Abstract	This paper presents design of a refractive-diffractive hybrid lens for use in micro optical scanning systems. To achieve the target focal length with minimized aberration, the refractive lens was optimally designed with consideration of reducing transverse ray aberration. The diffractive efficiency was calculated in terms of depth and period of the Fresnel pattern via rigorous coupled wave-analysis (RCWA). The geometry of the V-shaped diamond tools limits the depth of Fresnel edge of the diffractive lens due to the interference, which eventually determines the whole size of the lens. In this study, two types of hybrid lenses for micro scanning system were compared and designed in consideration of optical performance and machining limit. Therefore, the designed diffractive lens was optimized for 300 μm focal length with minimum aberration. The depth of Fresnel edge and the diameter was determined to be 0.94μm and 423.4μm within the machining limit, respectively. The lens base mold was fabricated using a 5-axis ultraprecision machine, and the lens was imprinted through a hot embossing process. The measured focal length and the calculated NA are 336μm and 0.63 respectively. Lastly, Imaging tests and diffractive efficiency are measured to evaluate the optical performance of the micro-hybrid lens.
