220-0163M 12.5 mm Dia. N-BK7 Precision Round Window; t=6 mm Uncoated

The 220-0163M is a precision round window offered by EKSMA Optics, a leading vendor in the field of optical components. This window, designed for use with lasers, features a 12.5 mm diameter and a thickness of 6 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 additional layers applied to its surface. This can be beneficial in applications where the user wants to minimize reflection or where specific coatings are not required. However, it's important to note that uncoated windows may be more susceptible to environmental factors such as dust and moisture.

The window's geometry is that of a thin lens, which can be advantageous in certain applications due to its minimal thickness and weight. This can be particularly beneficial in systems where space and weight are critical factors.

The window is designed for use with a wavelength of 633 nm, making it suitable for a wide range of laser systems. However, it's always important to check the compatibility of any optical component with your specific system to ensure optimal performance.
