Define the Optical Centre of a Spherical Lens
In most cases, a lens with converging light will be followed by a lens with diverging light, which will subsequently be followed by a lens with converging light. The amount of magnification of the picture may be changed by moving the first lens closer to or further from the thing being photographed.
By shining light through the first lens and then the divergent lens, the picture that was before inverted may now be seen correctly. After passing through a concave lens, a ray of light that is perpendicular to the major axis would split into two separate rays.
However, when we create these rays in reverse, they will appear to converge at a point that is referred to as the focus. Because the lens causes the light beam to branch out in several directions, we refer to it as a diverging lens.
The optical centre of the lens is either the point that sits on the primary axis through which a ray of light may travel without being affected in any way, or it can be described as the point in the middle of the lens through which a ray of light can pass without being affected in any way.
The optical centre of a lens is the point on its primary axis through which light flows without deviation.
