The main difference between microscoping and magnifying
Microscope is also an aid to the eye, it is mainly used to observe the minute details of close objects, its widely used in various scientific and technical fields, is an extremely important visual optical instruments.
Working Principle of Microscope
Microscope and magnifying glass play the same role, that is, will be close to the tiny objects into a magnified image, the image of the human eye angle is much larger than the human eye directly look at the object when the angle of view.
The difference between the two is that the magnifying glass magnification is not high, generally below 15X; while the visual magnification of the microscope can reach more than 1000 times.
Magnifying glass composition structure is relatively simple, generally just a set of lenses, the essence of the primary magnification; and microscope composition structure is more complex, generally two sets of lenses, the essence of the secondary magnification.
The principle of secondary magnification of the microscope is the first use of a shorter focal length of the lens will be a tiny object into a magnified real image, that is, the object is laterally enlarged a number of times, and then use an enlarged "magnifying glass" to observe this has been horizontally enlarged once like.
