It is also worthy of noting that germanium is relatively additional brittle that silicon and as a consequence needs to be cope with with care during machining.
Apparently, due to its identical crystal composition to Diamond might be coated using a DLC layer (Diamond Like Carbon) which in addition to cutting down the reflection on it’s floor, adds a diamond sturdy protecting layer. Finally Germanium is just not clear within the obvious which can be handy to give attention to IR mild.
