Inkcazo yeMgF2 Substrate
I-MgF2 substrate ibhekisa kwi-substrate eyenziwe nge-magnesium fluoride (MgF2) imathiriyeli yekristale.I-MgF2 yi-inorganic compound eyenziwe nge-magnesium (Mg) kunye ne-fluorine (F) element.
Ii-substrates ze-MgF2 zineempawu ezininzi eziphawulekayo ezizenza zidume kwizicelo ezahlukeneyo, ngakumbi kwimimandla ye-optics kunye nokubekwa kwefilimu ebhityileyo:
1. Ukucaca okuphezulu: I-MgF2 inokukhanya okubalaseleyo kwi-ultraviolet (UV), ebonakalayo kunye ne-infrared (IR) kwimimandla ye-electromagnetic spectrum.Inoluhlu olubanzi losulelo olusuka kwi-ultraviolet malunga ne-115 nm ukuya kwi-infrared malunga ne-7,500 nm.
2. Isalathisi esisezantsi se-refraction: I-MgF2 inesalathisi esincinci se-refraction, esenza ukuba ibe yinto efanelekileyo yeengubo ze-AR kunye ne-optics, njengoko inciphisa ukubonakaliswa okungafunekiyo kunye nokuphucula ukuhanjiswa kokukhanya.
3. Ukufunxa okuphantsi: I-MgF2 ibonisa ukuxutywa okuphantsi kwi-ultraviolet kunye nemimandla ebonakalayo ebonakalayo.Le propati yenza kube luncedo kwizicelo ezifuna ukucaca okuphezulu kwe-optical, njengeelensi, iiprism, kunye neefestile ze-ultraviolet okanye iiplanga ezibonakalayo.
4. Ukuzinza kweekhemikhali: I-MgF2 iqinile kwiikhemikhali, ixhathisa uluhlu olubanzi lweekhemikhali, kwaye igcina iimpawu zayo ezibonakalayo kunye nezakhiwo phantsi kweemeko ezininzi zokusingqongileyo.
5. Ukuzinza kwe-Thermal: I-MgF2 inendawo ephezulu yokunyibilika kwaye inokumelana namaqondo okushisa aphezulu ngaphandle kokuthotywa okukhulu.
Ii-substrates ze-MgF2 ziqhele ukusetyenziswa kwi-optical coatings, kwiinkqubo zokubeka ifilimu ecekethekileyo, kunye neefestile zamehlo okanye iilensi kwizixhobo ezahlukeneyo kunye neenkqubo.Zisenokusebenza njenge-buffer layers okanye iitemplates zokukhula kwezinye iifilimu ezibhityileyo, ezifana nemathiriyeli ye-semiconductor okanye i-metallic coatings.
Ezi substrates ngokuqhelekileyo ziveliswa kusetyenziswa ubuchule obufana nokubeka umphunga okanye iindlela zokuthutha umphunga womzimba, apho iMgF2 imathiriyeli ifakwe kwi-substrate imathiriyeli efanelekileyo okanye ikhule njengekristale enye.Ngokuxhomekeke kwiimfuno zesicelo, i-substrates ingaba ngohlobo lwee-wafers, iipleyiti, okanye iimilo eziqhelekileyo.
