Assemblies (10), devices, and methods are described herein that allow an examiner to inspect a container (12) of liquid product (14) through a bottom wall (18) of the container using a line-of-sight diversion member (28, e.g. beam splitter, mirror or prism). In some forms, the assemblies described herein can be provided with mounts and connecting arms to couple the devices to inspection booths.

Provided are a wavelength selective absorption filter containing a resin and a dye A, which has a main absorption wavelength band in the wavelength selective absorption filter at a wavelength of 400 to 450 nm, and a dye C, which has a main absorption wavelength band in the wavelength selective absorption filter at a wavelength of 560 to 600 nm, each of which has a main absorption wavelength band in a different wavelength range, as well as a polarizing plate and an organic electroluminescent display device or liquid crystal display device, which include the wavelength selective absorption filter. However, the dye A and the dye C do not have fluorescence.

A laser source assembly is provided. The laser source assembly includes a plurality of lasers, a light combining assembly and a fly-eye lens. The fly-eye lens is disposed on a light exit side of the light combining assembly, and is configured to homogenize laser beams. The fly-eye lens includes a plurality of first microlenses located on a light incident surface thereof and a plurality of second microlenses located on a light exit surface thereof. A sine value of a divergence angle of a laser beam in a fast axis direction is greater than a sine value of an aperture angle of a first microlens in a slow axis direction, and a sine value of a divergence angle of the laser beam in the slow axis direction is greater than a sine value of an aperture angle of the first microlens in the fast axis direction.

A pattern forming method comprises dispensing a curable composition onto an underlayer of a substrate; bringing the curable composition into contact with a mold; irradiating the curable composition with light to form a cured film; and separating the cured film from the mold. The proportion of the number of carbon atoms relative to the total number of atoms in the underlayer is 80% or more. The dispensing step comprises a first dispensing step of dispensing a curable composition (A1) substantially free of a fluorosurfactant onto the underlayer, and a second dispensing step of dripping a droplet of a curable composition (A2) having a fluorosurfactant concentration in components excluding a solvent of 1.1% by mass or less onto the curable composition (A1) discretely.

Provided is an imaging apparatus that captures a multispectral image having a good image quality. An imaging apparatus (1) includes an imaging optical system (10) that includes a pupil region which is split into a plurality of regions including a first pupil region and a second pupil region different from the first pupil region, and a polarization filter which polarizes light beams passing through the first pupil region and the second pupil region in directions different from each other, an imaging element (100) that includes a first pixel which receives the light beam passing through the first pupil region and a second pixel which receives the light beam passing through the second pupil region, and a signal processing unit (200) that processes signals output from the imaging element (100), and outputs at least first image data consisting of an output signal of the first pixel and second image data consisting of an output signal of the second pixel. In the imaging optical system (10), wavelengths of the light beams passing through the first pupil region and the second pupil region are different from each other, and aberration characteristics of regions corresponding to the first pupil region and the second pupil region are different from each other.

This polarized light-emitting film contains a water-soluble coumarin compound represented by formula (1) (in formula (1), A represents an optionally substituted coumarin skeleton, X represents a sulfo group or a carboxyl group, and n represents an integer of 1 to 3.) or a salt thereof.

An optical proximity sensor system to detect a distance to a target object is provided. The optical proximity sensor system includes a laser that generates an emitted optical beam at a linear polarization and an optical cavity system that includes an optical cavity defined by a distance between the laser and the target object. The target object reflects the emitted optical beam to generate a reflected optical beam. A partially reflective mirror diverts a portion of the emitted optical beam and/or the reflected optical beam. A photodetector receives the diverted optical beam and generates a proximity signal that has a frequency that is indicative of the distance to the target object based on the diverted portion of the at least one of the emitted optical beam and the reflected optical beam. A proximity processor calculates the distance to the target object based on the frequency of the proximity signal.

A polarizing plate includes a polarizing layer over a base material, an inorganic insulation layer over the polarizing layer, and a water-resistant layer over the inorganic insulation layer, where the water-resistant layer covers sidewalls of the polarizing layer and sidewalls of the inorganic insulation layer, when the base material is viewed from a top plan view.

A display device includes a display module and an anti-glare film on the display module. The anti-glare film includes a first anti-glare layer and a second anti-glare layer. The first anti-glare layer has a plurality of microstructures at an upper surface of the first anti-glare layer. A root-mean-square slope of the microstructures is more than 0 and is 0.2 or less. The second anti-glare layer is between the first anti-glare layer and the display module, and an inner haze of the second anti-glare layer is from 20% to 90%.

A waveguide illuminator includes an input waveguide, a waveguide splitter coupled to the input waveguide, and a waveguide array coupled to the waveguide splitter. The waveguide array includes an array of out-couplers out-coupling portions of the split light beam to form an array of out-coupled beam portions for illuminating a display panel. To reduce optical interference, the waveguide illuminator may have two interlaced waveguide arrays energized by two different light sources. Output polarizations of neighboring light pixels of a display illuminated with such waveguide illuminator may be orthogonal to each other. The frames to be displayed may be broken down into sequentially displayed sub-frames with interleaved pixels.
