49-124 9 mm Diameter N-BK7 Precision Protective Flat Window; t=2 mm VIS-NIR 400-1000nm
The 49-124 is a 9 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. This window is sourced from Edmund Optics, a leading vendor known for their high-quality optical components.
The window is coated with the EDM VIS-NIR 0SP2002000 coating on both the front and back surfaces. This anti-reflection coating is designed to minimize surface reflections and increase transmission in the visible and near-infrared regions (400-1000nm), making it ideal for applications that require high transmission and low loss, such as imaging systems, beam delivery systems, and spectroscopy.
The window's thin lens shape allows it to be used in various optical systems without significantly altering the beam path or introducing aberrations. The 9 mm diameter provides a good balance between light gathering capability and ease of integration into various systems. The 2 mm thickness offers sufficient mechanical strength while maintaining low weight and a compact form factor.
