47-947 50.0 x 50.0 mm N-BK7 Precision Protective Flat Window; t=4 mm VIS-NIR 400-1000nm

The 47-947 is a 50.0 x 50.0 mm N-BK7 Precision Protective Flat Window with a thickness of 4 mm, specifically designed for the visible (VIS) and near-infrared (NIR) spectrum of 400-1000nm. This window is sourced from the renowned optical component vendor, Edmund Optics.

This optical element is classified as a Window, more specifically, a Flat Window, due to its rectangular base shape and thin lens design. The window's dimensions are 50.0 mm in width and 50.0 mm in length, making it a square-shaped component. The thickness of the window is 4 mm, providing robustness and durability.

The window is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material is widely used in various optical applications, including laser systems, beam delivery systems, and optical imaging systems.

The 47-947 window features a coating on both the front and back surfaces, specifically the EDm VIS-NIR 0SP200-2000 coating. This coating is designed to enhance the window's performance in the VIS-NIR spectrum, providing improved transmission and protection against environmental factors.
