Transparent Conductive Coatings

II-VI  is Pleased to Announce Transparent Conductive Oxide Coatings (TCO) for the 3-5 micron Region.
II-VI internal research and development efforts have result-ed in a pair of TCO coating designs that combine anti-reflection performance with elec-trical conductivity.

  • Conventional ITO—provides mid to low sheet resistance values in the visible and near IR region.
  • II-VI TCO—provides mid level sheet resistance values in the 3-5 micron region

Example curves for transmission vs. wavelength are shown on the following page for samples at normal incidence, second surface uncoated. There is a marked improvement in transmission for the LWOS TCO at 3-5μm compared to conventional ITO coating with the same conductivity.

II-VI is able to prove design variations of this coating to meet custom applications as well.

Quality Standards
These coatings will meet the quality requirements if MIL-C-675, MIL-STD-810, MIL-M-13508, MIL-F-48616, and MIL-C-48496 where applicable

Environmental Performance
Coatings are produced to meet the following test criteria:

Test
Adhesion
Abrasion 
Humidity 
Salt Fog 
Method
Cellulose tape test
Cheesecloth test
24 hours at 120F, 95-100% RH
24 hours per MIL-PRF-13830

Transmission performance of the window will be improved and can be optimized for specific wavebands by AR coating the second surface.
