Study Notes
Troubleshooting Microscope Issues
- Encountering problems like unclear images, dim lighting, or non-functional bulbs is common in microscope use.
- Always consult standard operating procedures (SOPs) and the microscope's user manual to guide troubleshooting.
- Seeking assistance from a supervisor is advisable when issues arise.
Black Field in the Oculars
- A completely black view through the oculars may indicate:
- Microscope is not plugged in.
- Power outlet is not supplying electricity.
- Objective lens is not properly secured in place.
- Bulb may be burned out or improperly installed.
- Condenser is positioned too low with the diaphragm fully closed.
Blurred Image
- A blurred image in the oculars can be due to:
- Objective lens is dirty.
- Presence of oil contamination in the objective.
- Coverslip or microscope slide is dirty.
- Slide might be placed upside down.
Problem Focusing
- Difficulty focusing while using the microscope could stem from:
- Slide not correctly positioned on the stage.
- Misalignment of the microscope.
- Parfocal adjustments required.
- Focus mechanism may be jammed.
- Presence of oil on the stage.
Light Flickers
- Flickering or surging light when switched on can be from:
- Damaged wiring in the power cord.
- Bulb nearing the end of its life.
- Bulb not correctly inserted into the socket.
Partial Illumination
- Observing partial illumination in the field can be caused by:
- Objective not adequately clicked into position.
- Incorrect centering of the condenser.
- Lower than appropriate condenser height.
- Insufficient opening of the field diaphragm.
