45-256 10 mm Dia. N-BK7 Precision Protective Flat Window; t=2 mm MgF2 400-700nm

This 45-256 item is a precision protective flat window offered by Edmund Optics. It features a 10 mm diameter and a thickness of 2 mm, making it a compact and robust option for various optical applications. The window is made of N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is often used in high-precision optical systems due to its superior performance.

The window is coated with MgF2 on both the front and back surfaces, which provides broadband anti-reflection properties in the 400-700 nm range. This coating enhances the window's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency. The MgF2 coating is standard and has a curve that is also provided by Edmund Optics.

The window's thin lens shape allows it to be used in various optical configurations, while its flat design ensures minimal optical aberrations.
