The basics of using a microscope

A microscope is an optical instrument that allows us to observe objects too small to be seen with the naked eye by magnifying them using lenses. Thanks to increasingly powerful illumination systems and objectives, it is possible to examine cells, tissues, microorganisms, and even materials with remarkable precision.

The principle is based on:

• A system of lenses (objective and eyepiece) that enlarges the image.
• A light source (LED or halogen) that illuminates the sample.
• A stage where the sample to be observed is placed.
• Micrometric adjustments to achieve a sharp and precise image.

Modern microscopes also sometimes incorporate advanced technologies such as phase contrast, fluorescence or polarization to further improve the observation of certain specific cellular structures.

Why choose an optical microscope?

The optical microscope is the ideal solution for most common needs: education, biology, medicine, scientific research, and even the pharmaceutical industry. It uses visible light to form a magnified image and remains accessible, easy to use, and economical compared to electron microscopes.

Thanks to interchangeable objectives (4x, 10x, 40x, 100x), it covers a wide range of magnifications, suitable for numerous applications: observation of bacteria, animal and plant cells, tissues, crystals, etc.

Frequently Asked Questions About Microscopes

What are the most commonly used types of microscopes?

The most common types of microscope are:

• The optical microscope : it uses visible light and lenses to magnify samples.
• Scanning electron microscope (SEM) : This uses an electron beam to provide much higher magnification and resolution.
• The digital microscope : it captures images via a camera and displays them on a live screen.

For classical biology or teaching applications, the optical microscope remains the number one choice thanks to its ease/price ratio.

What is the difference between a light microscope and an electron microscope?

The main difference lies in the type of radiation used:

• The optical microscope uses visible light to observe samples. It is ideal for living cells, biological tissues, plants, and transparent materials.
• The electron microscope uses an electron beam, which allows for extreme magnifications, up to several hundred thousand times. It is used to study ultra-fine structures such as viruses, proteins, or nanotechnological materials.

In terms of price, optical microscopes are much more affordable than electronic models.

How to maintain a microscope to extend its lifespan?

Proper maintenance of your microscope is essential to ensure quality observations for many years:

• Clean lenses regularly with special non-abrasive papers and a suitable solution.
• Always protect the microscope under a cover when not in use to prevent dust accumulation.
• Always handle the device carefully, holding the base and the microscope arm to avoid shocks.
• Avoid prolonged exposure to humid or dusty environments.
• Have professional maintenance carried out every 2 to 3 years if you use your equipment intensively.

At Rewake, our refurbished models are delivered cleaned, adjusted and calibrated for immediate use without any unpleasant surprises.

How to choose the right microscope for your project?

For school or amateur use:

A monocular optical microscope with 40x to 400x magnification is ideal for exploring cells, insects, or plants. It's an affordable investment, perfect for learning the basics of microscopy.

For a university or medical laboratory:

Choose a high-precision binocular microscope with plan-achromatic objectives, adjustable LED illumination and possibly the ability to add a digital camera for on-screen image analysis.

For advanced search:

Fluorescence, phase contrast, or polarization microscopes should be considered, depending on the specimens being studied. Some projects may also require an electron microscope, which is much more expensive but essential for nanoscale structures.

Some common mistakes to avoid when buying a microscope

When choosing your microscope, avoid these common mistakes:

• Relying solely on maximum magnification is not the only important criterion. Optical quality is paramount.
• Forgetting to check compatibility with accessories (cameras, additional lenses, etc.).
• Neglecting the quality of lighting: Poor lighting will make your observations difficult, even with good lenses.
• Choose a low-end microscope for intensive professional use: it will wear out quickly and become unreliable.
