A package of a heat-bent polarizing sheet for producing an injection-molded polarizing lens and an injection-molded polarizing lens that uses said sheet is provided. The heat-bent polarizing sheet is cumulatively packaged by a non-adhesive isolation film so as to withstand moisture and then stored or transported and can be used in injection molding without performing preliminary drying as a pretreatment of injection molding and without substantial protective-film removal work.

The disclosure relates to an optical element, including: a substrate, a first coating, which is disposed on a first side of the substrate and is configured for reflecting radiation having a used wavelength (λ.sub.EUV) in the EUV wavelength range, and a second coating, which is disposed on a second side of the substrate, for influencing heating radiation that is incident on the second side of the substrate. The disclosure also relates to an optical arrangement having at least one such optical element.

Each wire of a wire grid polarizer (WGP) can include the following layers moving outwards from the substrate: a high-index-layer, a low-index-layer, and a reflective-layer. Each wire can have a distal-end, farthest from the substrate, with a convex shape. These layers and the convex shape can be combined for a more stable and improved Rs.

A polarizer arrangement for polarizing a laser beam includes: multiple plate-shaped optical elements which are arranged in a beam path of the laser beam and each of which includes a beam entry surface for the laser beam and a beam exit surface for the laser beam, in which the beam entry surface of a respective plate-shaped optical element is oriented at the Brewster angle relative to the laser beam. The beam entry surfaces and the beam exit surfaces of the plate-shaped optical elements are in each case oriented at least at one wedge angle relative to one another. An EUV radiation generating device may include such a polarizer arrangement.

Provided is a circularly polarizing plate capable of improving a reflection color by using a retardation film with flat dispersion characteristics, and an OLED device comprising the circularly polarizing plate.

The present invention is to provide an appropriate configuration of a VUV polarizer that can be used for such a process as photo-alignment. The VUV polarizer can polarize VUV light not more than 200 nm in wavelength, and has a substrate transparent to the VUV light and a grid on the substrate. The grid is formed of a lot of linear parts in parallel and structured with no filler between the linear parts. A material of each linear part is an oxide of a Group 3 element or Group 4 element, and makes PE not less than 0.2 under an optical constant combination making PE maximum in the VUV range, where PE=T.sup.2×log.sub.10(ER), T is the transmittance of the grid, and ER is the extinction ratio of the grid. A workpiece is subjected to a photo-alignment processing by irradiation of VUV polarized light emitting from the VUV polarizer.

The invention disclosed herein generally relates to wideband resonant polarizers that require extremely small amounts of matter in their embodiments. These polarizers can be made with dielectric materials such that light and other electromagnetic waves interacting with them suffer essentially no absorptive loss. This new class of polarizers is fashioned with dielectric or semiconductor nano/microwire grids that are mostly empty space if surrounded by air or vacuum. It is fundamentally and practically extremely significant that the wideband spectral expressions presented herein can be generated in these minimal systems. These ultra-sparse polarizers are useful in various spectral regions for numerous useful applications.

A high refractive index, polarized spectacle lens and a process for the production of the lens are provided. The lens includes a high refractive index lens substrate and a multi-layer, polarized film. The multi-layer, polarized film, in turn, includes at least one transparent support layer and at least two adhesion layers, wherein at least one of the adhesion layers is a polarized adhesion layer.

Methods for fabricating thin, high-aspect-ratio Ge nanostructures from high-quality, single-crystalline Ge substrates are provided. Also provided are grating structures made using the methods. The methods utilize a thin layer of graphene between a surface of a Ge substrate, and an overlying resist layer. The graphene passivates the surface, preventing the formation of water-soluble native Ge oxides that can result in the lift-off of the resist during the development of the resist.
