Chocolate Terahertz Fresnel Lens

Abstract

Recent enormous development of 3D printing techniques gave the possibility of precise manufacturing of designed optical structures. This paper presents designing, manufacturing and the results obtained for chocolate Fresnel lens. Chocolate, similarly to wax, can be melted and used in the 3D printed form to create a terahertz (THz) optical element. Parameters of the chocolate lens are compared with the one made of wax. In simple applications both materials can be used as a cost-effective alternative for conventional optical materials used for THz range of radiation. Both lenses have been designed and compared for 140 GHz.
