220-0101M 12.5 mm Dia. N-BK7 Precision Round Window; t=3 mm Uncoated

The 220-0101M 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 12.5 mm diameter and a thickness of 3 mm, making it a versatile and robust 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 precision optics due to its low coefficient of thermal expansion, high homogeneity, and exceptional transmission in the visible and near-infrared spectral ranges. The N-BK7 Schott designation indicates that the glass meets the stringent quality standards set by Schott, a renowned glass manufacturer.

The window features a flat geometry, which is ideal for applications that require minimal optical distortion. The uncoated surface ensures broadband transmission but may lack some of the protective benefits that anti-reflective or other specialized coatings can provide.

This window is currently in stock and available for immediate purchase. For more information, including pricing and technical specifications, please refer to the vendor's website.
