The world we see with our eyes is only the tip of the iceberg. However, beneath the surface, a wealth of intricate details and captivating secrets await discovery. Microscopes are versatile tools that provide insights into the unseen world. To unleash the magic of the hidden world, a Dutch father-son team named Hans and Zacharias Janssen invented the first so-called compound microscope in the late 16th century. And then in 1609, Galileo Galilei developed the first compound microscope with a convex and concave lens. Today, microscopy technology enabled to view matter smaller than 0.2 micrometers. In this article, we will talk about types and applications of microscopes.
Types of Microscopes
There are the 3 main types of microscopes: optical microscopes, electron microscopes and scanning probe microscopes.
- Compound Microscopes
Compound Microscopes are the most common types of microscopes. And they are the most often used microscopes in laboratories and educational settings. Generally speaking, a compound microscope is used for viewing samples at high magnification(40-1000x).
- Stereo Microscopes
Stereo microscopes, also known as stereoscopic or dissecting microscopes, are Ideal for viewing larger specimens. These microscopes are intended for three-dimensional (3D) viewing of objects at relatively low magnifications.
- Transmission Electron Microscopes (TEM)
A transmission Electron Microscope is a powerful type of electron microscope that uses a beam of electrons to illuminate a thin specimen, allowing scientists to investigate structures at the atomic level. TEM has become an invaluable tool in various scientific fields, including biology, materials science, and nanotechnology.
- Scanning Electron Microscopes (SEM)
SEMs use a focused beam of electrons that scans the surface of a specimen. The electron beam interacts with the specimen, and the emitted or backscattered electrons are detected to create detailed surface images.
Scanning Probe Microscopes
- Atomic Force Microscopes (AFM)
AFM measures forces between a sharp tip and the specimen surface.
2.Scanning Tunneling Microscopes (STM)
STM measures the current flowing between a sharp tip and the specimen surface.
Applications of Microscopes
Microscopes have a wide range of applications across various scientific disciplines. Here are some key applications. In medicine, microscopes provide a close-up view of tissues and cells, aiding in the diagnosis of diseases. In biology, microscopes reveal the intricacies of cell structure and genetic material. Materials scientists utilize microscopes to study the microstructure of metals, polymers, and nanomaterials, leading to advancements in materials science. Environmental scientists employ them to study microorganisms and pollutants, contributing to our understanding of ecological systems. Microscopes are essential tools for students in education, allowing them to explore the microscopic world. Industry relies on microscopes for quality control, inspecting electronic components and ensuring product integrity. Whether you’re into biology, geology, or simply curious about the hidden wonders of nature, the APEXEL MS003 is your perfect companion. One standout feature is the inclusion of a specimen stage with adjustable LED lighting.
