39-398 25.4 mm Dia. Zinc Selenide Protective Flat Window; t=5 mm Uncoated

The 39-398 is a 25.4 mm diameter Zinc Selenide (ZnSe) protective flat window, with a thickness of 5 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor in the optical industry.

The window is designed as a flat window, which is a type of optical window that does not alter the path of light. It has a base shape of a circle, which is the most common shape for optical components due to its isotropic properties.

The material of the window is Zinc Selenide, identified in the item data as 'znse marple-1964'. Zinc Selenide is a popular material for optical windows due to its excellent transmission properties in the infrared region of the spectrum. It is also chemically stable and resistant to environmental conditions, making it suitable for use in various applications.

The window is designed for use at a wavelength of 587.6 nm, which is in the visible light spectrum. This makes it suitable for applications that require visibility, such as in imaging systems.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in applications where coatings may interfere with the performance of the system.
