220-0103M 12.5 mm Dia. N-BK7 Precision Round Window; t=3 mm Uncoated

The 220-0103M is a precision round window offered by EKSMA Optics, a leading vendor in the optical components industry. This window, designed for use with lasers, features a 12.5 mm diameter and a thickness of 3 mm, making it a versatile option for various applications.

The window is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is often used in laser systems due to its low auto-fluorescence and high damage threshold. The N-BK7 Schott designation indicates that the glass meets the stringent quality standards set by Schott, a renowned glass manufacturer.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural reflective properties of the glass are desirable. However, for applications where reflective loss is a concern, coatings can be applied to reduce this effect.

The window's geometry is that of a thin lens, which can be beneficial in applications where the window needs to be as thin as possible to minimize distortion or where the window is used to focus or collimate a beam.
