Ilensi yeSilicon(Si lens) yee-Infrared Applications

Ilensi yeSilicon yilensi yokubona eyenziwe ngesilicon.I-Silicon (Si) yinto yekristalline esetyenziswa ngokuqhelekileyo kwiinkqubo ze-infrared optical ezisebenza kwi-3 ukuya kwi-5µm yebhendi ye-spectral.Isalathisi sayo se-refractive sisondele kwi-3.4 kulo lonke uluhlu.Inoxinano oluphantsi ngokuthelekisayo phakathi kwezinto eziqhelekileyo ze-infrared, ezisisiqingatha kuphela se-Ge, i-GaAs kunye ne-ZnSe.Ke imathiriyeli yesilicon lukhetho olufanelekileyo lwenkqubo enenkxalabo yobunzima.I-silicon inzima kwaye inexabiso eliphantsi kunezona zinto zininzi eziqhelekileyo ze-infrared, zinciphisa iindleko zemathiriyeli ngelixa zinyusa iindleko zokwenziwa ngaxeshanye.

I-Silicon ifaneleka kakuhle kwisicelo se-MWIR kodwa ngenxa yokufunxa okunamandla ngaphezu kwe-6 micron, ayifanelekanga kwisicelo se-LWIR.Inokuthi isetyenziswe njengesiseko sesipili sokusetyenziswa kwelaser ngenxa ye-thermal conductivity, ubunzima obulula, kunye nokuqina.

I-Wavelength Infraredinokwenza imilo eyahlukeneyo yelensi yesiliconiplanethi, i-concave, i-convex, i-aspheric kunye nemigangatho edibeneyo.I-silicon idume kakhulu kwiinkqubo ezisebenza kwi-3-5µm yengingqi ye-spectral, ene-anti-reflective coatings (i-AR coating), ukuhanjiswa okuqhelekileyo kunokuziswa ukuya kwi-98%.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.

Ubude be-infraredyenza i-lens ye-silicon ye-aspheric esemgangathweni yesiko.Basenokujolisa okanye bahlukanise ukukhanya okungenayo ukuze bahlangabezane neemfuno ezithile zenkqubo ye-infrared.
