WBF1605 16 mm Dia. Barium Fluoride Round Window; t=0.5mm Uncoated

The WBF1605 is a 16 mm diameter Barium Fluoride (BaF2) round window, with a thickness of 0.5mm, uncoated. This optical component is sourced from Knight Optical, a reputable vendor known for its wide range of high-quality optical elements.

The window is designed with a flat surface, making it suitable for applications that require a simple, non-refracting optical interface. Its circular base shape adds to its versatility, allowing it to be used in various optical systems.

The material of this window is Barium Fluoride, identified by the Material ID "baf2 cgdm". Barium Fluoride is a popular choice for optical components due to its excellent transparency in the ultraviolet, visible, and infrared regions of the spectrum. This makes the WBF1605 suitable for a wide range of applications, including UV, visible, and IR spectroscopy, as well as laser systems.

The window has a wavelength of 633nm, which is within the visible spectrum. This further expands its potential applications, especially in systems where visual observation or monitoring is required.

The window is shaped as a thin lens, which, despite its name, does not have any refractive power. This shape is often used in optical systems where a simple, flat interface is required.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be advantageous in certain applications where a specific coating might interfere with the optical properties of the system. However, it's important to note that uncoated surfaces can be more susceptible to contamination and damage, so handling and cleaning should be done with care.
