The diverging lens also known as negative lens. Diverging lenses come in a few different shapes, but all diverging lens are the negative sign signifies that the image is virtual. A lens is a transmissive optical device that affects the focus of a light beam through refraction. The distance from this point to the lens is also known as the focal length, though it is negative.Convex-concave (meniscus) lenses can be either positive or negative, depending on the relative curvatures of the two surfaces.
