Let's identify each labeled part of the microscope in the image and provide their correct names. Here is a breakdown of each lettered part:
---
A. Eyepiece (Ocular Lens)
- This is the lens at the top of the microscope that you look into. It magnifies the image produced by the objective lenses.
B. Body Tube
- The tube that connects the eyepiece to the nosepiece. It holds the optical components in alignment.
C. Coarse Adjustment Knob
- The larger knob used to raise or lower the stage quickly for initial focusing.
D. Fine Adjustment Knob
- The smaller knob used to make small, precise adjustments to focus after using the coarse knob.
E. Objective Lenses (Nosepiece)
- The rotating turret with multiple lenses (usually 4x, 10x, 40x, 100x) that magnify the specimen. The nosepiece holds these lenses.
F. Arm
- The curved part that supports the upper portion of the microscope and is used to carry the microscope.
G. Stage
- The flat platform where the slide is placed for viewing. It often has clips to hold the slide in place.
H. Diaphragm (Iris Diaphragm)
- Located beneath the stage, it controls the amount of light passing through the specimen.
I. Condenser
- A lens system located below the stage that focuses light onto the specimen. It helps improve illumination and contrast.
J. Base
- The bottom part of the microscope that supports the entire structure and houses the light source.
