36-998 25 mm Dia. N-BK7 Precision Protective Flat Window; t=2 mm MgF2 400-700nm

This 36-998 optical component is a 25 mm diameter, 2 mm thick Flat Window, precision engineered from N-BK7 Schott glass. The window is coated with MgF2 on both the front and back surfaces, providing superior anti-reflective properties within the 400-700nm wavelength range.

The N-BK7 Schott glass, also known as BK7, is a popular choice for optical elements due to its excellent optical properties, including high transmittance in the visible spectrum and low auto-fluorescence. This makes it an ideal material for a wide range of applications, from imaging and laser systems to scientific research and industrial metrology.

The MgF2 coating on the window further enhances its performance by reducing surface reflections, thereby increasing the overall transmission of light through the window. This coating is particularly useful in high-power laser applications, where even small amounts of reflected light can cause significant damage to the system or pose safety risks.

The 36-998 Flat Window is designed with a Thin Lens shape, which provides excellent optical performance while minimizing weight and thickness. This makes it a versatile and practical choice for various applications, from beam delivery and protection to optical coupling and isolation.

The window is currently in stock and available for purchase from Edmund Optics. For more information, please refer to the provided weblink.
