Microscopic imaging technology with electrowetting liquid lens

The electrowetting liquid lens is increasingly favored by researchers due to its tunable focal length, fast response, convenient operation, and low power consumption. It can solve some technical problems such as mechanical jitter and discrete zoom in microscopic imaging systems, thus promoting the intelligence and lightweight of these systems. Firstly, the basic concept of and the research on electrowetting liquid lenses are described. Then, the latest research on the microscopic imaging technology with the electrowetting liquid lens is reviewed. Two microscopic imaging technologies, continuous optical zoom and axial scanning, are introduced in detail. Finally, the prosects and challenges of the microscopic imaging technology with the electrowetting liquid lens are presented.
