Laser BlackLaser Black
A velvet-like metallic oxide, Laser Black is an inorganic coating that will not out-gas. It can be applied to any substrate that can withstand 100C. It has been said that, “It seems to swallow light.”

A gold coating can range from matte to bright finish. It demonstrates good corrosion resistance, has high tarnish resistance and provides a low, electrical contact resistance. It also acts as a good conductor. Gold has a high reflectance capability for infrared light and in the form of Laser Gold, which exhibits the hightest IR reflectivity done by any electroplating process.

Rhodium is a chemical element that is a rare, hard transition metal that can be found in platinum ores. It is used in alloys and acts as a catalyst with platinum. It is one of the most expensive precious metals in the world. Rhodium is a durable metal that exhibits higher reflectance in visible light. It has both a higher melting point and lower density than platinum and can’t be attacked by acids.

Cadmium is a chemical element with the symbol Cd and atomic number 48. The soft, bluish-white transition metal is chemically similar to the two other metals in group 12, zinc and mercury. Similar to zinc it prefers oxidation state +2 in most of its compounds and similar to mercury it shows a low melting point for a transition metal. Cadmium is a relatively abundant element.

Electroformed IR Countermeasure Device

Electroforming is the process of fabricating a part from the plating itself. A shaped mandrel is plated long enough to build up a “stand alone” thickness. The mandrel is then removed by melting, chemically etching or exploiting differences in thermal coefficients of expansion between the electroformed part and the mandrel.

Because of Epner’s critical role in the coating of optics, our polishing capability is frequently confused for optical polishing or lapping. Polishing done at Epner Technology is probably better characterized as buffing.
