11-861 150 mm Dia. N-BK7 Precision Protective Flat Window; t=10 mm MgF2 400-700nm

This 11-861 optical window, sourced from Edmund Optics, is a high-precision component designed for protective applications. It features a circular base shape with a generous 150 mm diameter, making it suitable for a wide range of optical systems. The window boasts a thickness of 10 mm, providing robustness and stability.

The window is made from N-BK7, a popular 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, standard from Edmund Optics, is designed to provide high transmission in the 400-700 nm range, making it suitable for use in visible light applications. The coating is also known for its durability and resistance to environmental factors, ensuring long-lasting performance.

The window is shaped as a thin lens, which can be beneficial in certain optical configurations. However, it's important to note that this window does not have any focusing or magnifying properties due to its thin lens shape.
