Laser Black
Laser Black is a multi-layer metallic oxide. Its deep velvety-black surface is somewhat fragile since it achieves its remarkable absorption by creating a micro-dendritic structure on the optical surface (see Laser Black SEM Photo). Unfortunately, these dendrites will show evidence of being touched, however the overall performance of the surface will not be degraded if this “touching” is performed in a small area. Being an inorganic coating, Laser Black does not outgas, and when vibrated ultrasonically in acetone, shows no flaking or chipping.
- Specifying Laser Black
"Laser Black per Epner Technology spec 3688"
Your product will be plated with a duplex copper coating, and then a velvet-like copper oxide is formed. A fifty year old process was significantly modified in ETI's Lab in order to achieve a coating that one expert said, "swallows light." Under certain conditions a roughening of the substrate may take place prior to copper plating.
