Each surface can be convex (bulging outwards from the lens), concave (depressed into the lens), or planar (flat). The line joining the centres of the spheres making up the lens surfaces is called the axis of the lens. Typically the lens axis passes through the physical centre of the lens, because of the way they are manufactured. Lenses may be cut or ground after manufacturing to give them … red cap gun

Spherical surface lens

WebA spherical lens is a transparent glass bounded by two spherical surfaces. In refraction, light changes its direction and moves away from the normal lens. This occurs as light travels from a denser medium to a rarer medium. Refraction by spherical lenses makes the incident ray of light to switch direction and move closer to the normal lens. WebSummary.
