This paper describes the effect of tip radius on optical performance for fabricating Fresnel lens. We firstly designed Fresnel lens for uniform light distribution by backward design method and energy compensation method. To verify the effect of tip radius, simulation was conducted varying lens tip radius. Designed Fresnel lenses were replicated by UV imprinting and injection molding process using metal mold fabricated by direct machining. Lens profile fabricated by each process and optical performance with each fabricated lens were measured. We compared the results with simulation data, and analyzed the effect of tip radius.
