Watchful managing and cleansing: Germanium optics are very challenging and brittle. Right cleansing and packaging procedures decrease any destruction or contamination that may influence its optical performance.
The truth is, at an eye-popping Knoop Hardness of 2000kg/mm2, a single may possibly marvel, why wouldn’t I just use sapphire windows rather than germanium? Whilst sapphire will be the undisputed champion of strong optics in the UV/VIS and mid-IR with a wavelength range that dips in to the far UV range at 150nm, it may possibly only be made use of around four.
