Microscopes play a vital role for accuracy across a variety of speciality fields like dentistry, otolaryngology, ophthalmology, and gynaecology.
However, even small mistakes such as scratching an objective, wiping with inappropriate materials, or failing to calibrate can quickly compromise image clarity, impair equipment performance, and reduce its lifespan.
In a nutshell, microscopes only work best when handled carefully, and overlooking these basic guidelines often leads to blurred images and long‑term damage to fragile parts.
By following our guide of microscope best practices, you can preserve image quality and extend the longevity of your investment.
How Should a Microscope be Carried?
Incorrect Carrying and Support
Proper carrying is especially important in clinical environments where microscopes are moved frequently between rooms or stations.
Never carry your microscope just by its eyepiece, stage, or arm alone. By miscarrying your microscope like that, you risk breaking the instrument, damaging internal parts, or misaligning the optics.
The correct way to carry your microscope is with both hands, one to support the base and the other to firmly hold the arm. Always hold the microscope upright as tilting it could cause lenses to come loose or spill immersion oil.
Forcing Coarse or Fine Focus Knobs
In specialist fields where microscopic accuracy is extremely important, forcing the focus can ruin both the observation and the microscope itself.
Microscope focusing knobs are designed for precision, not force. If you apply more pressure when the stage resists movement, it can strip gears, damage the rack-and-pinion system, and reduce accuracy.
At low power, always start with the coarse focus and adjust your microscope with the fine focus at greater magnifications. If the knobs feel stiff, stop immediately; because this is a mechanical problem that should be fixed with lubrication or cleaning, not more force.
The Do’s and Don’ts When Cleaning a Microscope
Maintaining image quality as best as possible and extending your microscope lifespan are greatly affected on proper cleaning practises. We have listed some guidelines to follow, and mistakes to avoid:
Do’s: Microscope Cleaning Best Cleaning Practices
- Wipe external surfaces daily with a soft, lint-free cloth to remove dust and fingerprints.
- Inspect lenses and the stage regularly for dust, oil or particles that might impair image clarity.
- Clean lenses gently using lens paper or a microfibre cloth.
- When wiping, go in straight lines from the centre outward.
- Use appropriate cleaning tools and solutions: compressed air for dislodging dust, and alcohol-free formulas suitable for coated optics.
- Lubricate moving parts periodically, such as focus knobs and the mechanical stage, with manufacturer-approved lubricants.
Don’ts: Common Microscope Cleaning Mistakes to Avoid
- Do not use household cleaners, tissues or rough cloths, because they can scratch optics or leave behind damaging residues.
- Never touch lenses with your fingers, as your skin’s natural oils can smudge your microscope lens which will impair clarity over time.
- When wiping, avoid circular motions.
- Avoid applying cleaning solutions directly onto optical surfaces.
- Do not use harsh solvents like acetone, as they can damage plastic parts or coatings.
- Do not disassemble complex optical components, such as objectives or condensers as these should be handled only by trained professionals.

Ineffective Microscope Observation Techniques
Even high-quality Zumax microscopes can give poor results if observation techniques are incorrect.
Light levels that are too high or too low might blur details and lessen contrast. Always adjust light intensity and angle for each sample.
Inverted and compound microscopes need regular calibration for accurate measurements and aligned optics. Skipping this step can compromise experimental results and image precision.
Accurate results also depend on correct microscope declination angles, which influence both visual precision and user comfort.
Summary: Use Your Microscope the Right Way
Handle, observe, and maintain your microscope correctly to preserve optical clarity, prevent damage, and extend its lifespan. Proper carrying, lighting, calibration, cleaning, and stage lubrication results in accurate and reliable results with Zumax microscopes.
