At high temperature optical quality germanium is subject matter to abnormal absorption on account of enhanced quantity of thermally generated holes. As it might be viewed from spectra absorption progress turns into essential at temperatures over about 45°C.
Earlier mentioned benefit are generic specs for fabrication, precise better value may very well be obtainable and must be reviewed circumstance by case.
Additionally it is value noting that germanium is fairly far more brittle that silicon and so must be take care of with care throughout machining.
