Abstract: A technique of determining the presence of a species in a sample may include passing light through an optical filter. In an example, the optical filter may include a spatially variant microreplicated layer optically coupled to a wavelength selective filter. The wavelength selective filter may have a light incidence angle-dependent optical band. The spatially variant microreplicated layer may be configured to transmit light to a first optical region of the wavelength selective filter at a first predetermined incidence angle and to a second optical region of the wavelength selective filter at a second predetermined incidence angle.

Abstract: An example optical filter may include an angle blocking layer having a first angular light blocking range θAL relative to a normal axis, and an interference filter adjacent the angle blocking layer having a second angular light blocking range θIF relative to the normal axis. θIF and θAL at least partially overlap. The example optical filter has a predetermined light transmission zone comprising angles from 0° to a maximum light transmission angle θTmax relative to a normal axis of the major surface. The example optical filter has a predetermined angular light blocking zone θB, a union of θIF and θAL. An example optical filter may include an interference filter having an incidence angle-dependent reflection band and an absorbing layer having an absorption band. The incidence angle-dependent reflection band and the absorption band may overlap at at least one wavelength at at least one angle of incidence.

Abstract: An optical stack including an oriented polymeric multilayer optical film and a non-birefringent optical filter is described. The oriented polymeric multilayer optical film has a first reflection band with a first band edge and the non-birefringent optical filter has a first blocking band. In some cases, the first blocking band contains the first band edge and the first blocking band provides a reduction in variation of a band edge of an overall blocking band of the optical stack.

Abstract: The inventors of the present application developed novel optically active materials, methods, and articles. One embodiment of the present application is an optically active article, comprising: an infrared-reflecting material positioned adjacent to an optically active substrate such that the infrared-reflecting material forms a pattern that can be read by an infrared sensor when the optically active substrate is illuminated by an infrared light source.Another embodiment of the present application relates to a method of manufacturing an optically active article, comprising: obtaining an optically active sheeting; and positioning an infrared-reflecting material on the optically active sheeting to form a pattern. The optically active article may be, for example, a license plate.

Abstract: A transparent display booth for displaying products and providing product-related information. The display booth includes a bottom panel, a back panel, a transparent front plate opposite the back panel, and a transparent display device located co-extensive with the front plate. The bottom and back panels have reflective inner surfaces. The transparent display device can electronically display product-related information, and products located in an interior of the display booth are viewable through the transparent display device to showcase the products and offer them for sale. Multiple transparent display booths can be combined to form a networked retail system.

Abstract: A light control film is disclosed that includes a plurality of spaced apart first regions. Each first region has a substantially low transmission in one or two of a first wavelength range from about 300 nm to about 400 nm, a second wavelength range from about 400 nm to about 700 nm, and a third wavelength range from about 700 nm to about 1200 nm, and a substantially high transmission in the remaining wavelength ranges. The light control film has a viewing angle of less than about 70 degrees along a predetermined first direction.

Abstract: A multilayer optical film (130) has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film Heating elements (122) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered regions of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered regions to pattern the film The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g. reduce) the birefringence of the birefringent microlayers disposed near the outer exposed surface in the altered regions, while providing sufficient mechanical support to avoid substantial layer distortion of the microlayers near the outer exposed surface in the altered regions.
