220-0191 20.0 mm Dia. N-BK7 Precision Round Window; t=3 mm Uncoated

The 220-0191 is a precision round window, designed and manufactured by EKSMA Optics, a leading vendor in the optical components industry. This window is specifically crafted for laser applications and features a base shape of a circle with a diameter of 20.0 mm and a thickness of 3 mm.

The window is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The N-BK7 Schott used in this window ensures high transmittance and low dispersion, making it ideal for various laser applications.

The window is designed in a thin lens shape, which is beneficial for applications where weight and space are critical factors. Despite its thinness, the window maintains high durability and resistance to external factors.

This particular window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance certain optical properties, an uncoated window offers simplicity and versatility, making it suitable for a wide range of applications.
