210-0103M 12.5 mm Dia. N-BK7 Flat Round Window; t=3 mm Uncoated

The 210-0103M is a Flat Round Window offered by EKSMA Optics, a renowned vendor in the optical components industry. This window, with a base shape of a circle, has a diameter of 12.5 mm and a thickness of 3 mm, making it a compact and robust option for various applications.

The window is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. Schott, a leading glass manufacturer, supplies this material, ensuring high quality and reliability. The N-BK7 material is known for its low dispersion and high Abbe number, making it an ideal choice for applications that require high optical performance and precision.

The window is designed for a wavelength of 633 nm, making it suitable for a wide range of applications, including laser systems and optical metrology. The window's shape is that of a thin lens, which contributes to its minimal weight and ease of integration into optical systems.

Notably, this window is uncoated, meaning it does not have any additional layers of material applied to its surface. While coatings can enhance certain optical properties, an uncoated window offers simplicity and versatility, making it suitable for various applications where specific coatings are not required.
