through the aperture; may be adjusted.

12. Light or Mirror - source of light usually found near the base of the microscope; used to direct light upward through the

microscope. The light source makes the specimen easier to see.

Answer 2

The bottom part of a microscope typically consists of the base, which provides stability and support for the entire microscope. It may also house the light source such as a built-in electric light or a mirror for reflecting natural light. Additionally, some microscopes have built-in mechanical stage controls for moving the specimen.
