Cylindrical mirror is a special optical component, and its working principle and application scenarios are significantly different from traditional spherical mirrors.

A microscope is a precision measuring instrument that allows students to observe extremely small organisms and study their microbial morphology. The main body of the microscope is composed of optical and mechanical parts, among which the optical part is the most important. The optical part of a microscope mainly consists of an objective lens and an eyepiece. By combining the two, a good observation image is formed.

The objective lens is the most important optical component of a microscope, which uses light to image the object for the first time. Therefore, it directly affects the quality of imaging and various optical technical parameters, and is the primary standard for measuring the quality of a microscope.

A Micro Lens Array is a two-dimensional array composed of many tiny lenses. Each micro lens can focus the incident light onto a small area, and by controlling the focal length and position of each micro lens, control and adjustment of the light can be achieved.

Endoscope is a medical tool used to examine organs and tissues inside the human body. It consists of a soft long tube with a small light source and camera at one end, which can transmit images to a display for doctors to observe.

Endoscope is a medical device that can enter the body through natural channels or incisions for examination, treatment, and other procedures. According to different purposes and structures, endoscopes can be classified into various types.
