This is a WBF2510 Barium Fluoride (BaF2) round window, sourced from Knight Optical. The window has a diameter of 25.4 mm and a thickness of 1 mm, making it a thin and lightweight option for various optical applications.
The window is made of Barium Fluoride, a material with a wide transparency range, extending from the ultraviolet to the far infrared. This makes it an ideal choice for applications that require broadband transmission, such as spectroscopy and laser systems. The window is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The window is of the flat variety, which means it does not have any curvature. This is beneficial in applications where flatness is critical, such as in beam splitters or in optical systems where distortion needs to be minimized. The window's geometry is that of a thin lens, which suggests that it can be used in systems where focusing or collimation is required.
