Sapphire Windows – ezigbo njirimara mbufe ngwa anya
Nkọwa ngwaahịa
A na-eji sapphire dị ka ntuziaka ọkụ maka immersion infrared spectroscopy yana kwa maka Er: YAG nnyefe laser na 2.94 µm. Sapphire nwere ezigbo ike nke elu na nnyefe na-esi na ultraviolet ruo n'etiti etiti infrared wavelength mpaghara. Enwere ike ịcha sapphire naanị site na obere ihe ndị ọzọ karịa onwe ya. Ihe ndị na-enweghị mkpuchi bụ kemịkalụ na-adịghị adị na mmiri, acids nkịtị ma ọ bụ ntọala ruo ihe dịka 1000 ° C. Window sapphire anyị nwere akụkụ z nke mere na c-axis nke kristal dabara na axis anya, na-ewepụ mmetụta birefringence na ọkụ na-ebufe.
Sapphire dị dị ka mkpuchi ma ọ bụ nke a na-ekpuchighị ya, a na-emepụta ụdị ahụ na-enweghị mkpuchi maka ngwa dị na 150 nm - 4.5 µm, ebe AR mkpuchi nke nwere mkpuchi AR n'akụkụ abụọ bụ maka 1.65 µm - 3.0 µm (-D) ma ọ bụ 2.0 µm. - 5.0 μm (-E1) oke.
Window (Windows) Otu n'ime akụrụngwa ngwa anya dị na ngwa anya, nke a na-ejikarị dị ka windo nchebe maka sensọ eletrọnịkị ma ọ bụ ihe nchọpụta nke gburugburu mpụta. Sapphire nwere ezigbo ihe eji arụ ọrụ na ngwa anya, yana kristal sapphire ejirila ọtụtụ ebe. Ihe eji eme ya gụnyere ihe ndị na-adịghị eyi uwe, ihe windo, yana MOCVD epitaxial substrate ihe, wdg.
Mpaghara ngwa
A na-eji ya na foto dị iche iche na spectrometers, a na-ejikwa ya na ọkụ mmeghachi omume na ọkụ ọkụ dị elu, windo sapphire na-ahụ maka ngwaahịa dị ka reactors, lasers na ụlọ ọrụ.
Ụlọ ọrụ anyị nwere ike ịnye windo okirikiri sapphire na ogologo 2-300mm na ọkpụrụkpụ nke 0.12-60mm (nke ziri ezi nwere ike iru 20-10, 1/10L @ 633nm).
