Abstract
An optical construction includes a lens film and a mask layer. The lens film includes an outermost structured first major surface and an opposing outermost substantially planar second major surface. The first major surface includes a plurality of microlenses arranged along orthogonal first and second directions. The mask layer is disposed on the second major surface of the lens film and includes a first layer including a first metal, a second layer including a second metal and a third layer disposed between the first and second layers. For substantially normally incident light, each of the first and second layers has an optical reflectance of greater than about 5%, the third layer has an optical transmittance of greater than about 70%, and the mask layer has an optical reflectance of less than about 20%. The mask layer defines a plurality of through openings aligned to the microlenses in a one-to-one correspondence.
