METHOD OF MAKING COMPOSITE LENS PANEL FOR NANO-HETEROSTRUCTURE BASED CONCENTRATOR PHOTOELECTRIC TRANSDUCERS Russian patent published in 2011 - IPC G02B3/08 B29D11/00 

FIELD: physics.

SUBSTANCE: method involves making negative matrices of Fresnel lenses with a square aperture from metallic workpieces coated with a layer of electrolytic copper with thickness of 0.5-3.0 mm via diamond turning of the copper coating. A 0.02-0.1 mcm thick chromium layer is deposited on the working surface of the inverse matrices and the matrices are joined by their ends into an assembly which is in form of a panel. An intermediate positive copy of the panel of Fresnel lenses is made via cathodic electrodeposition of nickel onto the working surface of the assembly. A 0.02-0.1 mcm thick chromium layer is deposited on the working surface of the intermediate positive copy of the panel. A negative copy of the panel is made through cathodic electrodeposition of nickel onto the working surface of the intermediate positive copy. A two-component silicon compound is poured between the working surface of the negative copy of the panel and the surface of silicate glass. The compound is polymerised at temperature defined by the relationship given in the formula of invention. The silicate glass with the composite lens panel is separated from the negative copy of the panel.

EFFECT: high quality of lens panels and low production costs owing to longer service life of the intermediate matrix.
