Ilensi ye-infrared ephakathi kwamazaes (Ilensi ye-MWIRes) zizinto ezibaluleke kakhulu ezisetyenziswa kwiintlobo ngeentlobo zezicelo ezifuna umfanekiso we-thermal, njengokucupha, ukufunyanwa kwethagethi, kunye nohlalutyo lwe-thermal. Ezi lensi zisebenza kwingingqi ye-infrared ephakathi kwe-electromagnetic spectrum, phakathi kwe-3 kunye ne-5 microns (3-5um lens), kwaye ziyilelwe ukugxila kwimitha ye-infrared kuluhlu lwesixhobo.
Iilensi ze-MWIR zenziwe ngezinto ezinokusasaza kwaye zijolise kwimitha ye-IR ngaphakathi kwingingqi ye-MWIR. Izinto eziqhelekileyo ezisetyenziselwa iilensi ze-MWIR ziquka igermanium, isilicon, kunye neeglasi ze-chalcogenide. I-Germanium yeyona nto isetyenziswa ngokuxhaphakileyo kwiilensi ze-MWIR ngenxa yesalathiso sayo esine-refractive ephezulu kunye neempawu zothumelo ezilungileyo kuluhlu lwe-MWIR.
Ilensi ye-MWIR iza kuyilo olwahlukeneyo kunye nolungelelwaniso, ngokuxhomekeke kwisicelo esicetywayo. Olunye lolona yilo luqhelekileyo yi-lens yeplano-convex elula, enomphezulu othe tyaba kunye nomphezulu omnye weconvex. Le lens kulula ukuyenza kwaye isetyenziswa kwizicelo ezininzi apho kufuneka inkqubo yokucinga esisiseko. Olunye uyilo lubandakanya iilensi eziphindwe kabini, eziqulathe iilensi ezimbini ezinezalathisi ezahlukeneyo zokuphinda zikhanye, kunye neelensi zokusondeza, ezinokuhlengahlengisa ubude bojoliso ukuze usondeze ngaphakathi okanye ngaphandle entweni.
Iilensi ze-MWIR zizinto ezibalulekileyo kwiinkqubo ezininzi zokucinga ezisetyenziswa kuluhlu lwamashishini. Emkhosini, iilensi ze-MWIR zisetyenziswa kwiinkqubo zokucupha, iinkqubo zesikhokelo somjukujelwa, kunye neenkqubo zokufumana ekujoliswe kuzo. Kwiimeko zoshishino, iilensi ze-MWIR zisetyenziselwa uhlalutyo lwe-thermal kunye neenkqubo zokulawula umgangatho. Kwizicelo zonyango, iilensi ze-MWIR zisetyenziswa kumfanekiso oshushu woxilongo olungena-invasive.
Enye into ebalulekileyo eqwalaselwayo xa ukhetha ilensi ye-MWIR bubude bayo obugxile kuyo. Ubude be-lens bumisela umgama phakathi kwelensi kunye noluhlu lwe-detector, kunye nobukhulu bomfanekiso oveliswayo. Umzekelo, i-lens enobude obufutshane obugxininisiweyo iya kuvelisa umfanekiso omkhulu, kodwa umfanekiso uya kuba neenkcukacha ezincinci. Ilensi enobude obude bokujolisa iya kuvelisa umfanekiso omncinci, kodwa umfanekiso uya kuba neenkcukacha ngakumbi, njenge.50mm MWIR Ilensi.
Olunye uqwalaselo olubalulekileyo luyisantya se-lens, esichongwa yi-f-number yayo. I-f-inombolo ngumlinganiselo wobude obugxilwe kububanzi belensi. Ilensi enenani eliphantsi lika-f iya kukhawuleza, oku kuthetha ukuba inokubamba ukukhanya ngakumbi ngexesha elifutshane, kwaye ihlala ikhethwa kwiimeko zokukhanya okuphantsi.
Ukuqukumbela, iilensi ze-MWIR ziyinxalenye ebalulekileyo kwiinkqubo ezininzi zokucinga ezisetyenziswa kuluhlu lwamashishini. Ziyilelwe ukugxila kwimitha ye-infrared kwi-detector array kwaye zize kuyilo olwahlukeneyo kunye nolungelelwaniso, ngokuxhomekeke kwisicelo esicetywayo.
