5x0.2 mm Silicon Round Optical Window, DLC Coated

Product description

Silicon protective windows are designed for thermal imaging applications, providing excellent durability and performance across multiple infrared bands (0.7-1.7 μm, 3-5 μm, 8-14 μm). With a combination of anti-reflection (AR) and Diamond-Like Carbon (DLC) coatings, these windows ensure high IR transmission while protecting against harsh environments. Their optical properties make them a reliable alternative to traditional materials like germanium.
