A selectively absorptive, mulitlayer wire-grid polarizer for polarizing incident light includes a stack of thin film layers disposed over a substrate, including a wire-grid array of elongated metal elements having a period less than half the wavelength of the light One of the layers can include a thin film layer with a refractive index greater than a refractive index of the substrate One of the thin film layers can include a dielectric array of non-metal elements One of the layers includes a material that is optically absorptive to the incident light

Selectively absorptive wire-grid polarizer

An inorganic, dielectric grid polarizer device includes a stack of film layers disposed over a substrate. Each film layer is formed of a material that is both inorganic and dielectric. Adjacent film layers each have different refractive indices. At least one of the film layers is discontinuous to form a form-birefringent layer with an array of parallel ribs having a period less than 400 nm. Another layer, different than the form-birefringent layer, is formed of an optically absorptive material for the ultra-violet spectrum.

Durable, inorganic, absorptive, ultra-violet, grid polarizer

A wire-grid polarizer includes a wire-grid layer disposed over a substrate. A plurality of contiguous dielectric-grid layers are contiguous with one another and disposed directly on top of the wire-grid layer. The plurality of contiguous dielectric-grid layers includes different materials with different indices of refraction. The array of dielectric material elements and the array of metal elements are oriented substantially parallel with one another, and the arrays having substantially equal periods.

There is provided an optical modeling apparatus that forms a model of a desired shape by sequentially forming hardened layers by irradiating a light-curable resin with light. The apparatus includes a first light source that emits a light beam for plotting on the resin, a scanning device that scans the light beam from the first light source over the resin, a second light source that emits light that irradiates one fixed region of the resin at a time, and a spatial light modulator that spatially modulates the light from the second light source to blanket-expose a specified region of the resin. The light beam from the scanning device and the light from the spatial light modulator form each hardened layer.

A polarized light source for a display system includes an optical system to image light from a light source onto a display along a first optical path, a reflective polarizer to receive the light from the optical system along a first optical path, direct light of a first polarization of the display, and reflect light of a second polarization along a second optical path separate from the first optical path toward the optical system, a mirror in the second optical path to receive light having the second polarization from the reflective polarizer, and reflect it back to the reflective polarizer, and a polarization conversion system in the second optical path between the reflective polarizer and the mirror to convert the polarization of the reflected light of the second polarization to the first polarization.
