Meniscus (Material: BK7)

The Positive Meniscus (Convex-Concave) Lens is an essential optical component designed to optimize performance by minimizing spherical aberration. These lenses are characterized by their unique shape, featuring a convex surface on one side and a concave surface on the other. This design is particularly beneficial when the lens is ...
