Lens curvature testing. Curvature of an optical lens being tested with a laser. The lens (centre) is being held in a mount, and laser light (red) is being shone through it to test its optical properties, such as curvature. The degree of curvature of a lens determines how it bends light rays passing through it, and where the focal point of the lens is.
