Mirrors- Metal, Protected & Enhanced

Metal Coatings:  In some cases it makes much more sense to coat a simple metal coating rather than a complex all dielectric coating.  Although metals tend not to have as high reflectivity and laser resistance; a metal coating is more cost effective, induces less polarization effects, and typically covers a broader reflectivity band.  Thin film accuracy and rate control for a particular metal type is crucial.  Each material requires a different technique in order to maximize the reflectivity benefits for that particular metal.  In addition, different bonding and protection layers may be required for each metal type.  Although it may seem straight forward, these things are all carefully dialed into our processes from years and years of experience.  You might say we have learned what works by trying what has not.  Thankfully, we have our own Environmental Test Lab and can qualify the weather resistance for every coating formula.  All our protected Mirrors Pass MIL-C-13508C. We coat just about every type of metal that exists. Below are only a few examples of common coatings we do here at Cascade
