47-522 40 mm Dia. N-BK7 Precision Protective Flat Window; t=4 mm VIS 0 425-675nm

The 47-522 is a 40 mm diameter, 4 mm thick N-BK7 precision protective flat window, designed for use in the visible light spectrum (425-675nm). This window is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock with valid weblinks provided for easy access to additional information.

As a flat window, this component is designed to protect optical systems from environmental hazards such as dust, dirt, and moisture, while minimally affecting the light path. Its 40 mm diameter and 4 mm thickness make it suitable for a wide range of applications, from scientific research to industrial inspection.

The window is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is particularly suitable for use in the visible light spectrum, ensuring high transmittance and clarity.

The window features a standard coating on both the front and back surfaces, specifically the EDMM Vis-0 coating. This coating is designed to provide superior anti-reflection properties, further enhancing the window's performance in its intended light spectrum.

The window's shape is described as a thin lens, indicating its minimal curvature and focus capabilities. This makes it an ideal choice for applications where a flat, protective surface is required without the need for significant refractive power.
