This paper presents a roll-to-plate hot embossing process (R2PHEP) for precision manufacturing of optical microstructures on polymethylmethacrylate (PMMA) surface. The viscoelasticity of PMMA at embossing temperature is described by the General Maxwell model. The finite element numerical simulations of R2PHEP are carried out to optimize the process parameters, including mold temperature, roller radial displacement, and mold feed rate. The optimized parameters are used in the R2PHEP to fabricate the desired optical microstructures. The results show that R2PHEP is capable of precision manufacturing of complex and high precision optical microstructures on PMMA surfaces, making it a promising technology for efficient preparation of optical microstructure components.
