83-474 30 mm Dia. N-BK7 Precision Protective Flat Window; t=4 mm NIR I 600-1050nm

The 83-474 is a 30 mm diameter, 4 mm thick N-BK7 flat window, coated with Edmund Optics' NIR I standard curve on both the front and back surfaces. This window is sourced from Edmund Optics, a leading global manufacturer of optical components.

The window is made from N-BK7, a popular borosilicate crown glass known for its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high optical performance and precision. The window's 30 mm diameter and 4 mm thickness provide a robust and stable platform for various optical systems.

The window's coating, the Edmund Optics' NIR I standard curve, is applied to both the front and back surfaces. This coating is designed to optimize the window's performance in the near-infrared region, specifically between 600 and 1050 nanometers. It enhances the window's transmittance in this region, reducing reflection and improving overall system performance.

The window's thin lens shape further enhances its optical performance, focusing light and reducing spherical aberration. This makes it suitable for use in a wide range of applications, including imaging systems, beam delivery systems, and optical metrology.
