What does the material of liquid lens mean?

Liquid lens refers to a lens with a certain shape made of polymer material, which can change its shape at a specific temperature, thus realizing the change of focal length. The material of liquid lens usually adopts polymer materials, such as polyolefin, aromatic polyimide and so on. These polymer materials have good heat resistance and high temperature stability, and can maintain their mechanical and optical properties at different temperatures.

In recent years, the development of liquid lenses has received extensive attention. Liquid lens is widely used in various optical systems because of its excellent performance and adjustable focal length. For example, in the field of UAV and robot manufacturing, liquid lens can achieve autonomous focusing, making the shooting effect of robots sharper. In addition, liquid lenses are also used in telescopes, optical instruments, lasers and other fields.

Although the application prospect of liquid lens is broad, the manufacturing and cost of liquid lens are still high. In order to solve this problem, scientists are constantly studying the manufacturing technology and material selection of liquid lens, trying to make it lower cost and better performance. It is expected that more liquid lenses will be popularized and commercialized in the future. The progress of material selection and manufacturing technology of liquid lens will also promote the more efficient and stable development of optical instruments.
