What Is Microscope

A microscope is an optical instrument composed of a lens or a combination of several lenses, and it is a sign that human beings have entered the atomic age. A microscope is an instrument mainly used to magnify tiny objects for the human eye to see.

Microscopes can be classified into polarized light microscopes, optical microscopes, electron microscopes, and digital microscopes according to the microscopic principle.

Usually consists of optical part, lighting part and mechanical part. Undoubtedly the optical part is the most critical, it consists of eyepiece and objective lens. As early as 1590, Dutch and Italian spectacle makers had created microscope-like magnifying instruments. There are many types of optical microscopes, mainly including bright field microscope (ordinary optical microscope), dark field microscope, fluorescence microscope, phase contrast microscope, laser scanning confocal microscope, polarizing microscope, differential interference contrast microscope, and inverted microscope.

Electron microscopes have basic structural features similar to optical microscopes, but they have much higher magnification and resolution capabilities than optical microscopes. It uses electron flow as a new light source to image objects.

Portable microscopes are mainly an extension of the series of digital microscopes and video microscopes developed in recent years.
