This is a 25.4 mm diameter Germanium Flat Window, offered by Alkor Technologies. The window, which has a thickness of 4mm, is uncoated, providing a clear, unaltered view of the spectrum it is designed to transmit.
Germanium is a popular material for optical windows due to its wide transmission range, which includes the infrared region. This particular window is designed to transmit wavelengths of 10600 nm, making it suitable for a range of applications in the infrared spectrum.
The window is of the 'flat window' type, which means it is designed to provide a clear view without any curvature or distortion. This makes it ideal for use in applications where a flat, undistorted view is required. The 'thin lens' shape further ensures that the window does not introduce any significant optical aberrations.
