Abstract
A method for optical production includes fabricating an array of optical elements on a transparent planar substrate, the array having opposing first and second surfaces parallel to the planar substrate. For each of the optical elements, a respective housing contains a notch of a predefined width. The first surface of the array is etched so as to form, on each of the optical elements in the array, a respective protrusion having a transverse dimension selected so as to fit into the width of the notch, the second surface of the array is diced through so as to singulate the optical elements. Each of the singulated optical elements is inserted into the respective housing such that the respective protrusion is contained in the notch.
