The task is to label the parts of a compound light microscope. Below is the solution with explanations for each part:
Microscope Parts Worksheet
####
Left Side Labels (Top to Bottom)
1.
Eyepiece (Ocular Lens)
- The lens at the top through which you look to view the specimen.
2.
Head Arm/Body Tube
- Connects the eyepiece to the objective lenses, allowing light and magnified images to pass through.
3.
Objective Lenses
- The lenses closest to the specimen that provide the primary magnification.
4.
Nosepiece (Turret)
- The rotating part that holds the objective lenses and allows you to switch between different magnifications.
5.
Stage Clips
- Hold the microscope slide in place on the stage.
6.
Stage
- The flat platform where the microscope slide is placed.
7.
Coarse Adjustment Knob
- Used for large adjustments in focus to bring the specimen into general focus.
8.
Fine Adjustment Knob
- Used for small, precise adjustments in focus to sharpen the image.
9.
Base
- The bottom part of the microscope that provides stability and support.
####
Right Side Labels (Top to Bottom)
10.
Arm
- The curved part that connects the head arm to the base, providing a handle for carrying the microscope.
11.
Illuminator/Light Source
- Provides light that passes through the specimen for viewing.
12.
Diaphragm/Iris Diaphragm
- Controls the amount of light passing through the specimen, affecting contrast and brightness.
13.
Condenser
- Focuses light onto the specimen for better illumination.
14.
Aperture Lever
- Adjusts the size of the aperture in the condenser to control the intensity and distribution of light.
15.
Mirror
- Reflects external light into the illuminator (not visible in modern microscopes with built-in light sources).
16.
Power Switch
- Turns the microscope's light source on or off.
