The difference between a microscope and a telescope

Telescope

1. What is a microscope?  

The microscope is a technology used to observe the structure of tiny objects that cannot be distinguished by the naked eye. It is widely used in scientific research on the structure and properties of substances in physics, biology, chemistry, materials, and other fields.  A microscope is also popularly called a magnifying glass because its main function is to magnify the object under observation.  According to the different imaging principles, microscopes can be roughly divided into three categories: optical microscope, electron microscope, and scanning probe microscope.  

Observing the microscopic world through a microscope is actually a kind of light image art, which must have a lighting source.  Due to the observation of a variety of objects, thousands of shapes, at the same time need to cooperate with different light source lighting to achieve observation effect, and therefore developed a variety of different microscopes corresponding to the observation of objects.  

2. What is a telescope?  

Magnifying instruments used to observe objects far from the observer are called telescopes.  A telescope is an optical instrument that uses concave and convex lenses to observe distant objects.  With it, people can see things where there is no place.  A telescope for viewing with one eye is called a monoculture;  Binoculars for two eyes are called binoculars.  A telescope usually consists of an objective lens, a rotating prism, and an eyepiece.  

The telescope is a kind of visual optical instrument used for observing distant objects. It can enlarge the small Angle of distant objects by a certain magnification so that it has a large Angle in the image space so that the objects that can not be seen or distinguished by the naked eye become clearly discernible.  Therefore, the telescope is an indispensable tool in astronomy and ground observation.  It is a kind of optical system through the objective lens and eyepiece so that the incident parallel light beam still remains parallel to exit.  

In daily life, telescopes mainly refer to optical telescopes.  But in modern astronomy, telescopes include radio telescopes, infrared telescopes, X-ray telescopes, and X-ray telescopes.

3. The difference between a microscope and a telescope  

Microscopes and telescopes are made up of two sets of convex lenses, both called objective lenses and eyepieces, but with different features from each other.  The objective lens of a microscope, an inverted magnified real image of an object at one and two focal lengths, is used to magnify the object at one time.  The object lens of a telescope, at a distance of twice the focal length, forms an inverted and reduced real image to bring distant objects closer to the eye.  In both cases, the eyepiece acts as a magnifying glass.  

The main differences between a microscope and a telescope are:  

Observe different objects: microscope is used to observe small objects or small parts of the instrument, the telescopic sickle is used to see distant objects.  

The principle is different: a microscope uses a convex lens close to the object to make it a magnified real image, and then another convex lens close to the eye magnifies this image again. Then very small objects can be seen.  A telescope uses light refracted through a lens or reflected by a concave mirror, to make it pass through a hole and converge into an image, which is then seen through a magnifying eyepiece.  

The structure is different: the microscope is composed of eyepiece, objective lens, coarse quasi-focal screw, fine quasi-focal screw, pressure clip, light hole, visor, converter, reflector, holding platform, mirror arm, mirror barrel, lens holder, concentrator, diaphragm.  The telescope consists of two sets of convex lenses.  Close to the object is called the objective lens, the focal length is longer;  The one near the eye is called the eyepiece and has a shorter focal length.
