Paper Abstract

Dual band transparent conductive coatings for the visible and 3-5 micrometers range have been developed on sapphire substrates. The conductive layer consists of indium oxide, deposited in reactive oxygen ion plasma. The typical average transmission of a coated element is about 72% 3.6-4.2 micrometers and about 82% 0.5-0.9 micrometers . Sheet resistance is about 40 ohm/square. The coatings are highly durable and withstand MIL-C-675C tests. Coating transmission in both spectral ranges remains constant in the temperature range -140 degree(s)C - +160 degree(s)C . Sheet resistance increases by about 30% when heating from room temperature to 250 degree(s)C.
