I-Short-Wave Infrared (SWIR) yenza ilensi yokukhanya eyenzelwe ukuba ibambe isibane esifutshane se-infrared esingenakubonwa ngokuthe ngqo ngeliso lomntu. Eli bhanti ngokuqhelekileyo lichongwe njengokukhanya kunye nobude be-wavelengths ukusuka kwi-0.9 ukuya kwi-1.7 microns. Umgaqo wokusebenza welensi ye-infrared emfutshane ixhomekeke kwiipropathi zothumelo lwesixhobo sobude obuthile bokukhanya, kwaye ngoncedo lwemathiriyeli ekhethekileyo ye-optical kunye netekhnoloji yokwaleka, ilens inokuqhuba ngobuchule ukukhanya okufutshane kwamaza e-infrared ngelixa icinezela okubonakalayo. ukukhanya kunye namanye amaza amaza angafunekiyo.
Iimpawu zayo eziphambili ziquka:
1. Ukuhanjiswa okuphezulu kunye nokukhetha okubonakalayo:Iilensi ze-SWIR zisebenzisa izixhobo ezikhethekileyo zokukhanya kunye netekhnoloji yokugquma ukuze ufumane ukuhanjiswa okuphezulu ngaphakathi kwebhendi ye-infrared ye-infrared (i-0.9 ukuya kwi-1.7 microns) kwaye ibe nokukhetha okubonakalayo, iququzelele ukuchongwa kunye nokuqhutywa kobude obuthile bokukhanya kwe-infrared kunye nokuthintelwa kobunye ubude bamaza okukhanya. .
2. Ukunganyangeki kwe-Chemical corrosion kunye nokuzinza kwe-thermal:Izinto eziphathekayo kunye nokugquma kwelensi kubonisa ukuzinza okugqwesileyo kweekhemikhali kunye ne-thermal kwaye kunokugcina ukusebenza kwe-optical phantsi kokuguquguquka okukhulu kobushushu kunye neemeko ezahlukeneyo zokusingqongileyo.
3. Isisombululo esiphezulu kunye nokuphazamiseka okuphantsi:Iilensi ze-SWIR zibonakalisa ukusonjululwa okuphezulu, ukugqwetheka okuphantsi, kunye neempawu zokuphendula ngokukhawuleza, ezizalisekisa iimfuno zenkcazo ephezulu.
Iilensi ze-infrared ezimfutshane zisetyenziswa kakhulu kwindawo yokuhlola ishishini. Umzekelo, kwinkqubo yokwenziwa kwe-semiconductor, iilensi ze-SWIR zinokubona iimpazamo ngaphakathi kwee-silicon wafers ekunzima ukuzibona phantsi kokukhanya okubonakalayo. Itekhnoloji ye-infrared imaging ye-Shortwave inokwandisa ukuchaneka kunye nokusebenza kakuhle kokuhlolwa kwe-wafer, ngaloo ndlela inciphisa iindleko zokwenziwa kunye nokuphucula umgangatho wemveliso.
Iilensi ze-infrared zamaza amafutshane zidlala indima ebalulekileyo ekuhlolweni kwe-wafer ye-semiconductor. Kuba ukukhanya okufutshane kwe-infrared kunokungena kwi-silicon, olu phawu luxhobisa iilensi ze-infrared ezifutshane ukuze zibone iziphene ngaphakathi kweewafers zesilicon. Ngokomzekelo, i-wafer ingaba ne-fissures ngenxa yoxinzelelo olushiyekileyo ngexesha lenkqubo yokuvelisa, kwaye ezi zintlukwano, ukuba azibonakali, ziya kuba nefuthe ngokuthe ngqo kwimveliso kunye neendleko zokuvelisa ze-IC chip yokugqibela. Ngokusebenzisa iilensi ze-infrared zamaza amafutshane, ezo ziphene zinokuqondwa ngokufanelekileyo, ngaloo ndlela zikhuthaza ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.
Kusetyenziso olusebenzayo, iilensi ze-infrared zamaza amafutshane zinokubonelela ngemifanekiso echasa kakhulu, yenze ukuba neziphene ezimfutshane zibonakale ngokucacileyo. Ukusetyenziswa kobu buchwepheshe bokubona akugcini nje ukwandisa ukuchaneka kokuchongwa kodwa kunciphisa iindleko kunye nexesha lokukhangela ngesandla. Ngokwengxelo yophando lwemakethi, imfuno yeelensi ze-infrared ezifutshane kwimakethi yokufumanisa i-semiconductor inyuka unyaka nonyaka kwaye kulindeleke ukuba igcine indlela yokukhula ezinzileyo kwiminyaka embalwa ezayo.
