Our protected aluminum, silver, and gold coatings exhibit exceptional broadband reflectance and are practical for many applications that are insensitive to the wavefront of a beam. Other typical uses for these mirrors include single-use applications where the experiment itself damages the mirror. A variety of diameters and square sizes are offered, including an 8" x 8" protected aluminum version. Please see the Specs tab for more details on these mirrors.
The shaded regions in the graphs denote the ranges over which we guarantee the specified reflectance. Please note that the reflectance outside of these bands is typical and can vary from lot to lot, especially in out-of-band regions where the reflectance is fluctuating or sloped. Protected Aluminum Coating (450 nm - 20 µm)
Protected Silver, -P01 Coating (450 nm - 20 µm)
Protected Gold Coating (800 nm - 20 µm)
![]() Our round protected aluminum mirrors are available in Ø1/2", Ø1", and Ø2" sizes, and exhibit average reflectance in excess of 90% in the 450 nm to 2 µm range and 95% in the 2 µm to 20 µm range. A protective SiO2 overcoat is layered over bare aluminum, creating an oxidation-resistant surface which has a smaller chance of tarnishing than protected silver in a high humidity environment. The graph to the right shows these mirrors' reflectance at a 45° angle of incidence (AOI). The shaded region denotes the spectral range over which we recommend using these optics. See the Graphs tab above for 12° AOI data.

Silver is an ideal choice for high reflectance from 450 nm to 20 µm. In order to protect the mirrors from oxidation, they have an overcoat of SiO2. Though the overcoat helps to protect silver from tarnishing, high humidity environments should be avoided. The graph to the right shows these mirrors' reflectance at a 45° angle of incidence (AOI).
