METHOD OF FORMING COATINGS ON PARTS OF ASSEMBLIES OF OPTICAL DEVICES Russian patent published in 2025 - IPC C23C18/32 C23C22/05 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of forming coatings on parts of structural units of devices having an optical channel, and can be used in making optoelectronic equipment, including aerospace equipment and telescopes. Method of forming coatings on parts of units of optical devices comprising an optical path made of aluminium alloy, consists in fact that on entire surface of part is first applied chemically conductive adhesive coating Chem.Ox.e., then the surface of the part that is not included in the optical path is protected by a chemically resistant film, and on the working surfaces of the part, which are structural elements of the optical path, a light-absorbing nickel-phosphorus coating is applied by galvanic or autocatalytic method, after which the chemical-resistant film is removed, wherein the chemical-resistant film used is a foam tape or a galvanic tape, and a typical unit of an optical device can be a lens hood or a lens.

EFFECT: invention enables to produce structural units of optical devices such as lens hoods, lenses having high electroconductivity and super-absorbing properties of the working surface.
