Patent ID: 8198120

Claim:
A method comprising: a) providing a first layer of material having a capability of multiple wavelength band radiation transmission, the first layer material is chosen from zinc sulfide, water clear zinc sulfide and zinc selenide; b) depositing an electrically conductive and selectively passivated pattern on the first layer of material having the capability of multiple wavelength band radiation transmission, the electrically conductive and selectively passivated pattern comprises one or more metal or metal alloy layers; c) activating the electrically conductive and selectively passivated pattern and the first layer of material with hydrogen sulfide; and d) depositing a second layer of material having a capability of multiple wavelength band radiation transmission on the electrically conductive and selectively passivated pattern opposite the first layer to form an article having optical multi-aperture operation, the second layer of material is chosen from zinc sulfide, water clear zinc sulfide and zinc selenide.
