WBF2502 25.4 mm Dia. Barium Fluoride Round Window; t=2mm Uncoated

The WBF2502 is a 25.4 mm diameter Barium Fluoride (BaF2) round window with a thickness of 2mm, uncoated. This optical window is sourced from Knight Optical, a reputable vendor known for its extensive catalog of 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 path deviation. The window's base shape is circular, a common choice for components intended for wide-angle applications or where uniform illumination is required.

The material of this window is Barium Fluoride (BaF2), a high-performance optical material known for its excellent transparency across a wide spectral range, including the ultraviolet, visible, and infrared regions. This makes the WBF2502 a versatile component for various optical systems.

The window's geometry is defined by its diameter and thickness. With a diameter of 25.4 mm, it provides a generous aperture for light transmission. The thickness of 2mm ensures structural rigidity while minimizing optical distortions.

Notably, this window is uncoated, meaning it does not have any anti-reflective or other surface treatments. This may be advantageous in applications where such coatings are not required or desirable, such as where broadband transmission is needed, or where the risk of coating damage is high.
