Optical construction including lens film and mask

An electronic device comprising:

• an optical construction comprising:
• a lens film comprising an outermost structured first major surface and an opposing outermost substantially planar second major surface, the structured first major surface comprising a plurality of microlenses;
• and
• a mask disposed adjacent to the second major surface of the lens film and comprising a polymeric layer, a nanoparticle layer, and a plurality of infrared laser-ablated openings disposed through the mask, the openings aligned to the microlenses in a one-to-one correspondence, wherein the nanoparticle layer comprises nanoparticles that are sintered together after the openings are laser ablated through the mask, and wherein the nanoparticles are visibly transparent at least from about 450 nm to about 650 nm and infrared absorbing;
• and
• an optical sensor disposed adjacent to the optical construction such that the mask is disposed between the lens film and the optical sensor.
