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.

Applications
Automotive, Consumer Electronics, 3D Sensing in Biometrics, 3D Sensing in VR & AR, Human Machine Interface, In-cabin Interaction, Internet of Things, LiDAR Sensing, Conductive Coatings, OPTICAL SYSTEMS
