Product Drawing

Protected gold coatings are ideal for use over the entire IR range, with an average reflectance in excess of 96% for 800 nm - 20 µm. A protective SiO2 overcoat is layered over the gold to make it damage resistant and easy to clean.

The plot to the right shows the measured reflectivity of protected gold 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.
