WebOct 28, 2024 · The thin lens equation has a sign convention. A positive focal length means the lens is a converging or convex lens, and a negative focal length means that the lens is diverging or concave. WebConvex-concave (meniscus) lenses can be either positive or negative, depending on the relative curvatures of the two surfaces. A negative meniscus lens has a steeper concave surface (with a shorter radius than the convex surface) …

WebHence, the replicated formula will be. u1 f = 1 v + 1 u u 1 f = 1 v + 1 u. "The primary use case of the "concave lens" as the "negative focal length" is implicated in the length.
