87-705 75 mm Dia. Calcium Fluoride Protective Flat Window; t=5 mm Uncoated

The 87-705 is a 75 mm diameter Calcium Fluoride (CaF2) protective flat window, with a thickness of 5 mm and no coating. Sourced from Edmund Optics, this window is a circular flat optical component designed for use in various applications.

The window's primary material is Calcium Fluoride, identified by the Material ID "caf2 mal-1963". This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. It is particularly useful in applications where high transmission in the UV range is required.

The window has a base shape of "Flat Window" and a "Thin Lens" shape, which means it is thin relative to its diameter. This makes it ideal for applications where minimal optical path deviation is required. The window is uncoated, meaning it does not have any additional layers to enhance its properties or protect it from environmental factors.

The window is designed to operate at a wavelength of 587.6 nm, which is in the visible light spectrum. This makes it suitable for applications that involve visible light.
