Coating Metal Optics: Getting From a “No” to a Go!

go from a no to a go

Have you been getting a “no bid” response from coating houses when they do not apply coatings to metal optics?

We can help with difficult to source metal and dielectric coatings!

Optical components that require a metal coating and have the added challenge of a non-flat shape can be demanding for coating houses that are not set up to handle this type of work regularly. Fortunately, we have processes that allow us to coat metal reflective coatings (gold, silver, aluminum) and even dielectric mirror coatings. Our modern and high-capacity coaters are designed to handle spinners, flats, convex, concave, or complex shapes, such as diamond-turned or molded optics.

Coating Types offered:

  • Aluminum (Al)
  • Gold (Au)
  • Silver (Ag)
  • Chrome (Cr)
  • Copper (Cu)
  • Inconel
  • Titanium (Ti)
  • All Dielectric
