Open focal length of two lenses in contact. Find their equivalent focal length. 14For combinations of two thin lenses in contact we have seen that the focal length of the combi-nation is given by an expression involving the individual focal lengths. 1f 1f 1 1f 2. Check also: lenses and focal length of two lenses in contact 11When two converging lenses of same focal length f are placed in contact then the focal length of the combination is a f b 2f c f2 d 3f.
If two lenses are considered as equivalent to a single lens of focal length f then. 1F 1f 1 1f 2 Combined focal length F.

A ray of light from the object after passing through the combination of lenses the refronted light ray meet at I.
The common focal length for a system where two thin lenses are sharing an axis are kept in contact with each other is given by the following formula. F 2 is the focal length of the second lens. 27Two lenses are placed in contact with each other and the focal length of combination is 80 cm. Since 1f is the power of a lens it can be seen that the powers of thin lenses in contact are additive. 3Consider two lenses A and B of focal length f 1 and f 2 placed in contact with each other. The image of point object O will be at I 1 formed by lens A which act as a virtual object for second lens B producing the final image at I.
