DIFFRACTION GRATING PRINT MANUFACTURING PROCESS Russian patent published in 1994 - IPC

Abstract SU 1297624 A1

FIELD: spectral instrumentation engineering. SUBSTANCE: oligourethanacrylate of formula 1 or oligoepoxymetacrylate of formula 11 is used as oligomer in sequential coating of glass matrix of diffraction grating with mannitol. aluminium, silicon, and oligomeric composition and isobutyl benzoyl ester, as initiator. Glass substrate pre-treated with methacryloxymethyltriethoxylan is placed onto oligomeric composition and the latter is hardened with ultraviolet light, illuminating and heating conditions being selected to provide its full transformation into polymer. Manufactured print is separated from grating. EFFECT: reduced manufacturing time, improved stability of diffraction grating print to environmental conditions. 2 tbl
