220-0722E 76.2 mm Dia. N-BK7 Precision Round Window; t=12.7 mm Uncoated
The 220-0722E is a precision round window offered by EKSMA Optics, a leading vendor in the optical components industry. This window, designed for use with lasers, boasts a base shape of a flat circle and is constructed from N-BK7 glass, a material well-known for its excellent optical properties.
The window has a diameter of 76.2 mm and a thickness of 12.7 mm, making it suitable for a wide range of applications. It is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where the natural properties of the glass are desired.
The window is designed to be used at a wavelength of 633 nm, making it suitable for use with helium-neon lasers, among others. Its geometry is that of a thin lens, which can be advantageous in applications where a thin, lightweight optical element is required.
