May 30, 2024 · Learn about the microscope, an instrument that produces enlarged images of small objects, from optical, electron, acoustic, X-ray, and other types. Explore the history, parts, diagram, and facts of microscopy and its applications in science and medicine.
- The word “microscope” comes from the Latin “microscopium,” which is derived from the Greek words “mikros,” meaning “small,” and “skopein,” meaning...
- It is not definitively known who invented the microscope. However, the earliest microscopes seem to have been made by Dutch opticians Hans Janssen...
- Microscope slides are small rectangles of transparent glass or plastic, on which a specimen can rest so it can be examined under a microscope.
The microscope can detect, resolve and image the smallest items of evidence, often without any alteration or destruction. The microscope is used to identify and compare fibers, hairs, soils, and dust...etc. In ink markings, blood stains or bullets, no specimen treatment is required and the evidence shows directly from microscopical ...
Oct 19, 2023 · Learn about the history, types, and uses of microscopes, instruments that magnify small objects and cells. Find out how lenses, magnification, and light work in different microscopes.
May 10, 2022 · Learn how microscopes use lenses to magnify tiny objects and reveal the invisible world of atoms and cells. Find out how different types of microscopes, such as optical and electron microscopes, work and why we need them.
- Light Microscopes. The most common type of microscope you’re likely to come across, these microscopes rely on lenses and light to illuminate a specimen for optimal image-gathering.
- Compound Microscopes. You’ve undoubtedly peered into this type of microscope in your lifetime. Compound microscopes can be found in schools and labs across the world.
- Stereoscopic Microscopes. These are common in labs and educational settings, as well. A stereoscopic microscope has a light source on the top to illuminate the specimen, causing reflection into the microscope lens.
- Confocal Microscopes. Confocal microscopes use lasers to scan a specimen and create high resolution, high magnification images. Because they provide depth-selection by scanning the specimen, they can create sectional detail (without physical dissection) that can be used to build a 3D image.
A microscope is an instrument that magnifies objects otherwise too small to be seen, producing an image in which the object appears larger. Most photographs of cells are taken using a microscope, and these pictures can also be called micrographs.
With a microscope, a relay lens system replaces the single lens; an objective and an eyepiece work in tandem to project the image of the object onto the eye, or a sensor – depending upon the application. There are two parts to a microscope that increase the overall system magnification: the objective and the eyepiece.
