The 65-870 is a 5 mm diameter, 1 mm thick flat window made from UVFS material with a Mal-1965 index, sourced from Edmund Optics. This window is designed to protect optical systems and is suitable for use in a wide range of applications due to its UV-AR coating, which covers the wavelength range of 250-425 nm on both the front and back surfaces.
The UVFS material, or Ultraviolet Fused Silica, is a high-purity fused silica that offers excellent transmission in the deep UV region. It is known for its high resistance to thermal shock and devitrification, making it an ideal choice for applications that require a durable and reliable window.
The window features a standard UV coating, which is designed to provide excellent protection against UV radiation while maintaining high transmission in the visible and near-infrared regions. This coating is deposited on both the front and back surfaces of the window, ensuring optimal protection for your optical system.
The window's thin lens shape allows for easy integration into various optical systems. With its high-quality UVFS material, standard UV coating, and robust design, the 65-870 is a reliable and versatile protective window for your optical needs.
