Qeexida Substrate MgF2
Substrate MgF2 waxa loola jeedaa substrate ka samaysan magnesium fluoride (MgF2) walxo crystal ah.MgF2 waa unug aan organic ahayn oo ka kooban magnesium (Mg) iyo fluorine (F).
Substrates MgF2 waxay leeyihiin dhowr siyaalood oo caan ah oo ka dhigaya kuwo caan ku ah codsiyo kala duwan, gaar ahaan dhinacyada optics iyo dhigista filimada khafiifka ah:
1. Daah-furnaan sare: MgF2 waxay leedahay daahfurnaan heer sare ah oo ku jirta ultraviolet (UV), muuqata iyo infrared (IR) ee spectrum electromagnetic.Waxay leedahay faafin ballaaran oo u dhexeeya ultraviolet qiyaastii 115 nm ilaa infrared qiyaastii 7,500 nm.
2. Tusmada hoose ee dib-u-soo-celinta: MgF2 waxay leedahay tusaha dib-u-celinta oo yara hooseeya, taas oo ka dhigaysa wax ku habboon daboolka AR iyo muraayadaha, maaddaama ay yareyso milicsiga aan loo baahnayn oo ay wanaajiso gudbinta iftiinka.
3. Nuugista hoose: MgF2 waxay muujinaysaa nuugista hoose ee ultraviolet iyo gobollada muuqaalka muuqda.Gurigan wuxuu ka dhigayaa mid faa'iido u leh codsiyada u baahan caddaynta sare ee indhaha, sida muraayadaha, muraayadaha, iyo daaqadaha ultraviolet ama laydhka muuqda.
4. Degganaanshaha kiimikaad: MgF2 kiimikaad ahaan waa u xasilloon, adkaysi u leh kiimikooyin badan oo kala duwan, waxayna ilaalinaysaa astaamaheeda muuqaal iyo muuqaal iyada oo ay ku jiraan xaalado kala duwan oo deegaanka ah.
5. Deganaanshiyaha kulaylka: MgF2 waxay leedahay meel dhalaalaysa oo heerkulkeedu sarreeyo waxayna u adkeysan kartaa heerkulka shaqada sare iyada oo aan hoos u dhicin.
Substrate-ka MgF2 waxaa sida caadiga ah loo isticmaalaa daahan indhaha, hababka dhigista filimada khafiifka ah, iyo muraayadaha indhaha ama muraayadaha ee qalabka iyo nidaamyada kala duwan.Waxay sidoo kale u adeegi karaan lakabyo daboolaya ama qaabab loogu talagalay koritaanka filimada kale ee khafiifka ah, sida qalabka semiconductor ama daahan macdan ah.
Qaybahaan waxaa sida caadiga ah lagu soo saaraa farsamooyin ay ka mid yihiin dhigista uumiga ama hababka gaadiidka uumiga jirka, halkaasoo walxaha MgF2 lagu shubo walxo substrate ku habboon ama loo koray sidii hal crystal.Iyada oo ku xidhan shuruudaha codsiga, substrate-yadu waxay noqon karaan qaab wafers, saxanno, ama qaabab gaar ah.
