The double convex lens is an optical lens with convex surfaces on both sides. It is mainly used for beam convergence, image magnification, and light path focusing. Due to its symmetrical structure and efficient light energy collection capability, it becomes a fundamental component of optical systems.
Efficient beam convergence: Symmetrical optical path.
Multifunctional optical control: Imaging magnification.
Material compatibility with coating: A wide range of material and coating options are available.
