Derive thin lens formula for convex lens
WebWe take the limit of t → 0 to obtain the formula for a thin lens. To derive the thin-lens equation, we consider the image formed by the first refracting surface (i.e., left surface) and then use this image as the object for the second refracting surface. http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/lenseq.html
