Micro-embossing Equipment for Precision Optical Microstructures

Optical components are conventionally moulded by infrared heating in a hot compression process, which takes a long time in heating up and cooling the materials while consuming of a lot of electric power. Our micro-embossing equipment can produce micron-level micro-structural optical components in glass with less electric power. It can rapidly heat up glass and measure the temperature of workpieces in situ using the graphene coating with silicon as the die material. It solves the key problems in conventional production process, e.g. slow packaging cycle, difficulties in mould cavity melting and moulding pressure accuracy control. The equipment enables rapid and accurate impression of small aspheric lens and fine optical microstructures such as microlens array.
