Multilaminar aluminium reflector

摘要

The Spanish company Alucoil has developed a PVD-coated aluminium reflector under the name Almirr. With its highly reflective coating, which has a specular reflec- tivity of 89 % across the solar spec-trum, Almirr reaches reflectance levels similar to those of conventional glass reflectors. The reflective layer is protected by a ceramic coating.
