I-MgF2 Substrate
Incazelo
I-MgF2 isetshenziswa njengelensi, iprism kanye newindi le-wavelength ukusuka ku-110nm ukuya ku-7.5μm.Kuyinto efanelekile kakhulu njengefasitela le-ArF Excimer Laser, ngesizathu sokudluliswa kwayo okuhle ku-193nm.Isebenza futhi njenge-polarizing optical esifundeni se-ultraviolet.

Incazelo ye-MgF2 Substrate
I-MgF2 substrate isho i-substrate eyenziwe nge-magnesium fluoride (MgF2) crystal material.I-MgF2 iyinhlanganisela ye-inorganic eyakhiwa izakhi ze-magnesium (Mg) kanye ne-fluorine (F).
Ama-substrates e-MgF2 anezakhiwo ezimbalwa eziphawulekayo eziwenza adume ezinhlelweni ezihlukahlukene, ikakhulukazi emikhakheni ye-optics kanye nokubekwa kwefilimu emincane:
1. Ukukhanyela okuphezulu: I-MgF2 inokukhanyela okuhle kakhulu ku-ultraviolet (UV), ezifundeni ezibonakalayo ne-infrared (IR) ze-spectrum kagesi.Inobubanzi bokudlulisa okubanzi ukusuka ku-ultraviolet cishe ku-115 nm kuya ku-infrared cishe ku-7,500 nm.
2. Inkomba ephansi ye-refraction: I-MgF2 inenkomba ephansi uma kuqhathaniswa yokuhlehla, okuyenza ibe yinto ekahle yokuhlanganisa i-AR nama-optics, njengoba inciphisa ukubonakaliswa okungafunwa futhi ithuthukisa ukudluliswa kokukhanya.
3. Ukumuncwa okuphansi: I-MgF2 ibonisa ukumuncwa okuphansi ezindaweni ezikhanyayo ze-ultraviolet nezibonakalayo.Lesi sici sikwenza kube usizo ezinhlelweni ezidinga ukukhanya okuphezulu okukhanyayo, okufana namalensi, amaprism, namafasitela emisebeni ye-ultraviolet noma ebonakalayo.
4. Ukuzinza kwamakhemikhali: I-MgF2 iqinile kumakhemikhali, imelana nezinhlobonhlobo zamakhemikhali, futhi igcina izici zayo ezibonakalayo nezibonakalayo ngaphansi kwezimo ezihlukahlukene zemvelo.
5. Ukuzinza kwe-thermal: I-MgF2 inezinga eliphezulu lokuncibilika futhi ingakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokuwohloka okukhulu.
Ama-substrates e-MgF2 avame ukusetshenziswa kuma-optical coatings, izinqubo zokubeka ifilimu elincanyana, namafasitela abonakalayo noma amalensi kumadivayisi nezinhlelo ezihlukahlukene.Angaphinda asebenze njengezendlalelo zebhafa noma izifanekiso zokukhula kwamanye amafilimu azacile, njengezinto ze-semiconductor noma ama-metallic coatings.
Lawa ma-substrates ngokuvamile akhiqizwa kusetshenziswa amasu afana nokubeka umhwamuko noma izindlela zokuthutha umhwamuko ongokoqobo, lapho okubalulekile kwe-MgF2 kufakwa endaweni efanelekile ye-substrate noma kukhuliswe njengekristalu eyodwa.Ngokuya ngezidingo zohlelo lokusebenza, ama-substrates angaba ama-wafers, amapuleti, noma amajamo angokwezifiso.
