45-575 15 mm Dia. N-BK7 Precision Protective Flat Window; t=3 mm Uncoated

The 45-575 is a 15 mm diameter, 3 mm thick uncoated flat window made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This window, sourced from Edmund Optics, is a precision protective component designed for various applications.

The window's geometry is circular with a 15 mm diameter, providing a wide viewing area or protection zone. The thickness of 3 mm ensures robustness and stability, making it suitable for use in environments where durability is a key factor. The uncoated surface allows for versatility in application, as it can be easily customized with a coating to suit specific needs.

The N-BK7 material, also known as BK7, is a borosilicate crown glass with a low refractive index and low dispersion. This makes it an ideal choice for applications that require high optical quality, such as imaging systems, beam delivery systems, and laser applications.

The window is designed in the shape of a thin lens, which can have a slight focusing effect depending on the application and the distance from the window. This can be beneficial in certain setups, providing a simple way to focus light without adding additional components.
