WZN4002 40 mm Dia. Zinc Selenide Standard Round Window; t=2mm Uncoated

The WZN4002 is a 40 mm diameter Zinc Selenide (ZnSe) standard round window with a thickness of 2 mm, uncoated. This window is sourced from Knight Optical, a reputable vendor known for its high-quality optical elements.

As a window, this component is designed to allow light or other electromagnetic radiation to pass through while providing protection for the optical system or component it is shielding. The WZN4002, specifically, is a flat window, which means it does not alter the path of the light passing through it, making it ideal for applications where minimal distortion is required.

The window's base shape is circular, which is a common choice due to its structural strength and ease of integration into various systems. The geometry of the WZN4002 includes a diameter of 40 mm and a thickness of 2 mm, providing a balance between strength, weight, and transparency.

The material of this window is Zinc Selenide (ZnSe), which is known for its excellent optical properties, including high transparency in the infrared region, making it suitable for applications in this spectrum, such as thermal imaging and night vision systems. The ZnSe used in this window is identified as 'znse marple-1964' in the vendor's catalog.

The WZN4002 is uncoated, meaning it does not have any additional layers applied to its surface to enhance its optical properties or protect it from environmental factors. This may be suitable for applications where such coatings are not required or desirable.
