    Abstract: An optical ferrule for transmitting and propagating light having a predetermined wavelength includes a polymeric ferrule body having a fiber alignment feature for receiving an optical fiber, a redirecting side for redirecting light, and an output side window for exiting light therethrough. A multilayer anti-reflection film is disposed on the output side window and includes at least two first layers including titanium oxide and at least two second layers including silicon dioxide. At least one of the two first layers is thinner than an optimum thickness that would minimize reflection at the predetermined wavelength. Heating the optical ferrule at a temperature of about 85 degrees centigrade for at least five hours results in no, or very little, damage to the multilayer anti-reflection film.

    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.
