摘要： Tags are made from optical films to provide a pattern that is inconspicuous to ordinary observers, but that is detectable by a camera or other imaging device. The pattern is provided by first and second portions of a patterned layer, the first portions selectively filtering at least a portion of blue visible light from other visible light wavelengths. Filtering in the portion of the blue region helps make the pattern inconspicuous. The tags may also include an indicia layer configured to mark a location of the pattern, and a contrast enhancing layer disposed behind the patterned layer and configured to enhance a contrast of the pattern. In some cases, the first portions of the patterned layer may filter optical wavelengths other than blue, such as near-infrared light. The pattern may comprise machine-readable information, e.g., a linear bar code or a 2-D bar code. Associated methods and systems are also disclosed.

摘要： A multilayer optical film including a first layer having an index of refraction n1 at a wavelength λ in a range from about 580 nm to about 650 nm, and a second layer having an index of refraction n2 at λ is described. The first and second layers define an interface therebetween comprising a two-dimensional grating. The grating may have an average height H such that |n1−n2|*H is in a range from 0.24 micrometers to 0.3 micrometers. Optical systems including the multilayer optical film are described. A subpixel in a display surface of the optical system may be diffracted into a zero diffraction order and a plurality of first diffraction orders where the intensities of the zero and first diffraction orders are with 10% of each other at λ. The optical system may have a modulation transfer function greater than 0.4 at 10 line pairs per millimeter.

摘要： Microstructured films such as brightness enhancing films. The microstructured film has a polymerized structure comprising the reaction product of the polymerizable resin composition (e.g. having a refractive index of at least 1.58). The cured nanocomposite (e.g. structure) can exhibit improved crack resistance. In some embodiments, the flexibility is expressed in terms of a cylindrical mandrel bend test property (e.g. a mandrel size to failure of less than 6 mm or a mandrel size to failure according to the equation D=1000(T/0.025−T) wherein T is the thickness in millimeters of a (e.g. preformed base layer). In other embodiments, the flexibility is expressed in terms of a tensile and elongation property (e.g. a tensile strength at break of at least 25 MPa and an elongation at break of at least 1.75%).

摘要： A backlight for an image forming device includes spaced-apart front and back optical reflectors defining an optical cavity therebetween, and at least one light source for emitting light into the optical cavity. The front optical reflector may be disposed between the image forming device and the back optical reflector. For substantially normally incident light and for nonoverlapping first and second wavelength ranges, the front optical reflector may transmit at least 70% of light for each wavelength in the first wavelength range, and may reflect at least 70% of light for each wavelength in the second wavelength range. The back optical reflector may reflect at least 70% of light for each wavelength in the first wavelength range, and may transmit at least 70% of light for each wavelength in the second wavelength range. The emitted light may have at least one wavelength in the first wavelength range and at least one wavelength in the second wavelength range.

摘要： A backlight (100) for an image forming device (70) includes spaced-apart front and back optical reflectors (20, 10) defining an optical cavity (18) therebetween, and at least one light source (15) for emitting light into the optical cavity. The front optical reflector (20) is disposed between the image forming device and the back optical reflector (10). For substantially normally incident light and for non-overlapping first (e.g. visible light) and second (e.g. infrared) wavelength ranges, the front optical reflector (20) may transmit (80c) at least 70% of light (80a) for each wavelength in the first wavelength range, and may reflect (90b) at least 70% of light (90a) for each wavelength in the second wavelength range. The back optical reflector (10) may reflect (80b) at least 70% of light for each wavelength in the first wavelength range, and may transmit (90c) at least 70% of light (90b) for each wavelength in the second wavelength range. The light (80a, 90a) emitted by the at least one light source (15) has at least one wavelength in the first wavelength range and at least one wavelength in the second wavelength range.
