与单线透镜甚至显微镜物镜等传统光学系统相比，先进的光学设计有助于开发出高效光学镊子的特性。我们提出了一种光学装置，提供针对大捕获力优化的定制强度分布。光学设计概念结合了折射双轴和反射抛物面聚焦镜。轴轴的排列创造了一个环形场分布，从而为系统中心额外的集成观测光学清理了空间。最后通过抛物面环形反射镜将光束聚焦到所需的强度分布。该系统的紧凑实现可能为光学镊子在生产工业和微纳米组装等领域的应用开辟新的领域。
Compared to conventional optics like singlet lenses or even microscope objectives advanced optical designs help to develop properties specifically useful for efficient optical tweezers. We present an optical setup providing a customized intensity distribution optimized with respect to large trapping forces. The optical design concept combines a refractive double axicon with a reflective parabolic focusing mirror. The axicon arrangement creates an annular field distribution and thus clears space for additional integrated observation optics in the center of the system. Finally the beam is focused to the desired intensity distribution by a parabolic ring mirror. The compact realization of the system potentially opens new fields of applications for optical tweezers such as in production industries and micro-nano assembly.
