Abstract

This paper explores the use of a novel monitoring method in the manufacture process of optical microelements by means of controlled heating with laser. With this method, based on photoelasticity techniques, it is possible to display the mechanical stresses that forms the microelement and its optical properties. It is defined a new parameter, Relative Stress Area (RSA), which quantify the mechanical stress of a microelement during its creation process, make the comparison between different microelements possible. Also permits to display and quantify the three stages in the fabrication process: creation, balance and cooling. Different microlenses has been monitored and the results are presented in same images and graphs.
