An augmented reality head worn device having a a curve transparent mirror, a scanning light source defining a field of view, a holographic optical element adapted to provide pupil expansion to create an eye-box, and at least one projection system for providing high acuity at or near a center of the field of view.

An optical filter may reduce the frequency and/or severity of photophobic responses or for modulating circadian cycles by controlling light exposure to cells in the human eye in certain wavelengths, such as 480 nm and 590 nm, and a visual spectral response of the human eye. The optical filter may disrupt the isomerization of melanopsin in the human eye reducing the availability of the active isoform, whereas the attenuation of light weighted across the action potential spectrum of the active isoform attenuates the phototransduction cascade leading to photophobic responses. Embodiments of an optical filter are described. In one embodiment an optical filter may be configured to transmit less than a first amount of light in certain wavelengths, and to transmit more than a second amount of light weighted across the visual spectral response. Methods of use and methods of manufacturing optical filters are also described.

A thin-film optical device is formed on a substrate by atomic layer deposition. A mixing system provides a homogeneous gaseous mixture having a controllable ratio of first and second reactive gaseous materials. The first and second reactive gaseous materials each react with a third reactive gaseous material but do not react with each other. The homogeneous gaseous mixture is provided to a first inlet port, the third reactive gaseous material is provided to a second inlet port, and an inert gaseous material is provided to a third inlet port. The gas flows are directed through corresponding output channels of the delivery head toward the substrate. The mixing system is controlled to change the ratio of the first and second reactive gaseous materials as a function of time as the substrate is moved relative to the delivery head with an oscillating motion such that deposited layers have a varying composition.

A Coating, a system of coatings and a method to produce thin film coating, deposited by a stream of particles, produced by thermal evaporation or magnetron/ion-beam sputtering, wherein the thin film coating comprises at least 3 distinct refractive index layers, out of a single target (10) material. In the process of the coating, vapor flux or particle stream is pointed obliquely to the uncovered surface of the substrate (1), which can be rotated about an axis (12), parallel to the surface of the substrate. The substrates can also be rotated about an axis (16), co-aligned with the normal vector of the substrate, to obtain an evenly deposited coating with the desired amorphous structure. The structure of the coating is selected in a pattern, which allows the porosity in-between adjacent layers to be varied. As a consequence, achieving a reflectance of the coating of at least 90% for at least one frequency radiation or polarization component.

Provided is an optical filter including first and second reflection layers separated from each other, a dielectric region interposed between the first and second reflection layers and in which two materials of which refractive indexes are different are alternately disposed, and a buffer layer disposed between the dielectric region and at least one of the first and second reflection layers, wherein there are at least two filter regions in which relative volume ratios of the two materials alternately disposed are different.

Method for producing an optical layer system that includes a multiplicity of layers arranged on a substrate, where part of the layers has a high refractive index n.sub.H, another part has a low refractive index n.sub.L and a further part has a middle refractive index n.sub.M, where n.sub.H>n.sub.Mn.sub.L and the layers having different refractive indices have an alternating stacked arrangement. The layers of the optical layer system are deposited onto a substrate by a selected coating method from an identical material which is hydrogenated amorphous silicon (a-Si:H) or hydrogenated germanium (Ge:H), where a refractive index and an extinction coefficient of each layer of the multiplicity of layers of the layer system are adjusted by a regulation of process parameters of the selected coating method.
