Imaging performance of an ultra-precision machining-based Fresnel lens in ophthalmic devices

Autor: Syed Azkar Ui Hasan, Youngdurk Park, Hongseok Youn, Ho-Cheol Lee, Van Truong Vu

Publikováno v: Optics express. 29(20)

This study aims to resolve the trade-off between the constraints and capabilities of ultra-precision machining to achieve ophthalmic Fresnel lenses. A general Fresnel lens pattern has a narrow variable pitch and curved grooves. However, we obviate th
