Aspheric mould design includes the top-down design and reversal design. In this paper, a new framework of reversal
design is proposed combining with cloud supported collaborative design (CSCD) based on aspheric measurement. The
framework is a kind of collaborative platform, which is composed of eight modules, including the computerized aspheric precision measurement module (CAPM), computer-aided optical design of aspheric lens system (CAOD),
computer-aided design of lens mould (CADLM), FEM(finite element method) simulation of lens molding module
(FEMLM), computer-aided manufacture of lens and moulds (CAMLM), measurement data analysis module (MDAM),
optical product lifecycle management module (OPLM) and cloud computing network module (CCNM). In this framework, the remote clients send an improved requirement or fabrication demand about optical lens system through CCNM, which transfers this signal to OPLM. In OPLM, one main server is in charge of the task distribution and
collaborative work of other six modules. The first measurement data of aspheric lens are produced by clients or our proposed platform CAPM, then are sent to CAOD for optimization and the electronic drawings of lens moulds are generated in CADLM module. According the design drawings, the FEMLM could give the lens-molding simulation
parameters through FEM software. The simulation data are used for the second design of moulds in CADLM module. In this case, the moulds could be fabricated in CAMLM by ultra-precision machine, and the aspheric lens could be also
produced by lens-molding machine in CAMLM. At last, the final shape of aspheric lens could be measured in CAPM and the data analysis could be conducted in MDAM module. Through the proposed framework, all the work described
above could be performed coordinately. And the optimum design data of lens mould could be realized and saved, then shared by all the work team.
