The 210-0202M is a Flat Round Window with a diameter of 25.0 mm, sourced from EKSMA Optics. This window is designed for use in optical systems and features a base shape of a circle, which is a common geometry in optical components due to its symmetry and ease of integration.
The window is made from N-BK7, a popular optical glass due to its excellent optical properties and wide transmission range. This particular window has a thickness of 2 mm, providing a good balance between durability and light transmission. The uncoated nature of this window means it does not have any anti-reflective or other coatings, making it suitable for use in applications where such coatings are not required or desirable.
The window is designed to operate at a wavelength of 633 nm, which is within the visible light spectrum. This makes it suitable for use in a wide range of applications, including laser systems, optical imaging, and beam shaping.
