Germanium joalo ka kristale ea mono e sebelisoang haholo ho semi-conductor ha e monye libakeng tsa 2μm ho isa ho 20μm IR.E sebelisoa mona e le karolo ea optical bakeng sa lits'ebetso tsa sebaka sa IR.
Germanium ke lisebelisoa tse phahameng tse sebelisoang ho etsa liprism tsa Attenuated Total Reflection (ATR) bakeng sa spectroscopy.Lenane la eona la refractive ke hore Germanium e etsa hore ho be le 50% beamsplitter ea tlhaho e sebetsang ntle le tlhokahalo ea ho roala.Germanium e boetse e sebelisoa haholo joalo ka substrate bakeng sa tlhahiso ea li-filters tsa optical.Germanium e akaretsa sehlopha sohle sa 8-14 micron thermal band mme e sebelisoa lits'ebetsong tsa lense bakeng sa ho nka litšoantšo ka mocheso.Germanium e ka ba AR e koahetsoeng ka Diamond e hlahisang optic e ka pele e thata haholo.
Germanium e lengoa ka mokhoa oa Czochralski ke bahlahisi ba fokolang ba Belgium, USA, Chaena le Russia.Lenane la refractive la Germanium le fetoha ka potlako ka mocheso 'me thepa e fetoha opaque ka nako eohle ea wavelengths ka holimo ho 350K ha lekhalo la lihlopha le tlala lielektrone tsa mocheso.
Kopo:
• E loketse lits'ebetso tse haufi le IR
• Broadband 3 ho 12 μm anti-reflection coating
• E loketse lits'ebetso tse hlokang ho hasana ho tlase
• E kholo bakeng sa lisebelisoa tsa laser tse tlaase tsa CO2
Sebopeho:
• Lifensetere tsena tsa germanium ha li fetisoe sebakeng sa 1.5µm kapa ka tlase, ka hona ts'ebeliso ea eona e kholo e libakeng tsa IR.
• Lifensetere tsa Jeremane li ka sebelisoa litekong tse fapaneng tsa infrared.
