—Development of the optical technology isextremely important in the field of science research,industrial production and daily appliances. Although a lot ofresearches have conducted in the area of processing opticallenses, very few attempts have been made at the quality ofoptical lenses. We established a Process Capability AnalysisModel (PCAM) to discover the ineffective areas of qualityitems. In this paper, the PCAM flow is used to evaluate theprocess capability of hexagonal infrared optical lenses. As aresult, we discovered the lens’ diameter is qualified, but thetotal thickness is not.
