Abstract

A formula is derived from meridional ray tracing for finding the refractive-index of a lens in terms of its construction parameters. Also, an experimental technique is presented as well as its accuracy for the determination of the refractive-index of the lens for the wavelength of a He-Ne laser (6328 A).
