Standard resistance for EMI quality Germanium is about four Ohm x cm but it is dependent upon demanded degree of spurious signal suppression. Working with Ge window with such resistance these signals are efficiently shorted out as well as IR system exhibits very good general performance.
5µm. This leaves germanium as the most effective and only option for brutally challenging IR programs. This is often why you will note germanium windows and lenses serving in locations as inhospitable as outer House, battlefields and in the midst of high-driven CO2 laser units. A lot more on this later on.
