The plano-convex lens is a type of optical lens with a single convex surface on one side and a single flat surface on the other. It is mainly used for beam convergence, collimation and imaging. Due to its simple curved surface structure and efficient optical performance, it has become a core component in laser systems, imaging equipment and lighting design.
Efficient beam convergence.
Multifunctional application: It can both direct light and serve as a simple magnifying glass.
Material compatibility with coating.
