This is a
Microscope Parts Worksheet designed to help students identify and label the various components of a compound light microscope. Below is the
completed labeling of each part, based on standard biological microscopy knowledge.

🔬 Labeling the Microscope Parts
Here’s how each labeled line corresponds to the correct part:
####
✔ Left Side (From Top to Bottom):
1.
Eyepiece (Ocular Lens) – The lens you look through at the top of the microscope.
2.
Binocular Head – The part that holds the eyepieces; allows viewing with both eyes.
3.
Revolver (Nosepiece) – The rotating turret that holds the objective lenses.
4.
Objective Lenses – The set of lenses (usually 4x, 10x, 40x, 100x) that magnify the specimen.
5.
Stage Clips – Small clips that hold the slide in place on the stage.
6.
Stage – The platform where the slide is placed for viewing.
7.
Diaphragm (Iris Diaphragm) – Controls the amount of light passing through the specimen.
8.
Condenser – Focuses light onto the specimen.
9.
Coarse Adjustment Knob – Large knob used to move the stage up/down quickly for initial focusing.
10.
Fine Adjustment Knob – Smaller knob for precise focusing after coarse adjustment.
####
✔ Right Side (From Top to Bottom):
1.
Arm – The curved support that connects the head to the base; used to carry the microscope.
2.
Base – The bottom part that supports the entire microscope and houses the light source.
3.
Light Source (Illuminator) – The built-in light at the base that shines up through the specimen.
4.
On/Off Switch – Turns the light source on or off.
5.
Power Cord / Battery Compartment – For powering the light source (if not battery-powered).
> ⚠️ Note: Some labels may vary slightly depending on the microscope model, but these are standard terms used in A-Level Biology.

💡 Explanation of Key Functions:
-
Eyepiece & Objective Lenses: Together provide total magnification (e.g., 10x eyepiece × 40x objective = 400x).
-
Stage & Stage Clips: Hold the slide securely.
-
Adjustment Knobs: Help focus the image — coarse for big adjustments, fine for precision.
-
Condenser & Diaphragm: Control illumination and contrast.
-
Arm & Base: Structural support and portability.
