At large temperature optical grade germanium is matter to too much absorption resulting from enhanced number of thermally produced holes. As it may be observed from spectra absorption advancement gets essential at temperatures above about forty five°C.
It can be broadly believed that sure international locations including the United states of america and China hold stock – nationwide stockpiles – of germanium, thanks to expected new developments in complex programs together with its current worth in military and aerospace infrared imaging tools.
It's also worthy of noting that germanium is fairly more brittle that silicon and so must be deal with with treatment in the course of machining.
