Lightweight mirrors with reflectance over 98% in IR spectrum
AR Coatings for IR, Visible and UV Transmissions
Valley Design offers a variety of anti-reflection (AR) coatings. These coatings can improve optical performance, but it is important to use these coatings inside the designated wavelength, or system performance can be impeded. The entire spectral range of the optical system needs to be taken into consideration when choosing the appropriate wavelength for AR coating of optical components.
Anti-reflection (AR) coatings are used to improve the efficiency of an optic by increasing transmission, enhancing contrast and eliminating “ghost” images, which are reflections that travel backwards into the system. When specifying AR coating requirements, specific wavelengths within the IR, VIS and UV ranges must be designated.
Valley offers these AR coatings, and can also supply the substrates for coating. Substrates and wafers of all materials are available from Valley Design, many of which are in stock. From Fused Silica, Glass of all types, Ceramics such as 96% and 99.6% Alumina and Aluminum Nitride, Silicon, Sapphire and more, we can fabricate any standard or custom size and thickness. Tight tolerances and super polished surface finishes are also available.
