Meniscus Lenses
Meniscus lens is a lens composed of two curved surfaces, with one side convex and the other side concave.
It controls the convergence or divergence of light while reducing spherical aberration, making it suitable for optical systems that require high-precision focusing or diffusion.
There are convex meniscus and concave meniscus types, and they are selected according to the application.
