Energies, Vol. 12, Pages 2795: Design, Manufacturing and Characterization of Linear Fresnel Reflector`s Facets (Energies)

This paper presents a procedure for making facetted mirrors to use in linear Fresnel reflectors, considering the design of the transversal geometry, materials, and structure configuration. Four different assemblies of the structure that supports and shapes the mirror are documented and evaluated. An assembly that implies a curved, pleated aluminum rectangular plate with a thin silvered-glass mirror vacuum glued to the plate is defined as the optimal. The geometrical quality of the chosen mirror facet’s configuration is accomplished by photogrammetry.
