A microscope (from the Ancient Greek: μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small to be seen by the naked eye.
There are many types of microscopes, and they may be grouped in different ways. One way is to describe the way the instruments interact with a sample to create images, either by sending a beam of light or electrons to a sample in its optical path, or by scanning across, and a short distance from the surface of a sample using a probe.
When viewed under a microscope, certain things reveal fascinating details that are not visible to the naked eye. Here are six examples of things that look significantly different under a microscope:
Insects: Examining insects under a microscope showcases intricate details of their exoskeleton, compound eyes, delicate wings, and tiny hairs that aid in their sensory functions. It reveals a whole new level of complexity and beauty.
Plants and Leaves: Microscopic examination of plants and leaves unveils intricate cellular structures, such as stomata (pores for gas exchange), leaf veins, and trichomes (hairs). These structures play crucial roles in photosynthesis, transpiration, and protection.
Human Skin: When viewed under a microscope, human skin displays a complex network of pores, hair follicles, sweat glands, and the outermost layer known as the epidermis. It highlights the texture and structure that contribute to its functions as a protective barrier.
Crystals: Microscopy allows us to see the crystal structures of various substances. It reveals the symmetrical patterns and geometric arrangements of atoms that form crystals, giving insight into their unique properties and characteristics.
Blood Cells: The examination of blood cells under a microscope provides a closer look at red blood cells (erythrocytes) responsible for oxygen transport, white blood cells (leukocytes) involved in the immune response, and platelets (thrombocytes) essential for blood clotting.
Textiles and Fabrics: Under a microscope, textiles and fabrics show intricate weaves and fibers. It allows us to observe the different types of threads, patterns, and textures, helping in understanding the quality and characteristics of the material.
Exploring these and many other objects under a microscope unveils a hidden world of remarkable details, providing valuable insights into their structures and functions.
The most common microscope (and the first to be invented) is the optical microscope, which uses light to pass through a sample to produce an image. Other major types of microscopes are the fluorescence microscope, the electron microscope (both the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscopes.
