T-ME2-G01 - Ø2" Round Protected Aluminum Mirror, 3.2 mm Thick
T-ME2-G01 - Ø2" Round Protected Aluminum Mirror, 3.2 mm Thick
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.
