AR Coated Zinc Sulphide Domes
Zinc Sulphide is used for missile windows due to its broadband optical transparency. HHV has in-house facilities to fabricate ZnS domes. These domes are coated with a high durability anti-reflection coating suitable for the LWIR and MWIR regions with transmittance of more than 92%. The coatings are corrosion resistant, have excellent adhesion and coated with a gold band to ensure a resistance of less than 12Ω.
