The image shows a compound light microscope with labeled parts numbered from 1 to 14. Below is the identification and explanation of each labeled part:
---
1. Eyepiece (Ocular Lens)
- This is the lens at the top of the microscope that you look through. It typically magnifies the image 10x. The total magnification is calculated by multiplying the eyepiece magnification by the objective lens magnification.
2. Revolving Nosepiece (Turret)
- This is the rotating part that holds the objective lenses. You can switch between different objective lenses (e.g., 4x, 10x, 40x) by rotating this turret.
3. Objective Lenses
- These are the lenses located beneath the nosepiece. They provide different levels of magnification (e.g., 4x, 10x, 40x). The total magnification is determined by multiplying the objective lens magnification by the eyepiece magnification.
4. Stage Clips
- These are small metal clips on the stage that hold the slide in place while viewing.
5. Stage
- This is the flat platform where the slide is placed for viewing. It often has an opening for light to pass through the specimen.
6. Diaphragm (Iris Diaphragm)
- Located beneath the stage, it controls the amount of light that passes through the specimen. Adjusting it can improve contrast and clarity.
7. Condenser
- Positioned below the stage, it focuses the light onto the specimen. It helps to illuminate the sample evenly.
8. Light Source (Illuminator)
- Located at the base of the microscope, it provides the light needed to view the specimen. In modern microscopes, this is often an LED or bulb.
9. Arm
- The curved support that connects the head (eyepiece) to the base. It's used to carry the microscope when moving it.
10. Head (Body Tube)
- This is the upper part of the microscope that connects the eyepiece to the objective lenses. It maintains the proper distance between the lenses.
11. Coarse Adjustment Knob
- This knob moves the stage up and down rapidly to bring the specimen into rough focus. Used primarily when using lower power objectives.
12. Fine Adjustment Knob
- This knob makes small adjustments to the focus, allowing for precise focusing, especially at higher magnifications.
13. Base
- The bottom part of the microscope that supports the entire structure and houses the light source.
14. Foot (Base Support)
- The wide, stable bottom that keeps the microscope balanced and prevents tipping.

Summary of Key Functions:
-
Magnification: Achieved by combining the eyepiece (1) and objective lenses (3).
-
Focus: Controlled by coarse (11) and fine adjustment knobs (12).
-
Light Control: Managed by the diaphragm (6) and condenser (7), with illumination from the light source (8).
This microscope is a typical compound light microscope used in biology labs for viewing small specimens like cells.
