Optical Centre Of Lens. PPT LENSES PowerPoint Presentation, free download ID1939318 The optical centre of the lens is defined as the point which lies on the principal axis through which the rays of light pass without any deflection The distance between the optical centre and focal point is called the focal length

The optical center ensures that light converges correctly onto the retina Once a thick lens is considered then the concept of the optical centre of a lens ceases to be useful

The Centre of curvature is the centre of the sphere whose surface the lens is a part of The principal axis can still be defined but a ray inclined to the principal axis will undergo two refraction's, one entering the lens and the other leaving the lens. The optical center is crucial because it is the point through which incident rays travel undeviated.

Explain the optical centre of a lens with the help of proper KnowledgeBoat. Once a thick lens is considered then the concept of the optical centre of a lens ceases to be useful Or it can be defined as the central point of the lens through which a ray of light passes without suffering any deviation.
