LENS RASTER IN FORM OF TRIPLEX FOR FORMING AUTOSTEREOSCOPIC IMAGE AND METHOD OF MAKING SAME Russian patent published in 2016 - IPC B29D11/00 

FIELD: physics.

SUBSTANCE: lens raster is in the form of a set of positive lenticular lenses whose surface is placed in an immersion medium. The immersion medium is the polymer which is obtained by curing the photopolymerisable composition which contains oligourethane(meth)acrylates and/or oligomers of mono(meth)acrylate of oxyalkylene glycol, one or more mono- or di(meth)acrylic monomers and a radical photochemical polymerisation initiator, with the following ratio of components, wt %: oligourethane(meth)acrylates and/or oligomers of mono(meth)acrylate of oxyalkylene glycol 79.1-39.5, mono- or di(meth)acrylic monomers 59.5-19.7, polymerisation initiator 1-3. The immersion medium is the internal layer of the lens raster - solid polymer immersion layer - silicate glass triplex, and the refraction index of the material of the lens raster is greater than the refraction index of the polymer immersion layer by not less than 0.006.

EFFECT: easier use, improved manufacturability and optical and mechanical stability.
