11-898 15 mm Dia. UVFS Round Protective Flat Window; t=2 mm NIR II 750-1550nm
The 11-898 is a circular, flat window with a diameter of 15 mm and a thickness of 2 mm. This window is made from UVFS material, specifically UVFS Mal-1965, which is known for its excellent optical properties. The window is designed to provide protection while allowing the transmission of light in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, making it ideal for applications in this range.
The window features a coating on both the front and back surfaces, specifically the EDM NIR-II STD curve coating. This coating is designed to enhance the window's performance in the NIR spectrum, providing improved transmission and reduced reflection. The coating is standard across all windows of this type, ensuring consistent performance and reliability.
The window is shaped as a thin lens, which is a type of lens with a very small thickness compared to its diameter. This shape allows the window to provide excellent optical performance while minimizing its physical size and weight. The window is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase directly from their website.
