45-659 15 mm Dia. N-BK7 Precision Protective Flat Window; t=3 mm VIS-NIR 400-1000nm

The 45-659 is a high-precision protective flat window offered by Edmund Optics, designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to wavelengths between 400 and 1000 nanometers. This window boasts a circular base shape with a diameter of 15 millimeters and a thickness of 3 millimeters, making it an ideal solution for applications requiring a compact, yet robust optical component.

The window is crafted from N-BK7, a popular borosilicate crown glass manufactured by Schott, known for its excellent optical properties and versatility. N-BK7 is characterized by a low refractive index and low dispersion, making it suitable for a wide range of optical applications.

Both the front and back surfaces of the 45-659 window are coated with the EDM Vis-NIR 0SP200-2000 coating, specifically designed for the visible and near-infrared spectrum. This anti-reflection coating reduces surface reflections, enhancing transmission and improving overall system performance.

With its thin lens shape, the 45-659 window offers users a reliable and efficient solution for protecting optical components while minimizing the impact on the overall optical path. The window is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its valid weblink status.
