ILens yeGermanium(Ge lens) yosetyenziso lwe-Infrared

Ilensi yeGermanium yilensi yokukhanya eyenziwe ngegermanium.I-Germanium (Ge) yimathiriyeli eyikristale enesona salathisi siphezulu se-refractive (4.002@11µm) sezinto ezisetyenziswa ngokuqhelekileyo kwimathiriyeli ye-infrared.Kananjalo inokusasazwa okuphantsi ngokuthelekisayo, ubunzima obuphezulu kunye nokuxinana.Ngenxa yoluhlu olubanzi lokuhambisa (ngaphezu kwe-45% kwi-2-12 micron band) kunye ne-opaque kwi-UV kunye nokukhanya okubonakalayo, i-Germanium ifaneleka kakuhle kwisicelo se-IR esifana neenkqubo zokucinga ze-thermal, izicelo ze-infrared field kunye nezixhobo zokuhlalutya ngokuchanekileyo.

I-Germanium ikwaphantsi kwe-thermal runaway.Ngokukhula kobushushu, ukufunxa kukhula ngokukhawuleza okukhulu.Ngenxa yesi siphumo sokubaleka kwe-thermal, i-germanium lens ayifanelekanga ukusetyenziswa kumaqondo obushushu angaphezu kwe-100°C.

I-Wavelength Infrared inokuvelisa imilo eyahlukeneyo yelensi yegermanium ngenqwelomoya, i-concave, i-convex, i-aspheric kunye ne-diffractive surface.I-Germany idume kakhulu kwiinkqubo ezisebenza kwi-3-5 okanye i-8-12µm kummandla we-spectral, kunye neengubo ezichasene ne-reflective (i-AR coating), ukuhanjiswa okuqhelekileyo kunokunyuswa ukuya kwi-97.5-98.5% kuxhomekeke kwi-bandwidth ye-coating.Sinokufaka i-diamond-efana ne-carbon coating (i-DLC coating) okanye i-coating ephezulu ehlala ixesha elide (i-HD i-coating) kumphezulu we-lens ukubonelela ngokhuseleko olongezelelweyo malunga nokuqala kunye nefuthe.

I-Wavelength infrared yenza umgangatho we-aspherical spherical kunye neaspheric germanium lens.Basenokujolisa okanye bahlukanise ukukhanya okungenayo ukuze bahlangabezane neemfuno ezithile zenkqubo ye-infrared.Isicelo sinokuba ngumfanekiso we-thermal, i-thermograph, i-beam collimating, uhlalutyo lwe-spectrum kunye njl.
