which gives the point O. Ifthe curvatures are unequal, the triangles COA and COA are similar, andeither CO or CO may be found, and therefore also the point O. In double concave or meniscus lenses the optical centre may bedetermined by the same construction. In lenses with a plane face this pointis… … F?- 545 Fig- 546 in all cases here considered the thickness of the lens is supposed to beextremely small, we may, in determining geometrically the positions ofimages, consider the optical centre to lie halfway between the two surfacesof the lens, and that rays passing through the optical centre…
