At superior temperature optical grade germanium is matter to extreme absorption on account of increased variety of thermally generated holes. As it could be observed from spectra absorption development results in being essential at temperatures over about 45°C.
Regular resistance for EMI grade Germanium is about 4 Ohm x cm nonetheless it will depend on required standard of spurious signal suppression. Working with Ge window with these kinds of resistance these indicators are properly shorted out along with the IR process demonstrates superior effectiveness.
