Temperature effect on the deformation and optical quality of moulded glass lenses in precision glass moulding

The aim of this study was to thoroughly investigate the effect of temperature on the deformation behavior and optical performance of moulded glass in a nonuniform temperature field. Experiments and numerical simulations were used to analyze how different temperature gradients distributed across a glass cylinder affected the deformation behavior of the moulded glass. Additionally, the imaging quality of the moulded glass lens was detected using...
