Gold Mirrors with Size (mm) 5.0 x 5.0mm

Protected gold is ideal for applications requiring high reflectance in the NIR and IR wavelength range. Since a durable coating is necessary for many applications, we offer our gold mirrors with a protective overcoat. This protective dielectric overcoat is layered over the gold to help protect it from damage and make cleaning easier. Like other mirrors with metallic coatings, these mirrors are relatively insensitive to angle of incidence.
