What Is Microscopy?

Microscopy is the science of magnifying objects that are too small to be seen with the naked eye. It's at the heart of scientific discovery, manufacturing control, and forensic investigation. From nanotechnology to semiconductor inspection, microscopy allows us to explore and manipulate materials at a microscopic level.

How to Choose the Right Microscope

The Right Microscope Starts with the Right Questions

Choosing the ideal microscope for your work doesn’t have to be complicated  but with so many models, optics, and features available, it’s easy to feel overwhelmed. At Optotek, we simplify the decision-making process by helping you focus on what really matters for your application, budget, and workflow.

Here are the 5 key factors to consider when selecting the microscope that best suits your needs:

1.  Application: What will you be using the microscope for?

Are you:

  • Inspecting microelectronics for quality control?
  • Conducting biological or clinical research?
  • Assembling precision components in manufacturing?
  • Teaching students or performing routine lab analysis?

Your field determines whether you’ll need a stereo microscope, a compound microscope, or a digital inspection system.

2.  Lighting: How is your sample illuminated?

Lighting is more than a detail  it's essential.

  • Transmitted light (from below) is ideal for transparent samples like biological slides.
  • Reflected light (from above) is used for opaque objects like metal surfaces or PCBs.
  • Dual illumination systems allow you to toggle between both.

Tip: Choose adjustable LED or halogen lighting for greater contrast control and precision.

3. Imaging: Do you need a camera or screen output?

  • Want to capture, document, or share images? You'll need a system with a digital camera, USB or HDMI output.
  • Working with teams or students? A live display screen can speed up collaboration.
  • Need measurement tools or annotation? Choose a model with integrated imaging software.

At Optotek, we offer plug-and-play digital systems with up to 4K resolution.

4.  Magnification Range: How small is the detail you need to see?

Magnification should match your specimen size and the level of detail required.

  • For biological cells, you may need 400x to 1000x magnification.
  • For circuit boards or mechanical parts, a 10x to 80x stereo range is typically sufficient.
  • Metallurgical analysis may require higher power with reflected light.

We’ll help you strike the right balance between magnification and working distance.

5.  Accessories: Do you need specialized tools or add-ons?

  • Micrometer slides for calibration
  • Polarizers or filters for contrast enhancement
  • Measurement software for dimensional analysis
  • Mechanical stages for precise movement

Our microscopes are modular and upgradeable, so you can add what you need  when you need it.

Compound Microscopes


Are essential tools for viewing small, thin specimens at high magnifications, typically ranging from 40x to 1000x. They use multiple lenses to achieve detailed, clear images of biological samples such as cells, tissues, and microorganisms. Ideal for laboratories, educational settings, and clinical diagnostics, compound microscopes offer transmitted light illumination, allowing light to pass through transparent specimens for optimal visualization. Their precision and versatility make them indispensable in research and medical analysis.


 Stereo Microscopes

Also known as dissecting microscopes, provide a three-dimensional view of larger, solid specimens at lower magnifications, usually between 10x and 80x. Unlike compound microscopes, they use two separate optical paths to create depth perception, making them perfect for inspecting circuit boards, small mechanical parts, insects, or plant materials. Equipped with reflected light from above, stereo microscopes are widely used in industrial inspection, quality control, and educational labs where seeing the surface detail and spatial relationships is crucial.

Microscope objectives

Are the most critical lenses in a microscope, responsible for gathering light from the specimen and magnifying its image. They come in various magnification powers commonly 4x, 10x, 40x, and 100x and different designs such as achromatic, plan, and apochromatic, which correct optical distortions and improve image clarity. High-quality objectives ensure sharp, bright, and color-accurate images, essential for detailed analysis in biological, medical, and industrial applications. Selecting the right objective lenses tailored to your microscopy needs is key to achieving optimal resolution and contrast.
