What are different types of optical microscopes?
microscopes are tools that allow the user to see things on a larger scale by creating a precise enlarged image of small objects. Microscopes are classified in the way the image is enlarged. Mikroscopy types include acoustic microscopes, electron microscopes, X-ray microscopes and optical microscopes-called light microscope-Subject here. Optical microscopes use glass lenses to produce enlarged images. They come in several different configurations: simple optical microscopes use only one lens, while optical microscopes combine two or more fields of lenses. It consists of a single or folded lens. Examples of simple lenses are magnifying glass, jewel lens or loot and reading glass. Several types of aberration in one lens are possible. Each of these affects the image quality in a different way. Chromatic aberrations distort color. The spherical aberration disrupts the periphery of the image peripheral. The distortion produces a curve where the image is straight.
SimpleThe microscope of the folded lens varies from a folded microscope. The folded lens is a field of simple lenses that share a common axis. The compound lens determines some aberrations that may occur when only one lens is used, and can also increase at higher strength.
Thefolded microscope has at least two lenses fields, allowing greater magnification than a simple microscope is capable. One of these fields is the goal. It is located near the tested object and has a short focal length. The eyepiece, also known as eye, raises a real image created by the goal and creates a virtual image.
The basic form of an optical microscope of the compound is monocular. Two types are made for two eyes. In one case, the only object is used with a pair of eyepulators and creates a two -dimensional view that can be seen through both eyes and is therefore binocular. However, a stereoscopic microscope has not only two eyepieces but also two targets, so the ObjeEKT appears three -dimensional.
merged optical microscopes were invented by three Dutch goggles at the end of the sixteenth century. It was this type of microscope, which was used about 70 years later Robert Hooke in his demonstrations for royal society. It was about ten years after Hooke launched his demonstration that Antonie van Leeuwenhoek began to use hand -made simple optical microscopes to observe freshwater microorganisms and the field of microbiology had its beginnings.
