Birefringence measurement for validation of simulation of precision glass molding process

What is it about?

This article is all about simulating residual stress in molded glass lens. Experimental techniques to quantify the material properties, thermal boundary conditions required for simulation is described. Industrial standards specify the quality of the molded lens in terms of birefringence. Methodology to post-process and quantification of residual birefringence from the simulation is elaborated. The simulation tool is verified with measured birefringence.

Why is it important?

The outcome of the research work will assist glass molding industries to design the process parameters for fabricating high quality optical glass lens without undergoing conventional trial and error experiments. The quality of the lens products can be directly quantified from simulations without performing any experiments. Money, Material and Minutes can be saved by the glass molding industries for the optimal bulk production of lenses thereby reflecting on the final business profits.
