Zinc Sulfide WIKI
I believe I have identified the chemtrail aerosol sprayed material that was spread out all up & down my driveway on Feb. 22, 2016 – and that I also found in blobs on my neighbor’s deck/glass table top. One of the listed ‘materials’ in the Navy Manual is Zinc Sulfide.
WIKI: Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics.
Zinc sulfide is also used as an infrared optical material, transmitting from visible wavelengths to just over 12 micrometers. It can be used planar as an optical window or shaped into a lens. It is made as microcrystalline sheets by the synthesis from hydrogen sulfide gas and zinc vapour, and this is sold as FLIR-grade (Forward Looking IR), where the zinc sulfide is in a milky-yellow, opaque form.
Zinc Sulfide (along with toxic lithium, aluminum, barium, and cadmium) is listed as a material used in the ‘Electronic Warfare & Radar Systems Engineering Handbook’ issued by the Department of the Navy USA, the Naval Air Warfare Center Weapons Division. This handbook is said to be UNCLASSIFIED and “approved for public release.” (available at amazon)
The radiation emitted or reflected from the targets and backgrounds must pass through the intervening atmosphere before reaching the detection system. The radiation is absorbed and re-emitted by molecular constituents of the atmosphere and scattered into and out of the path by various aerosol components.
Figure 11 reveals the presence of atmospheric windows, i.e. regions of reduced atmospheric attenuation. IR (infrared) detection systems are designed to operate in these windows.
ELECTRO-OPTICAL COMPONENTS AND SENSORS
Windows / Domes / Lens Materials
For most applications of EO (electro-optical) systems in EW, the detection system is protected from the environment by a window or dome of optically transmissive material.
Transmission bands of representative window or lens materials are shown in Figure 14.
