This is a ZnSe-W-50.8-3 Flat Window, a high-quality optical component sourced from Alkor Technologies. The window, which features a base shape of a circle, has a diameter of 50.8 mm and a thickness of 3 mm, making it suitable for a wide range of optical applications.
The material of this window is ZnSe, which is known for its excellent optical properties, including high transparency in the infrared region, making it ideal for use in systems operating at a wavelength of 10600 nm. The window is uncoated, which means it does not have any additional layers applied to its surface to alter its optical properties.
The window is designed in the shape of a thin lens, which can help to reduce optical aberrations in some applications. It is important to note that the window is uncoated, which means it does not have any additional layers applied to its surface to alter its optical properties.
