This Small Business Innovation Research Phase I project will establish the feasibility to manufacture ultralarge thin sheets of ultraviolet (UV) polarizer films possessing excellent resistance to high operating temperatures and high-intensity UV radiation. Although polarization of high-intensity UV light is a key component of several important industrial processes, currently available polarizing systems do not meet industrial requirements. Reveo's inorganic films will be manufactured in large thin sheets at low cost. These films will operate at wavelengths as short as 110 nm, far shorter than standard polarizer films, and with adjustable bandwidth.The technology may even enable polarization in the currently inaccessible far UV (85 - 125nm) and extreme UV (50 - 90 nm) spectral ranges. The films are based on Reveo's newlyinvented polarizer fabrication technology that involves stacking of nano-structured layersobtained by oblique vacuum deposition. Previous research performed at Reveo has already demonstrated the viability of a similar technology in the visible region. The superior material properties, achieved through understanding and control of the film nanostructure, will ensure that the proposed UV polarizers find immediate and wide applications in material processing, chemical and pharmaceutical synthesis, and microlithography. As the first low-cost large-sheet polarizers with high efficiency, high damage threshold and high operating temperature, Reveo's inorganic UV polarizer films will be absolutely unique and find wide commercial application. The major markets for UV sheet polarizers are currently the liquid crystal display and optical components industries, but in future Reveo's UV polarizers could be the key enabling technology for low-cost chiral drug development, a huge and rapidly expanding market.

这个小型企业创新研究第一阶段项目将确定制造具有优异耐高温和高强度紫外线辐射能力的超薄紫外线（UV）偏光片的可行性。虽然高强度紫外线的偏振是几个重要工业过程的关键组成部分，但目前可用的偏振系统不能满足工业要求。revo的无机薄膜将以低成本制成大薄片。这些薄膜的工作波长短至110纳米，远短于标准偏光片，并且带宽可调。该技术甚至可以实现目前无法实现的远紫外（85 - 125nm）和极紫外（50 - 90nm）光谱范围的偏振。这些薄膜是基于revo新发明的偏振片制造技术，该技术涉及通过倾斜真空沉积获得的纳米结构层的堆叠。以前在revo进行的研究已经证明了类似技术在可见光区域的可行性。通过对薄膜纳米结构的理解和控制，实现了优越的材料性能，这将确保所提出的UV偏振器在材料加工、化学和药物合成以及微光刻等领域得到直接和广泛的应用。作为第一款具有高效率、高损伤阈值和高工作温度的低成本大片偏光片，revo的无机UV偏光片绝对是独一无二的，并将获得广泛的商业应用。目前，UV片偏振器的主要市场是液晶显示和光学元件行业，但在未来，revo的UV偏振器可能成为低成本手性药物开发的关键技术，这是一个巨大且迅速扩大的市场。
