49-121 9 mm Dia. N-BK7 Precision Protective Flat Window; t=2 mm Uncoated

The 49-121 is a 9 mm diameter, 2 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-ground and polished component designed to protect optical surfaces from damage while minimally affecting the light path.

The N-BK7 Schott material, also known as BK7, is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for various optical applications. The window's 2 mm thickness provides sufficient strength and rigidity while maintaining minimal optical distortion.

This Flat Window does not come with any coating, which means it is uncoated. While coatings can enhance specific optical properties, such as reducing reflection or increasing transmission, an uncoated window like this one offers simplicity and versatility, making it suitable for a wide range of applications.

With a 9 mm diameter, this Flat Window is compatible with many optical systems and components. Its thin lens shape ensures easy integration into existing setups, allowing for optimal performance and protection.
