The invention provides an optical element molding method based on a
graphene-like electrothermal film. The method includes the following steps: a surface of a pressing surface of a first pressing moldis provided with a
microstructure mode cavity, and a surface of the
microstructure mode cavity is plated with the
graphene-like electrothermal film; the
graphene-like electrothermal film is energizedand heated; the heat-generating graphene-like electrothermal film and an optical element blank material are contacted; after receiving the heat from the graphene-like electrothermal film by heat conduction and
softening and deforming, the micro-structure mode cavity is filled with the optical element blank material; and the optical element blank material deformed according to the
microstructure mode cavity is cooled and shaped by a
cooling channel in a second pressing mold to form a lens. The method adopts the graphene-like electrothermal film for local heating, has high heating speed and
high energy utilization rate, and the graphene-like electrothermal film has a
low friction coefficient, can effectively prevent the adhesion between the blank material and the mold, and ensures the high-quality, high optical precision
processing of the optical element surface.
