83-471 20 mm Dia. N-BK7 Precision Protective Flat Window; t=3 mm NIR I 600-1050nm
The 83-471 is a 20 mm diameter, 3 mm thick N-BK7 precision protective flat window, designed for use in the near-infrared (NIR) spectrum, specifically between 600 and 1050 nanometers. This window is sourced from Edmund Optics, a leading provider of optical components.
The window is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This makes it an ideal choice for applications that require high precision and stability over a wide temperature range.
The window features a standard NIR I coating on both the front and back surfaces. This coating is designed to enhance the window's performance in the NIR spectrum, improving transmission and reducing reflection. The coating is part of Edmund Optics' NIR I series, which is known for its high quality and reliability.
The window has a flat geometry, which is ideal for applications that require a clear, undistorted view. The thin lens shape further enhances the window's optical performance, reducing aberrations and improving image quality.
