Izinto ezifunxayo ezikufuphi ne-infrared zidibanisa ukukhanya okuphezulu okubonakalayo kunye nokufunxa okuqinileyo okukhethiweyo ngokuchasene nokukhanya kwe-infrared.Ngokomzekelo, ngokuyisebenzisa kwizinto zefestile, amandla emitha ye-infrared ekufutshane equlethwe ekukhanyeni kwelanga anqunywe ngokufanelekileyo ngelixa egcina ukukhanya okwaneleyo, okubangelwa umphumo othintela kakhulu ukunyuka kweqondo lokushisa kwigumbi.

Ukukhanya kwelanga kuqulethe imitha ye-ultraviolet (UVC: ~290 nm, UVB:290 ukuya ku-320 nm, UVA:320 ukuya ku-380 nm), imitha ebonakalayo (380 ukuya ku-780 nm), kufuphi nemitha ye-infrared (780 ukuya ku-2500 nm), kunye ne-infrared ephakathi imitha (2500 ukuya 4000 nm).Umlinganiselo wayo wamandla yi-7% kwimitha ye-ultraviolet, i-47% yemitha ebonakalayo, kunye ne-46% kwimitha ye-infrared ekufutshane kunye nephakathi.Imitha ekufuphi ne-infrared (emva koku ishunqulelwe njenge-NIR) inobunzulu obuphezulu bemitha kumaza amafutshane, kwaye ingena eluswini kwaye ibe nefuthe eliphezulu lokuvelisa ubushushu, ke ikwabizwa ngokuba "yimitha yobushushu."

Iglasi efunxa ubushushu okanye iglasi ebonisa ubushushu ngokuqhelekileyo isetyenziselwa ukukhusela iglasi yefestile kwimitha yelanga.Iglasi efunxa ubushushu yenziwa yi-NIR-absorption ye-iron (Fe) components, njl.njl ixovwe kwiglasi, kwaye inokuveliswa ngokungabizi.Nangona kunjalo, ukukhanya okubonakalayo okubonakalayo akunakuqinisekiswa ngokwaneleyo kuba kunombala wethoni ekhethekileyo kwizinto eziphathekayo.Iglasi ebonakalisa ubushushu, kwelinye icala, izama ukubonakalisa amandla emitha yelanga ngokwenza ngokwasemzimbeni isinyithi kunye neeoksidi zetsimbi kumphezulu weglasi.Nangona kunjalo, amaza amaza abonakalisiweyo adlulela ekukhanyeni okubonakalayo, okubangela ilitha kwinkangeleko kunye nokuphazamiseka koonomathotholo.Ukusasazwa kwee-conductor ezicacileyo ezifana ne-high-performance-high-shielding ITOs kunye nee-ATO ezinokukhanya okuphezulu okubonakalayo okubonakalayo kwaye akukho kuphazamiseka kwamaza erediyo kwiikhemikhali ze-nano-fine kuvelisa iprofayili ecacileyo njengoko kubonisiwe kwi-Fig. amaza elubala.

Isiphumo somthunzi wokukhanya kwelanga sibonakaliswa ngokobungakanani ngokwezinga lokufumana ubushushu bemitha yelanga (iqhezu lamandla okukhanya kwelanga ahamba ngeglasi) okanye into ekhusela kwimitha yelanga eyenziwe yesiqhelo ngeglasi ecacileyo eyi-3 mm.
