- Providing over 86% reflectivity
Bare Al can provide over 86% reflectivity from NUV to MIR wave band. However as Al will be slowly oxidized and result a significant reduce of reflectivity in UV, as well as little scattering in the whole spectrum. Therefore, we advice add a protective film, it doesn’t only address the above issues but also remarkably improve abrasive resistance, in that case coating is more protective during cleaning and handling.
