No water solubility- gain around salty Home windows including KBr and NaCl which might be extremely hygroscopic.
Cautious handling and cleansing: Germanium optics are exceptionally tricky and brittle. Good cleaning and packaging processes decrease any damage or contamination that could have an impact on its optical functionality.
In truth, at a watch-popping Knoop Hardness of 2000kg/mm2, one could possibly ponder, why wouldn’t I just use sapphire windows rather than germanium? Though sapphire will be the undisputed winner of robust optics in the UV/VIS and mid-IR by using a wavelength selection that dips in to the much UV selection at 150nm, it may possibly only be utilized as much as 4.
