Optical microscope (microscope for short), as its name implies, is an optical instrument that displays the microstructure of an object through optical magnification and is composed of one or more lenses combined. Microscope imaging is an art of light. When combined with various light sources, different types of images can be formed, and various types of microscopes have evolved.

In the early days of the development of microscopes, the optical technology was underdeveloped. The microscopes made at that time were designed with a single-optical-path straight tube and could only use one eyepiece for observation, so they were often called monocular microscopes. Monocular microscopes are limited by the electronic, mechanical, and information technologies at the time, and usually have the following characteristics: ①Use reflectors to reflect natural light to provide illumination; ②Coarse and fine quasi-focus spirals use separate handwheels; ③The stage is Single-layer structure, and immovable.

2. Binocular biological microscope (the second stage of microscope development 2.0)

After making significant progress in optical imaging, people focused on the improvement of microscopes on the acquisition of microscopic images. People perform light splitting again on the binocular light path signal to form a trinocular observation tube, and then install the camera collector on the trinocular observation tube to obtain a microscopic image. Since then, microscopic images have gradually become an important means for people to record original information. Compared with the aforementioned microscopic painting, this method of obtaining microscopic images is more accurate, more efficient, and more advanced.

4. Digital liquid crystal microscope (the fourth stage of microscope development 4.0)

The development of the microscope to the fourth stage, more consideration is the use of innovation, ease of use, and convenience. At this time, the digital LCD microscope has the functions of a biological microscope and a physical microscope. It also adds a microscopic measurement function. At the same time, it can have a built-in high-capacity lithium battery (for outdoor use) and the function of storing data in a U disk.
