UV polarizers

UV polarizers are widely used in various fields of science and technology, for example, when studying the distribution of mechanical stresses in transparent objects using polarized light, when studying the structure of organic substances, in saccharimetry, crystal optics, astronomy, and photography. Alpine Research Optics polarizers UVD260 and UVD240, manufactured using nanowire technology, compare favorably with the traditional Glan-Taylor and Glan-Thompson prism polarizers used in spectroscopy. Thanks to the advantages and design features, it was possible to achieve high efficiency in a wide spectral range from UV to IR.The operating wavelength range of our polarizers starts in the far UV region from 240 nm and ends in the near-infrared range with a cutoff wavelength of 3.3 μm. For the production of the Proflux series polarizers, ARO uses nanowire technology, which today makes it possible to produce polarizers with the shortest structure period. The polarizer consists of thin (several tens of nanometers thick) aluminum strips deposited parallel to each other on a quartz plate (Fig. 1). Unpolarized light, falling on such a polarizer, is divided into two components: one, in which the oscillations of the light vector are directed perpendicular to the plane of incidence, passes through the plate, and the second, with oscillations in the plane of incidence, is reflected as from a metal mirror.

Precision Optics

Since its founding, ARO has been improving optical machines and technologies for the processing of precision optics. Each optical part has its characteristics and requires an individual approach during its manufacture. A wide range of processed materials, geometric shapes, and accuracy characteristics imply the presence of a large and technological machine tool park. Today Alpine Research Optics offers its customers the widest range of technologies for the processing and control of precision optics.

Alpine Research Optics technologies

ARO has long occupied one of the leading positions both among manufacturers of optical components and optical crystals for the visible and IR spectral range. The company manufactures both standard products from the catalog and custom-made optical components for a wide range of wavelengths from 193 nm to 50 μm, from various optical crystals and glasses, with and without coatings, for laser, medical, aviation, and special equipment. These are infrared optics, optics of the visible and ultraviolet range: windows, plates, optical fairings (caps), light filters, lenses, prisms, wedges, mirrors, laser optics made of various optical materials, including crystals grown on their growth attitudes.Alpine research optics successfully produces optical crystals: zinc selenide (CVD-ZnSe), zinc sulfide (CVD-ZnS), sapphire Al2O3 (leucosapphire), calcium fluoride CaF2, barium fluoride BaF2, magnesium fluoride MgF2, and lithium fluoride in the form of lithium blanks of windows), also grows blanks of fairings (caps), namely: domes — fairings (hemispheres and hyperhemispheres) made of zinc selenide (CVD-ZnSe), zinc sulfide (CVD-ZnS) and sapphire Al2O3 (leucosapphire). Polishing of CVD-ZnSe, CVD-ZnS, and sapphire fairings and application of broadband antireflection coatings to the fairing caps has long been developed at the enterprise.
