Abstract: An optical assembly (200) including an encapsulated multilayer optical film (250). Methods of making and using such optical assemblies also are disclosed.

Abstract: An optical assembly including an optical element insert molded directly onto an optical stack is provided. The optical stack includes an optical film and may include a liner with the optical film being disposed between the optical element and the liner. The liner, if included, is removable from the optical film without substantial damage to the optical film. An outermost layer of the optical film may be diffusion bonded to a major surface of the optical element.

The optical film includes a protective coating having an average thickness of no more than 30 micrometers. The protective coating includes an at least partially cured composition. The composition includes 70 to 96 weight percent of urethane (meth)acrylate compound having an average (meth)acrylate functionality of 2 to 9.5, and 2 to 20 weight percent of (meth)acrylate monomer having a (meth)acrylate functionality of 1 to 2.

Abstract: A method of making an infrared-reflecting optically transparent assembly comprises: coating a curable composition onto a major surface of an optically transparent thermoplastic polymer film; at least partially curing the curable composition, which may be optionally at least partially dried, to provide a thermoformable composite film; and laminating the thermoformable composite film to an infrared-reflecting multilayer optical film to provide the infrared-reflecting optically transparent assembly. The curable composition comprises urethane (meth)acrylate compound, (meth)acrylate monomer, and silicone (meth)acrylate. The infrared-reflecting optically transparent assembly and methods of including it in an infrared-reflecting lens assembly are also disclosed.

Abstract: A curved optical film generally lying in a base plane and having a thickness of less than 500 microns, and an average optical absorption of less than 70% for unpolarized normally incident light in a predetermined wavelength range is described. A first cross-section of the optical film in a first plane perpendicular to the base plane has an actual first length AL1 a projected first length PL1, and a first stretch ratio S1 of (AL1?PL1)/PL1. A second cross-section of the optical film in a second plane perpendicular to the first and base planes has an actual second length AL2, a projected second length PL2, and a second stretch ratio S2 of (AL2?PL2)/P2. The optical film may have a maximum thickness variation of less than 20% along each of the first and second cross-sections, S1 may be at least 0.1, and S2 may be at least 0.01 and less than 0.8S1.
