MgF2 Substrate
Ibisobanuro
MgF2 ikoreshwa nka lens, prism hamwe nidirishya ryuburebure kuva 110nm kugeza 7.5 mm.Nibikoresho byiza cyane nkidirishya rya ArF Excimer Laser, kubwimpamvu yo kohereza neza kuri 193nm.Ifite kandi akamaro nka optique ya polarisike mukarere ka ultraviolet.

Ibisobanuro bya MgF2
MgF2 substrate bivuga substrate ikozwe muri fluoride ya magnesium (MgF2).MgF2 ni organic organique igizwe na magnesium (Mg) na fluor (F).
MgF2 substrates ifite imitungo myinshi igaragara ituma bakundwa mubikorwa bitandukanye, cyane cyane mubice bya optique no kubika firime yoroheje:
1. Gukorera mu mucyo mwinshi: MgF2 ifite umucyo mwiza muri ultraviolet (UV), igaragara kandi itagaragara (IR) mukarere ka electromagnetic.Ifite imiyoboro yagutse kuva ultraviolet kuri 115 nm kugeza kuri infragre kuri 7.500 nm.
2. Indanganturo yo kugabanuka: MgF2 ifite igipimo gito cyo kugabanuka, bigatuma iba ibikoresho byiza bya AR bitwikiriye na optique, kuko bigabanya ibitekerezo bidakenewe kandi bigateza imbere urumuri.
3. Kwinjiza gake: MgF2 yerekana kwinjirira muke muri ultraviolet no mubice bigaragara.Uyu mutungo utuma ugira akamaro mubisabwa bisaba optique isobanutse neza, nka lens, prism, na windows ya ultraviolet cyangwa ibiti bigaragara.
4. Ihungabana ryimiti: MgF2 ihagaze neza mumiti, irwanya imiti myinshi, kandi ikomeza imiterere ya optique na physique mugihe cyibidukikije byinshi.
5. Ubushyuhe bwumuriro: MgF2 ifite aho ishonga cyane kandi irashobora kwihanganira ubushyuhe bwinshi bwakazi nta kwangirika gukomeye.
MgF2 substrates isanzwe ikoreshwa muburyo bwa optique, uburyo bwo kubika firime yoroheje, hamwe na windows ya optique cyangwa lens mubikoresho na sisitemu zitandukanye.Barashobora kandi gukora nka buffer layer cyangwa inyandikorugero zo gukura kwizindi firime zoroheje, nkibikoresho bya semiconductor cyangwa metallic coatings.
Ubusanzwe insimburangingo ikorwa hifashishijwe tekinoroji nko kubika imyuka cyangwa uburyo bwo gutwara imyuka yumubiri, aho ibikoresho bya MgF2 bishyirwa mubintu bikwiye cyangwa bigakura nka kristu imwe.Ukurikije ibisabwa bisabwa, substrate irashobora kuba muburyo bwa wafer, amasahani, cyangwa imiterere yihariye.
