47-684 50 mm Dia. Calcium Fluoride Protective Flat Window; t=3 mm Uncoated

The 47-684 is a 50 mm diameter Calcium Fluoride (CaF2) protective flat window, with a thickness of 3 mm and no coating. This window is sourced from Edmund Optics and is currently in stock, as indicated by its weblink status.

As a window, this component is designed to protect optical systems from environmental hazards such as dust, moisture, or mechanical damage, while minimally affecting the light path. Its base shape is circular, making it suitable for a wide range of applications.

The window is made of Calcium Fluoride, a material with the ID caf2 mal-1963. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum, making it an ideal choice for applications that require high transmission in these wavelengths.

The window has a diameter of 50 mm and a thickness of 3 mm. The diameter is a critical parameter as it determines the size of the optical system that the window can protect. The thickness, on the other hand, affects the window's mechanical strength and its ability to withstand external forces without breaking or deforming.

The window is uncoated, meaning it does not have any anti-reflective or other types of coatings. While coatings can enhance the performance of optical components, they are not always necessary. In this case, the uncoated design could be beneficial for applications that do not require coatings or for users who prefer to apply their own coatings.

The window is designed to work at a wavelength of 587.6 nm, which is in the visible spectrum. This makes it suitable for applications that involve visible light, such as imaging or laser systems.
