Nowadays, there is a huge demand for small lens with high resolution in advanced optical systems. However, the production cost using conventional technology is high, yet the lens produced has relatively low precision.
In view of this, Prof. Lee Wing-bun and Dr Li Li-hua from the Department of Industrial and Systems Engineering has adopted a novel molding design with graphene-like coating and self-developed heating technology to produce micro embossing equipment for production of micron-level microstructural optical components in glass. The equipment could heat up the optical glass precisely and quickly with low energy consumption, while reducing thermal expansion and deformation of the mold.
The invention was recently awarded a Gold Medal at the 46th International Exhibition of Inventions of Geneva 2018. It can be widely applied in various fields – from astronomy, national defence, medical scanning, to consumer products such as cameras and mobile phones. Details>>
