220-0726E 76.2 mm Dia. N-BK7 Precision Round Window; t=12.7 mm Uncoated

The 220-0726E is a precision round window offered by EKSMA Optics, a leading vendor in the optical components industry. This window, designed for use with laser systems, boasts a diameter of 76.2 mm and a thickness of 12.7 mm, making it a robust and reliable 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 chosen for its low optical dispersion and high Abbe number, making it an ideal choice for applications that require high precision and accuracy. The N-BK7 Schott variant used in this window ensures superior optical performance.

The window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance certain properties of an optical component, such as reducing reflection or increasing transmission, an uncoated window can be advantageous in certain applications where specific coatings may not be required or desired.

This window is designed in the shape of a thin lens, which can be beneficial in applications where a flat surface is not feasible or desirable. The lens shape can help to redirect or focus light, making it a versatile option for various laser systems.
