This 11-891 optical window, sourced from Edmund Optics, is a 25 mm diameter, 1 mm thick component made from UVFS material with a Mal-1965 index. It is designed for use in the near-infrared spectrum, specifically between 600 and 1050 nanometers, making it suitable for a wide range of optical applications.
The window features a standard NIR-I coating on both the front and back surfaces, which is Edmund Optics' proprietary coating. This coating is designed to enhance the performance of the window in the near-infrared region, providing improved transmission and reducing unwanted reflections.
The window's geometry is that of a thin lens, with a flat surface on both sides. This design ensures minimal distortion and maintains the integrity of the light passing through it. The window is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
