Precision Glass Molding of Micro Fresnel LensTraduire cette page

In the glass molding experiments, the WC (tungsten carbide) molding dies of fresnel shape were used and the dies were ground by using the proposed grinding method with vertically controlled grinding spindle and the disk type wheel of knife edged shape. Then micro glass fresnel lenses were pressed in trial and the optimum press load and press temperature were studied experimentally. The ...
