Ze Windows-joalo ka Lifilimi tsa Long-wave Pass

Lenane la refractive la thepa ea germanium le phahame haholo (hoo e ka bang 4.0 sehlopheng sa 2-14μm). Ha e sebelisoa e le khalase ea fensetere, e ka koaheloa ho latela litlhoko tsa ho ntlafatsa phetisetso ea sehlopha se lumellanang. Ho feta moo, thepa ea phetisetso ea germanium e na le maikutlo a matla haholo ho liphetoho tsa mocheso (phetisetso e fokotseha ka ho eketseha ha mocheso). Ka hona, li ka sebelisoa feela ka tlase ho 100 ° C. Boima ba germanium (5.33 g / cm3) bo lokela ho nkoa ha ho etsoa litsamaiso tse nang le litlhoko tse thata tsa boima. Lifensetere tsa Germanium li na le mefuta e mengata ea phetisetso (2-16μm) 'me li opaque ka har'a mefuta e bonahalang ea spectral, e leng se etsang hore li tšoanelehe ka ho khetheha bakeng sa lisebelisoa tsa laser ea infrared. Germanium e na le knoop e thata ea 780, hoo e ka bang habeli ho thatafala ha magnesium fluoride, e leng se etsang hore e tšoanelehe haholoanyane bakeng sa lits'ebetso lefapheng la IR la ho fetola optics.
Kopo: Lilense tsa Germanium li sebelisoa haholo ho thermometers ea infrared, litšoantšo tsa mocheso oa infrared, lasers ea Co2 le lisebelisoa tse ling. Melemo ea rona: Jiite e hlahisa lilense tsa germanium, e sebelisa kristale germanium ea optical grade single germanium e le thepa ea motheo, e sebelisa theknoloji e ncha ea polishing ho sebetsa, bokaholimo bo na le ho nepahala ho holimo haholo, 'me mahlakoreng a mabeli a lense ea germanium e tla koahetsoe ka 8-14μm anti. -reflection coating , e ka fokotsa ho bonahatsa ha substrate, 'me phetisetso ea seaparo sa anti-reflection sehlopheng se sebetsang se fihla ho feta 95● Boitsebiso: Ge (germanium)
