Description

A laboratory optical microscope

technical field

The utility model relates to the field of optical microscopes, in particular to an optical microscope for laboratories.

Background technique

A microscope is a sophisticated optical instrument with a history of more than 300 years. Since the invention of the microscope, people have seen many tiny organisms and the basic unit of organisms—cells that could not be seen in the past. At present, there are not only optical microscopes that can magnify more than a thousand times, but also electron microscopes that can magnify hundreds of thousands of times, so that we have a further understanding of the laws of life activities of organisms. Most of the experiments stipulated in the biology teaching syllabus of ordinary middle schools are completed through microscopes. Therefore, the performance of microscopes is the key to doing well in observation experiments.

The existing optical microscopes have certain disadvantages when using them. First, the eyepieces of the current microscopes face up. When observing the target, the staff need to stand to observe, which is very inconvenient. Working for a long time will make the workers very tired, and the structure of the microscope It is relatively fixed, and the height of the equipment cannot be adjusted, which causes inconvenience to the observation work. In addition, microscopes often use slide clips to fix the slides, and the slides are easy to move, which has a certain impact on the observation work in the laboratory. , we present an optical microscope for laboratory use.
