45-657 10 mm Diameter N-BK7 Precision Protective Flat Window with VIS-NIR 400-1000nm Coating

The 45-657 is a 10 mm diameter, 2 mm thick Flat Window made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and high Abbe number. This window is sourced from Edmund Optics, a leading vendor known for their high-quality optical components.

The window features a VIS-NIR coating, specifically the EDMM VisNIR0SP2002000 coating on both the front and back surfaces. This anti-reflection coating is designed for the visible and near-infrared spectrum, ranging from 400 to 1000 nanometers. The coating reduces surface reflections, enhancing transmission and improving overall system performance.

The window's thin lens shape and circular geometry make it suitable for a wide range of applications. It can serve as a protective layer, a mounting platform, or a simple optical element in various setups. The window's 2 mm thickness provides sufficient robustness while maintaining a low profile, making it ideal for compact systems.

Please note that the window's Abbe number, a measure of dispersion, is approximately 64.21, and its refractive index at the specified wavelength (587.6 nm) is around 1.5168. These parameters can be crucial in designing and simulating optical systems.
