This 39-411 Zinc Selenide (ZnSe) Protective Flat Window, offered by Edmund Optics, is a circular window with a diameter of 25.4 mm and a thickness of 5 mm. The window is made of ZnSe material, specifically identified as 'znse connolly' in the item data.
The window features a Broadband Anti-Reflective (BBAR) coating on both the front and back surfaces, specifically designed for the wavelength of 10600 nm. This coating is identified as 'edm dbbarl znse 312' in the item data. The BBAR coating reduces reflection and increases transmission, making it ideal for use in high-performance optical systems.
The window is designed in the shape of a Thin Lens, which is a lens with a very small focal length compared to its diameter. This design allows the window to be used in a variety of optical applications where a flat window may not provide the necessary optical performance.
