| Abstract Scope |
Additive manufacturing processes are promising in fabricating optical prototypes, including the production of contact lenses, waveguides, and Fresnel lenses used in various applications. Our study presents a novel fabrication method for high-quality Fresnel lenses through vat photopolymerization 3D printing method. Here, 3D printing process is integrated with micro/nanostructures fabrication process to produce components with desired micro or nanostructures in a single step. This straightforward approach resulted in embedding a micro pattern (5µm features size) on Fresnel lens flat surface to achieve light focusing and rainbow holographic effect simultaneously by responding to three different lasers. Interestingly, the holographic effect resulted in closer focal points to the designed value, and overall, lenses achieved focusing with ≤ 8 mm deviation without post-processing. The holographic Fresnel lens is highly desirable in image-based mechanoluminescence sensors. Thus, the vat photopolymerization-based 3D printing process can produce normal and holographic Fresnel lenses vital in optical sensing and communication. |
