Our germanium lenses Possess a substantial refractive index—the very best refractive index among the readily available IR transmitters. In addition, it exhibits nominal chromatic aberration due to minimal dispersion.
fiveµm. This leaves germanium as the most beneficial and only option for brutally hard IR purposes. This is typically why you will see germanium windows and lenses serving in locations as inhospitable as outer Area, battlefields and in the course of substantial-driven CO2 laser programs.
