Abstract: An optical construction includes a lens film having an outermost structured first major surface and an opposing outermost substantially planar second major surface. The first major surface includes a plurality of microlenses. A radiation cured optically opaque mask layer is disposed on the second major surface of the lens film. The mask layer has an average thickness of less than about 10 microns and defines a plurality of laser-ablated through openings therein. The through openings are aligned to the microlenses in a one-to-one correspondence, such that for a light incident on the structured first major surface along an incident direction forming an incident angle with the second major surface, an optical transmittance of the optical construction as a function of a transmitted angle includes a first transmitted peak having a first peak transmittance T1≥40%. The first transmitted peak can be within about 10 degrees of the incident angle.

Abstract: Example systems may include one or both of a light emitter and a light receiver, and an optical filter. The optical filter may include a wavelength selective scattering layer configured to scatter visible light. The optical filter may include a wavelength selective reflecting layer having a predetermined transmission band configured to compensate for a color deviation. The optical filter may include a broadband reflecting layer having a predetermined reflection band configured to compensate for a color deviation. The optical filter may include a low-index layer configured to reduce a color deviation in light emitted by the light emitter or received by the light receiver. The wavelength selective scattering layer may include nanoparticles dispersed in a binder, wherein the ratio of the nanoparticles to the binder by weight is at least 50%. Example articles may include example optical filters.

Abstract: In general, techniques are described for a personal protective equipment (PPE) management system (PPEMS) that uses images of optical patterns embodied on articles of personal protective equipment (PPEs) to identify safety conditions that correspond to usage of the PPEs. In one example, an article of personal protective equipment (PPE) includes a first optical pattern embodied on a surface of the article of PPE; a second optical pattern embodied on the surface of the article of PPE, wherein a spatial relation between the first optical pattern and the second optical pattern is indicative of an operational status of the article of PPE.
