WBF2501 25 mm Dia. Barium Fluoride Round Window; t=2mm Uncoated

The WBF2501 is a 25 mm diameter Barium Fluoride (BaF2) round window with a thickness of 2 mm, uncoated. This optical window is sourced from Knight Optical, a reputable vendor known for providing high-quality optical components.

This window is categorized as a flat window due to its planar geometry, making it suitable for applications that require minimal optical distortion. The window's base shape is circular, a common choice for applications that require uniform light transmission.

The material of this window is Barium Fluoride (BaF2), which is characterized by its high transparency in the ultraviolet (UV), visible, and infrared (IR) regions of the spectrum. This makes it an ideal choice for applications that require broadband transmission, such as spectroscopy and laser systems.

The window has a wavelength of 633 nm, which is within the visible spectrum. This specific wavelength is often used in applications such as laser-based measurements and bioimaging.

The window's shape is described as a thin lens, indicating that it has been precisely manufactured to have minimal curvature. This is beneficial for applications that require minimal optical power and distortion.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be advantageous for applications that require high damage threshold or where coatings may introduce unwanted reflections or absorptions.

The window is currently in stock and available for immediate purchase from Knight Optical's website.
