Diamond has the widest transmission spectrum among all solid materials available, ranging from 225nm in the ultraviolet to 25 μm in the infrared (except for wavelengths of 1.8 μm-2.5 μm), as well as excellent transmission in the microwave range. Due to its excellent optical properties, strong resistance to radiation damage, strong hardness, high thermal conductivity, high chemical stability, and low coefficient of expansion, diamond is an ideal material for the production of modern infrared optical windows.
