PROTECTIVE COATING FOR HYGROSCOPIC OPTICAL MATERIALS BASED ON LASER-PRECIPITABLE CARBON NANOTUBES FOR PURPOSES OF OPTOELECTRONICS AND MEDICAL EQUIPMENT Russian patent published in 2015 - IPC G02B1/10 B82B1/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to the field of optical nanotechnologies, optical instrument-making, rocket, space, laser optics, quantum and optical nanoelectronics, useful for display, television and medical technology. The optical coating is a thin layer (100 nm or less) coating based on carbon nanotubes with the magnitude of inhomogeneities on the nanometer level. For application of carbon nanotubes on the substrate a slot CO₂-laser is used with the laser beam controlled in power. The optical element consists of the coating based on carbon nanotubes and a hygroscopic substrate. The substrates of KBr, NaCl, KCl are used for providing functioning of this optical coating up to the middle infrared region of the spectrum. The coating is able to function in the infrared regions of the spectrum.

EFFECT: increased moisture resistance of the coating.
