39-397 25.4 mm Dia. Zinc Selenide Protective Flat Window; t=3 mm Uncoated

The 39-397 is a 25.4 mm diameter Zinc Selenide (ZnSe) protective flat window, with a thickness of 3 mm and no coating. This window, sourced from Edmund Optics, is a type of flat window, characterized by its base shape being circular.

The window's geometry is defined by its diameter and thickness. With a diameter of 25.4 mm, it is suitable for a wide range of optical applications. The thickness of 3 mm provides robustness and stability, making it ideal for use in environments where the window may be subject to mechanical stress.

The material of the window is Zinc Selenide, identified by the Material ID 'znse marple-1964'. Zinc Selenide is a popular material in optical applications due to its excellent transmission properties in the infrared region of the spectrum. The window is uncoated, meaning it does not have any additional layers applied to enhance its optical properties or protect it from environmental factors.

The wavelength of 587.6 nm suggests that this window is designed for use in visible light applications. However, due to the properties of Zinc Selenide, it can also be used in infrared applications.

The window's shape is that of a thin lens, which means it has been manufactured to have minimal curvature, further enhancing its suitability for use as a protective window.
