Abstract: A fiber-optic two-color pyrometer with high spatial and temporal resolution has been applied to measure temperatures at an external turning process. Different measurement positions have been ...

Abstract: Compression molding is an effective high volume and net-shape fabrication method for aspherical lenses and precision glass optical components in general. Geometrical deviation (or curve change as ...

Abstract: Compression molding of glass optical components is a high volume near net-shape precision fabrication method. Residual stresses incurred during postmolding cooling are an important quality indicator ...
