This is a 25 mm diameter Germanium Flat Window, model GE-W-25.0-1, available from Alkor Technologies. The window is uncoated and has a thickness of 1 mm, making it a versatile and practical option for various applications.
The window is designed in a flat shape, which is ideal for applications that require a clear, unobstructed view. The base shape is circular, providing a symmetrical and aesthetically pleasing design. The window is made of Germanium burnett, a material known for its excellent optical properties, particularly its high refractive index and transparency in the infrared region.
The window is designed to work at a wavelength of 10600 nm, making it suitable for applications in the infrared spectrum. It is categorized as a thin lens, indicating its ability to focus or disperse light without significant distortion.
The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in applications where the natural properties of Germanium are desired, or where cost or simplicity are considerations. However, it's important to note that uncoated windows may have higher reflectivity and may not perform as well in certain environments compared to coated windows.
The window is currently in stock and more information can be found on Alkor Technologies' website.
