Aluminum film is the only material with high reflectivity from ultraviolet to infrared. Both straight and bending loss of this kind of hollow waveguides are small.
铝膜是从紫外到红外都有很高反射率的理想材料，用它来研制的空芯光纤的直线损耗和弯曲损耗均较小。

Can meet the performance requirements of heat insulation and cooling, sunlight reflectivity and emittance are more than 80%3 of nano ATO is the infrared radiation material, and conductive material.
