Simulate windows with 3DOptix

Optical windows are essential components in optical systems, serving as transparent barriers that allow light to pass while protecting sensitive components from environmental factors. With the integration of advanced optical simulation capabilities like 3DOptix, engineers, and researchers can now accurately model and analyze the performance of all optical windows available in the catalog. This empowers them to thoroughly evaluate and optimize optical designs before implementation. Our catalog offers a diverse range of optical windows, including flat windows fabricated from various substrate materials such as N-BK7, UV fused silica (UVFS), sapphire, calcium fluoride, magnesium fluoride, potassium bromide, Infrasil, zinc selenide, silicon, germanium, barium fluoride, or polycrystalline CVD diamond. These windows provide excellent optical transmission characteristics across a wide spectral range, making them ideal for demanding applications. With such comprehensive offerings and the ability to simulate each window with precision using 3DOptix, our optical solutions provide researchers and engineers with the tools they need to innovate and excel in their endeavors.
