Metallic Mirrors consist of a good combination of performance and value for general purpose applications. They operate over a very broad spectral range from UV to visible, and visible to near – and mid-IR. They are relatively insensitive to angle of incidence and polarization, and their relatively wide bandwidth and high reflectivity makes them ideal for applications like spectroscopy.
Round or rectangular shape mirrors with flat or spherical surface, coated with protected gold, protected silver or protected aluminum. Metallic mirrors are widely used due to a moderate level of reflection over a very broad spectral range. Protected gold coatings have the highest reflectance in IR, protected silver is the most efficient in VIS, while protected aluminum is an economical reflector over entire 300nm-IR range.
