Idirishya rya safiro Kubushyuhe bwo hejuru
Mugihe cyo gukoresha itanura ryinganda nicyumba cya vacuum, idirishya ryerekanwa rizaterwa numuvuduko mwinshi nubushyuhe bwo hejuru.Kugirango umenye umutekano wabashakashatsi, idirishya ryerekanwa rigomba gucanwa, ryizewe, ryihanganira ubushyuhe bwo hejuru, naryo rifite ibyiza bya optique.Sintetike ya safiro nibikoresho byiza nkidirishya ryo kureba.
Safiro ifite ibyiza byingutu zayo: irashobora kwihanganira umuvuduko mbere yo guturika.Safiro ifite imbaraga zingutu zigera kuri 2 GPa.Ibinyuranye, ibyuma bifite ingufu za MPa 250 (hafi inshuro 8 munsi ya safiro) naho ikirahuri cyingagi (™) gifite ingufu za 900 MPa (munsi ya kimwe cya kabiri cya safiro).Hagati aho, safiro, ifite imiti myiza yimiti kandi yinjizwamo imiti hafi ya yose, bigatuma ibera aho ibikoresho byangirika bihari.Ifite ubushyuhe buke cyane, 25 W m '(- 1) K ^ (- 1), hamwe na coeffisente yo kwaguka cyane ya 5.8 × 10 ^ 6 / C: nta guhindura cyangwa kwaguka kwimiterere yubushyuhe hejuru cyangwa hejuru ubushyuhe.Igishushanyo cyawe cyose, urashobora kwemeza neza ko gifite ubunini nubwihangane kuri metero 100 munsi yinyanja cyangwa 40K muri orbit.
Twakoresheje ibi biranga imbaraga hamwe na windows idashobora kwihanganira mugukoresha abakiriya, harimo ibyumba bya vacuum hamwe nitanura ryubushyuhe bwo hejuru.
Idirishya rya safiro ku itanura rifite ubwiza buhebuje mu ntera ya 300nm kugeza 5500nm (ikubiyemo ultraviolet, ahantu hagaragara na infragre) kandi ikagera ku gipimo cyo kwanduza hafi 90% kuri 300 nm kugeza kuri 500 nm.Safiro ni ibintu byikubye kabiri, kubwinshi muburyo bwa optique bizaterwa nicyerekezo cya kristu.Ku murongo wacyo usanzwe, indangagaciro zayo ziva kuri 1.796 kuri 350nm kugeza kuri 1.761 kuri 750nm, kandi niyo ubushyuhe bwahinduka cyane, burahinduka bike cyane.Bitewe numuyoboro mwiza wogukwirakwiza hamwe nuburebure bwumurambararo mugari, dukoresha idirishya rya safiro mugushushanya kwa lens infrared lens mu ziko mugihe ibirahuri bisanzwe bidakwiriye.
Hano hari Inararibonye yo Kubara Ubunini bwa idirishya rya safiro:
Th = √ (1.1 x P x r² x SF / MR)
aho:
Th = Ubunini bwidirishya (mm)
P = Igishushanyo cyo gukoresha igitutu (PSI),
r = Iradiyo idashyigikiwe (mm),
SF = Impamvu z'umutekano (4 kugeza 6) (urwego rusabwa, rushobora gukoresha izindi mpamvu),
MR = Modulus yo guturika (PSI).Safiro nka 65000PSI
Kurugero, idirishya rya safiro rifite diameter 100 mm na radiyo idashyigikiwe na mm 45 ikoreshwa mubidukikije hamwe na Pressure itandukanya ikirere 5 igomba kuba ifite uburebure bwa ~ 3.5mm (ibintu byumutekano 5).
