The paper aims to create a unit using Fresnel lenses. This module consist of an arrangement of planar-convex Fresnel lenses. made of methyl polymethacrylate. mounted in a hexagonal raster and bent to form a dome for collecting and amplifying solar radiation at several focal points and with the possibility of adjusting the focal distance. https://www.secondgearwncers.shop/product-category/gifts-magnets/
