Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).

The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
It is a contrast imaging technology using the difference in absorption of soft X-rays in the water window region (wavelengths: 2.34–4.4 nm, energies: 280–530 eV) by the carbon atom (main element composing the living cell) and the oxygen atom (an element of water). Microfocus X-ray also achieves high magnification by projection. A microfocus ...
The stereo microscope should not be confused with a compound microscope equipped with double eyepieces and a binoviewer. In such microscopes, both eyes see the same image, with the two eyepieces serving to provide greater viewing comfort. However, the image in those microscopes is no different from that obtained with a single monocular eyepiece.
An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties. Common examples include periscopes, microscopes, telescopes, and cameras. [1] [2]
(a) Optically sectioned fluorescence images of a pollen grain. (b) Combined image. (c) Combined image of a group of pollen grains. [1]Optical sectioning is the process by which a suitably designed microscope can produce clear images of focal planes deep within a thick sample.
The viewer sees the images from both microscopes next to one another, as in the inset image. A comparison microscope is a device used to analyze side-by-side specimens. It consists of two microscopes connected by an optical bridge, which results in a split view window enabling two separate objects to be viewed simultaneously. This avoids the ...
