45-660 20 mm Dia. N-BK7 Precision Protective Flat Window; t=3 mm VIS-NIR 400-1000nm
The 45-660 is a 20 mm diameter, 3 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 reputable 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 coating is designed for the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. It enhances the window's performance by reducing reflection and increasing transmission, making it ideal for applications that require high light transmission in this spectral range.
The window's thin lens shape and circular geometry provide versatility in integration with various optical systems. The 3 mm thickness offers a good balance between mechanical strength and light transmission, while the 20 mm diameter allows for a wide range of applications.
This window is part of Edmund Optics' extensive catalog and is currently in stock, ensuring quick delivery for your optical project needs. For more information, you can refer to the vendor's website through the provided weblink.
