Product Drawing

Mid-Infrared-Enhanced Gold Mirrors offer >98% average reflectance and >95% absolute reflectance between 2 µm to 20 µm, without suffering losses found with protected gold mirrors. The overcoat on these mirrors allows them to perform better than our unprotected gold mirrors in the mid-infrared (MIR), while offering resistance to physical damages.

The plot to the right shows the measured reflectance of this coating as a function of wavelength. The shaded region denotes the range over which we recommend using these optics. Data was obtained using at a 45° angle of incidence.
