Applications of germanium lenses
1. Thermal imaging cameras: germanium lenses are widely used in thermal imaging cameras due to their excellent transmission properties in the mid- and far-infrared wavelength bands.
2. Infrared thermometry: in infrared thermometry equipment, germanium lenses are used to focus infrared radiation in order to accurately measure the temperature of an object.
3. Infrared lenses: germanium lenses are also used to make infrared lenses that provide clear imaging at infrared wavelengths for night vision or other low light environments.
4. Co2 lasers: the wide spectral operating range of germanium lenses and their opacity in the visible spectral range make them well suited for infrared laser applications, such as Co2 lasers.
5. Defense military : germanium lenses are also used in infrared detection and guidance systems in the defense military field due to their excellent performance in the infrared band.
6. Scientific research: in the field of scientific research, germanium lenses are used in a variety of infrared spectral analysis instruments, such as Fourier Transform Infrared Spectroscopy (FTIR), for the study of the molecular structure and chemical bonding of substances.
