Typical resistance for EMI grade Germanium is about four Ohm x cm but it depends upon required volume of spurious signal suppression. Employing Ge window with these resistance these alerts are successfully shorted out along with the IR method reveals good performance.
It is also well worth noting that germanium is fairly far more brittle that silicon and therefore must be cope with with treatment in the course of machining.
The simplest way to thoroughly clean the Home windows is to work with possibly ethanol, isopropyl Liquor, methanol, reagent-grade acetone or lint-free of charge lens cloths. You can also use nitric acid but this material, although all right for germanium can corrode other optics or mounts That could be close by in your technique.
Thickness of Germanium window needed to resist tension differential at opposite sides can be calculated by the subsequent equation:
