Spherical Aberration

• A Closer Look at Our 100 mm Meniscus Lens

  Oct 27, 2026

  A meniscus lens is an optical part with one convex surface and one concave surface. It looks like a crescent. It has two types: positive and negative. A positive meniscus lens gathers light together. A negative meniscus lens spreads light apart. The type depends on the difference between the two surface curvatures. How Lens Curvature Affects Optical Performance One of the key advantages of meniscus lenses is their flexibility in controlling optical aberrations. By carefully selecting surface curvatures and lens orientation, optical designers can reduce spherical aberration under certain conditions and improve overall system performance. However, a meniscus shape does not automatically guarantee better optical performance. Factors such as focal length, aperture, refractive index, and the s...
