title: Experimental method of determination of parameters of cemented doublet.
abstract: This work analyzes a method to determine the internal parameters of an optical system of a classical cemented doublet or a three-element tunable-focus lens (a tunable-focus doublet), which is an equivalent of the classical cemented doublet. The method is noninvasive, and the parameters are calculated without any damage or dismantling of the lens.
