2. Microscope Components
Familiarize yourself with the main parts of your microscope:
- Eyepiece: Where you look to view the specimen. Interchangeable (WF10x, WF25x).
- Monocular Head: Rotates 360 degrees for flexible viewing.
- Objective Lenses: Multiple lenses (4x, 10x, 40x) mounted on a revolving nosepiece to change magnification.
- Stage: Flat platform where slides are placed for observation. Equipped with slide clips.
- Coarse Focus Knob: Large knob for initial, rapid focusing.
- Fine Focus Knob: Smaller knob for precise, sharp focusing.
- Illuminator (Bottom): Transmitted LED light source for translucent specimens.
- Illuminator (Top): Incident LED light source for opaque specimens.
- Brightness Adjustment Knob: Controls the intensity of the LED illumination.
- Power Switch: Turns the microscope's illumination on/off.
- Filter Wheel: Rotatable disc with colored filters beneath the stage.
- Phone Adapter: Attachment for securing a smartphone to the eyepiece for digital viewing and capture.
3. Setup Instructions

4. Operating the Microscope
- Turn on Illumination: Flip the power switch to turn on the LED lights. Adjust the brightness using the dimmer knob. Choose between top, bottom, or dual illumination based on your specimen type.
Figure 5: This image illustrates the dual LED illumination system, showing how light can be directed from above (incident) or below (transmitted) the specimen, or both, with adjustable brightness. - Select Objective Lens: Rotate the revolving nosepiece to select the lowest magnification objective lens (4x) first. This provides the widest field of view for initial specimen location.
- Focusing:
- Use the coarse focus knob to bring the specimen into approximate focus.
- Use the fine focus knob for sharp and detailed focusing.
- Adjust Magnification: Once the specimen is in focus at low power, rotate the nosepiece to a higher magnification objective (10x, 40x). Re-adjust focus using the fine focus knob.

This can enhance contrast and visibility for transparent specimens.
- Smartphone Integration: Attach the phone adapter to the eyepiece. Secure your smartphone in the adapter. Open your phone's camera app and align it with the eyepiece to view, capture photos, or record videos of the magnified image.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No illumination | Power not connected; batteries drained; power switch off. | Check power adapter connection; replace batteries; turn on power switch. |
| Image blurry | Incorrect focus; dirty lens/slide; wrong objective lens. | Adjust coarse/fine focus; clean lenses/slide; select appropriate objective. |
| Dark field of view | Insufficient illumination; diaphragm closed; wrong filter. | Increase brightness; open diaphragm; change filter. |
