Numerous recent technological breakthroughs suggest that microoptics will represent one of the key enabling technologies of the future. Because of their active role in the control of naturally or artificially produced light, micro-optical components/systems have found a wide applicability in many economic sectors including but not limited to telecommunication, transportation, defense, consumer goods or healthcare. Regardless of their geometric complexity, microoptical components have to be produced in large quantities and at extremely high levels of accuracy, a goal that is generally achieved through high precision injection (micro)molding. However, the conventional techniques used so far in fabrication of molds/mold masters – generally based on material removal, lithographic, or laser ablation processes – tend to be costly and also cannot be used to produce certain types of microoptical surfaces, such as those characterized by microstructured and/or periodic patterns. To address this, the current proposal will be focused on the development of a comprehensive platform to integrate optical design/analysis with high performance five-axis computer numerically-controlled (CNC) single point cutting inverted cutting technology in an attempt to provide more effective means to fabricate this special class of microoptical components that are characterized by superior optical efficiencies. The knowledge to be generated in the framework of the proposed research is expected to facilitate downstream developments capable to position Canadian manufacturers among world leaders in fabrication of microoptical components. The trainees to become involved in the proposed research are expected to acquire a critical set of skills required for further promotion and development of this niche, but presently underrepresented sector of Canadian economy.

最近的许多技术突破表明，微光学将代表未来的关键使能技术之一。由于它们在控制自然或人工产生的光中的积极作用，微光学组件/系统在许多经济部门中具有广泛的适用性，包括但不限于电信、运输、国防、消费品或医疗保健。无论其几何复杂性如何，微光学元件都必须以极高的精度大量生产，这一目标通常通过高精度注塑（微）成型来实现。然而，迄今为止在模具/模具母模的制造中使用的常规技术-通常基于材料去除、光刻或激光烧蚀工艺-往往是昂贵的，并且也不能用于生产某些类型的微光学表面，诸如以微结构化和/或周期性图案为特征的那些微光学表面。为了解决这个问题，目前的建议将集中在一个综合平台的发展，集成光学设计/分析与高性能五轴计算机数控（CNC）单点切割反向切割技术，试图提供更有效的手段来制造这种特殊类别的微光学元件，其特点是上级的光学效率。在拟议的研究框架内产生的知识预计将促进下游发展，使加拿大制造商在微光学元件制造方面处于世界领先地位。参与拟议研究的受训人员预计将获得进一步促进和发展这一利基市场所需的一套关键技能，但目前这一市场在加拿大经济中的代表性不足。
