45-584 50 mm Dia. N-BK7 Precision Protective Flat Window; t=4 mm MgF2 400-700nm

This 45-584 optical window, sourced from Edmund Optics, is a high-precision component designed for protective applications. It features a base shape of a circle with a generous 50 mm diameter, making it suitable for a wide range of optical systems. The window has a thickness of 4 mm, providing a robust yet compact solution for your optical needs.

The window is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material, also known as Schott glass, offers a high refractive index and low dispersion, making it an ideal choice for many optical applications.

The window is coated with MgF2 on both the front and back surfaces. This coating, part of Edmund Optics' standard curve, is designed to enhance the window's performance in the 400-700 nm wavelength range. The coating reduces reflection, improving transmission and enhancing the overall efficiency of your optical system.

The window's geometry is defined as a thin lens, indicating its suitability for use in complex optical systems where precise control of light paths is required. Despite its thinness, the window's 4 mm thickness provides sufficient rigidity and protection for the optical components it is designed to safeguard.
