At large temperature optical grade germanium is subject to abnormal absorption on account of greater variety of thermally produced holes. As it may be noticed from spectra absorption expansion turns into crucial at temperatures around about forty five°C.
Standard resistance for EMI quality Germanium is about four Ohm x cm but it surely depends on demanded degree of spurious signal suppression. Working with Ge window with such resistance these indicators are correctly shorted out and also the IR technique demonstrates superior performance.
