Meniscus cylindrical lens
Meniscus cylindrical lenses feature a convex cylindrical surface on one side and a concave cylindrical surface on the other. Through matched curvature design, they can achieve focusing or diverging functions while effectively reducing spherical aberration and astigmatism, delivering better image quality than single-surface designs. Ideal for precision optical systems requiring high imaging quality, they are widely used in high-end laser scanning and medical optics applications.
