Coatings

Ferson Technologies can provide coatings to support numerous coating requirements for the optical components produced. We can coat, perform testing for spectral, adhesion, durability, as well as temperature and humidity. Our coatings also meet many damage threshold specifications. We will coat optics we manufacture or coat customer provided material. We will provide a custom coat to your specification or offer our own designs.
