39-259 38.1 mm Dia. AR Coated Sapphire Protective Flat Window; t=1 mm NIR I 600-1050nm

The 39-259 is a high-quality protective flat window, boasting a large 38.1 mm diameter and a thickness of 1 mm. This window is made from sapphire, a material with the chemical formula al2o3, and is sourced from Edmund Optics. The sapphire material is known for its excellent hardness, making it highly resistant to scratches and abrasions, ensuring longevity and durability.

The window features an Anti-Reflective (AR) coating on both the front and back surfaces, specifically designed for the Near-Infrared (NIR) I region, which covers the wavelength range of 600-1050nm. This coating significantly reduces reflective losses, thereby enhancing transmission efficiency. The coating is standard, following the EDM NIR-I curve, ensuring consistent performance and reliability.

The window's geometry is that of a thin lens, making it suitable for a wide range of optical applications.
