30 mm Dia. AR Coated Sapphire Protective Flat Window for NIR II 750-1550nm
This 30 mm diameter Sapphire Protective Flat Window, with a thickness of 1 mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550 nanometers. The window is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its valid weblink status.
The window is made from high-quality Sapphire (Al2O3), a material known for its excellent optical properties, durability, and resistance to scratching and environmental damage. This makes it an ideal choice for applications that require a clear, protective window in harsh conditions.
The window features Anti-Reflective (AR) coatings on both the front and back surfaces. These coatings are designed according to Edmund Optics' NIR II standard curve, which provides optimal performance in the specified wavelength range. The AR coatings reduce surface reflections, thereby improving transmission and enhancing the overall performance of the window.
The window's geometry is that of a flat window, with a base shape of a circle. This shape ensures a consistent, uniform optical path and is less susceptible to distortion compared to other window shapes.
