47-519 20 mm Dia. N-BK7 Precision Protective Flat Window; t=3 mm VIS 0 425-675nm

The 47-519 is a 20 mm diameter, 3 mm thick N-BK7 precision protective flat window, designed for use in the visible light spectrum (VIS) range of 425-675nm. This window is sourced from the reputable optical components vendor, Edmund Optics.

The window is designed in a flat format, featuring a circular base shape, making it suitable for a wide range of applications that require a transparent barrier without introducing any curvature-induced distortions. The window is constructed from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including high transmittance and low autofluorescence.

The window's geometry is defined by a 20 mm diameter and a 3 mm thickness, providing a robust and durable barrier while maintaining a high level of optical clarity. The window's coating is a standard VIS 0 coating, applied to both the front and back surfaces, which is designed to enhance its performance in the visible light spectrum. This coating follows the EDMM Vis-0 Standard Curve, ensuring consistent and reliable performance.

The window's shape is classified as a thin lens, indicating its suitability for use in optical systems where minimal optical power and distortion are required. The window is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
