87-700 12.5 mm Dia. Barium Fluoride Protective Flat Window; t=2 mm Uncoated

The 87-700 is a 12.5 mm diameter Barium Fluoride (BaF2) protective flat window, with a thickness of 2 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor in the optical industry. The item is currently in stock, as indicated by its weblink status.

As a flat window, this component is designed to protect optical surfaces from damage while minimally affecting the light path. Its base shape is circular, making it suitable for a wide range of applications. The window's geometry, defined by its diameter and thickness, ensures robustness and maintains the optical integrity of the system.

The material of this window, Barium Fluoride, is a common choice in the optical industry due to its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. This makes it an ideal choice for applications that require high transmission across a broad range of wavelengths.

The window's shape is that of a thin lens, which, despite its name, does not focus or diverge light. Instead, it merely changes the direction of the light passing through it. This is particularly useful in systems where the light path needs to be altered without introducing aberrations.

Notably, this window is uncoated. While coatings can enhance the performance of optical components by reducing reflections, increasing transmission, or providing other benefits, an uncoated window can be the best choice for certain applications. For instance, it may be preferred when the coating could introduce unwanted spectral characteristics or when cost is a significant factor.
