The 11-895 is a 10 mm diameter flat window, boasting a thickness of 1.25 mm, designed for use in the near-infrared (NIR) spectrum. This window is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The window is made from UVFS material, specifically UVFS Mal-1965, which is known for its excellent transmission properties in the NIR range. The window's geometry is circular, making it suitable for a wide range of applications where a flat, circular window is required.
The 11-895 is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is specifically designed to enhance the window's performance in the NIR-II region, which spans from 750 to 1550 nanometers. This coating ensures high transmission rates and reduces unwanted reflections, making it ideal for use in applications such as biomedical imaging, spectroscopy, and optical communication.
The window is shaped as a thin lens, which can provide some focusing capabilities, depending on the application. However, its primary function is to protect optical elements from environmental hazards while maintaining high optical quality.
