Abstract: An optical construction includes a lens film having opposing first and second major surfaces. The first major surface includes a plurality of microlenses arranged along orthogonal directions. An optically opaque mask layer including a UV-cured polymer material is disposed on the second major surface of the lens film and defines a plurality of laser-ablated through openings therein. The openings are aligned to the microlenses in a one-to-one correspondence. For a substantially collimated light incident on the first major surface along an incident direction, an optical transmittance of the optical construction as a function of a transmitted angle includes a first transmitted peak having a first transmittance T1 at a first transmitted angle within about 10 degrees of the incident direction, and a second transmitted peak having a second transmittance T2 at a second transmitted angle between about 30 to 60 degrees of the incident direction, wherein T2/T1 ≥ 0.01.

Abstract: An optical element including an array of microlenses, a pinhole mask, and a wavelength selective filter is described. The pinhole mask includes an array of pinholes with each pinhole in the array of pinholes aligned with a microlens in the first array of microlenses. The wavelength selective filter is adapted to transmit a first light ray having a first wavelength and transmitted from a first microlens in the array of microlenses through a first pinhole in the array of pinholes aligned with the first microlens, and to attenuate a second light ray having the first wavelength and transmitted from the first microlens through a second pinhole in the array of pinholes aligned with a second microlens in the first array of microlenses adjacent to the first microlens.

Abstract: An optical system includes a lens layer having a first major surface including first and second microlenses and a first light absorbing layer. The light absorbing layer defines first and second through openings with a one-to-one correspondence between the first and second microlenses and respective first and second through openings. Each pair of first microlens and first through opening centered on a first optical axis makes a first angle with a normal to the first light absorbing layer. Each pair of second microlens and second through opening centered on a second optical axis makes a second angle, different than the first angle, with the normal to the first light absorbing layer. A light source emits light incident on the first major surface side. The emitted light includes first and second light beams carrying respective first and second information and propagating substantially parallel to the first and second optical axes, respectively.

Abstract: An optical construction includes a lens film having outermost first and second major surfaces. The first major surface includes a plurality of microlenses. A multilayer mask having an average thickness of less than about 0.5 times an average focal length of the microlenses and an optical density of greater than about 2 is disposed on the second major surface. The multilayer mask includes polymeric first and second mask layers where each of the first and second mask layers has an optical density of greater than about 0.3. The multilayer mask defines a plurality of laser-ablated through openings therein that are aligned to the microlenses in a one-to-one correspondence. An optical transmittance of the optical construction as a function of the incident angle has a transmitted peak having a peak transmittance T1 and a corresponding full width at 20 percent of maximum W1, where T1/W1 ≥ 2.4%/degree.

Abstract: An optical element includes a porous layer with a network of a plurality of interconnected voids. The porous layer is optically diffusive to at least one wavelength of light when the network of interconnected voids is substantially free of fluid. The porous layer of the optical element undergoes a detectable optical change upon fluid ingress into the network or egress from the network of interconnected voids.
