Abstract
A compact, lightweight, portable optical assembly comprising: a platform; and a plurality of optical elements mounted to the platform; wherein the plurality of optical elements are optically connected to one another with free-space couplings so as to form an optical circuit; and further wherein the platform is sufficiently mechanically robust so as to maintain the free-space optical coupling between the various optical elements. A method for making a compact, lightweight, portable optical assembly, comprising: providing a platform; and mounting a plurality of optical elements to the platform; wherein the plurality of optical elements are mounted to the platform so that they are optically connected to one another with free-space couplings so as to form an optical circuit; and further wherein the platform is sufficiently mechanically robust so as to maintain the free-space optical coupling between the various optical elements.
