METHOD OF FORMING LIGHT-ABSORBING COATING Russian patent published in 2015 - IPC B44C1/22 

Abstract RU 2566905 C1

FIELD: chemistry.

SUBSTANCE: method includes preliminary chemical treatment of the initial surface of a component, electroplating with a nickel-phosphorus film and subsequent oxidation thereof in acidic solutions. The method enables to obtain a light-absorbing coating with a reflection coefficient of not more than 0.5% in a spectral wavelength range of 250-2000 nm and not more than 0.8% in the 2000-2500 nm range.

EFFECT: improved output characteristics of optical systems.
