Performance Enhancing
Reynard produces a wide variety of metallic mirror edge to surface coatings capabilities including aluminum, gold and silver providing a moderate level of reflection over an extremely broad spectral range. Most metals can be evaporated including gold, aluminum, silver, copper, nickel and many more, tend to be soft and need a dielectric coating for protection. Metallic mirror coatings have a broader reflection bandwidth compared to dielectric mirrors.
We can supply a variety of custom metallic mirror coatings for your specific application!
Custom prototypes to volume production are available.

Bare Aluminum Coating
Bare aluminum is very soft and scratches easily; therefore, it must be handled with great care. The reflectivity is approximately 88% in the visible wavelengths.
The graph above shows Percent Reflection vs. Wavelength – microns, ranging from 0.3 to 1.0 µm with reflection near 88–90% across the visible spectrum.
Protected Aluminum Coating
Protected aluminum mirrors are first coated with aluminum, then protected with silicon monoxide. The mirrors are usable from 400 nm to the far infrared. The reflectance is typically above 88% in the visible and above 96% in the far infrared. These mirrors are hard and durable. They meet all requirements of MIL-M-13508.
The graph above shows Percent Reflection vs. Wavelength – microns, ranging from 0.3 to 1.0 µm, with reflectance around 88–90% in the visible region.
