Amadirishya ya Sapphire Optical yihariye yo kohereza urumuri rwinshi ≥90%

Ibisobanuro bigufi:

Amadirishya ya safiro ni ibikoresho byihariye bya optique byakozwe muri oxyde ya aluminiyumu imwe (Al₂O₃), izwiho imikorere yayo idasanzwe ya optique, imbaraga za mekanike, no kudahindagurika kwa shimi. Nk'amadirishya ya safiro akomeye cyane (ubukana bwa Mohs 9), agaragaza ubushobozi bwo kohereza neza (~83-85% adatwikiriye) kuri ultraviolet (200nm) kugeza kuri mid-infrared (5.5μm), bigatuma aba meza cyane mu gukoresha ibintu byinshi bisaba ubwisanzure no kuramba.

Gukora bikubiyemo inzira z'ingenzi zirimo gukura mu buryo bwa kristu, gukata neza, gusiga nanoscale polishing, no gusiga irangi ryihariye. Uburyo bugezweho bwo gukura (urugero, uburyo bwa HEM cyangwa KY) butanga imipira myiza ifite ubucucike buke (<10⁴/cm²). Imiterere yihariye ya kristu ifite impande esheshatu ituma imiterere ya anisotropic, hamwe n'imiterere myiza (C-axis, A-axis, cyangwa R-plane cuts) ihindura imikorere y'urumuri ku bikorwa byihariye.

Ibiranga by'ingenzi

1. Guhangana n'ibidukikije bikabije
Amadirishya ya safiro agaragaza imikorere idasanzwe hamwe n’ikigero cyo gushonga cya 2053°C, agakomeza ubuziranenge bw’imiterere mu bidukikije bihora bikoresha ubushyuhe bwa 1000°C. Uku guhagarara k’ubushyuhe gushyigikiwe n’ikigereranyo cyo hasi cyane cy’ubushyuhe (CTE) cya 5.3×10⁻⁶/K ku murongo wa C, kurusha cyane indorerwamo zisanzwe z’ubushyuhe. Mu rwego rwa shimi, amadirishya ya safiro agaragaza ubudahangarwa butangaje, arwanya aside ikomeye yose (usibye HF) na alkali, bigatuma aba meza mu bikoresho bitunganya imiti no mu mazi. Mu rwego rwa mashini, aya madirishya afite imbaraga zo kuzunguruka zirenga 1000MPa (inshuro 5-8 z’indorerwamo zisanzwe z’ubushyuhe) kandi arwanya cyane ingaruka.

2. Ibyiza by'imikorere y'urumuri
Amadirishya ya Safiro atanga ubushobozi bwo kohereza amakuru ku gipimo cyagutse (200-5500nm ku bunini bwa mm 2). Binyuze mu cyerekezo cyiza cya kristale (urugero, C-axis perpendicular under the light pathway), ingaruka za birefringence ziragabanuka cyane. Ubwiza bw'ubuso bwujuje ibisabwa bikomeye by'urumuri hamwe na λ/10 flatness kuri 633nm n'ubugari bw'ubuso <0.5nm RMS.

3. Ubushobozi bwo gukora ibintu buhanitse
Amadirishya yacu ya safiro ashyigikira uburyo bunini bwo gutunganya (>300mm diameter) n'imiterere y'ijimetero igoye harimo imiterere ya aspheric n'intambwe. Ikoranabuhanga ryihariye ryo gufunga impande rituma habaho igipimo cyo kuva amazi <1×10⁻⁹Pa·m³/s mu gukoresha vacuum. Hamwe n'imyambaro isa na diyama (DLC), urwego rwa laser-induced damage threshold (LIDT) rugera kuri 15J/cm² (1064nm, 10ns pulses).

Porogaramu z'ibanze

1. Ubwunganizi n'Ibyerekeye Ikiremba
Amadirishya y’urumuri rwa safiro akora nk’ibisasu bya misile, yihanganira ubushyuhe bukabije (>1000°C) mu gihe cyo kuguruka mu kirere. Ibyuma byo mu kirere byemeza ko bizamara imyaka 15 mu kirere mu bikorwa byo mu kirere.

2. Ibikoresho by'inganda
Mu gukora semiconductor, amadirishya ya safiro akora nk'ahantu ho kureba ibintu bidapfa kwangirika mu byumba bya etch na CVD. Endoscopes z'ubushyuhe bwinshi zikoresha aya madirishya mu gufata amashusho meza mu bidukikije by'ifuru ya 1500°C.

3. Ibikoresho bya siyansi
Amadirishya ya safiro afite isuku nyinshi (<5ppm imyanda) agabanya kwinjiza X-ray mu mirasire ya synchrotron. Ubudahangarwa bwayo buke butuma impumuro ya femtosecond ikomeza kuba nziza muri sisitemu ya laser yihuta cyane.

4. Ibikoresho by'ubucuruzi
Ibikoresho byo mu mazi y’inyanja byimbitse bikoresha amadirishya ya safiro afite ubujyakuzimu bwa metero 6000 (>60MPa). Kamera za telefoni zigendanwa zihuza aya madirishya nk'ibifuniko birinda, zikoresha uburyo bwa Mohs 9 bwo kurwanya gushwanyagurika kugira ngo birusheho gukomera.

Amadirishya ya Safira akomeje kwagura ikoreshwa ryayo binyuze mu iterambere mu gutunganya ibintu binini, ubuhanga buhambaye, no kunoza imikorere, bikomeza umwanya wayo nk'ibintu by'ingenzi mu nganda zikora ikoranabuhanga rigezweho.

Serivisi za XKH

Urubuga rwa serivisi rwa XKH ruhuza ubuhanga buhanitse mu gukora ibikoresho hamwe n'ubufasha bukomeye bwa tekiniki kugira ngo rutange ibisubizo by'amadirishya ya safiro agezweho. Ishami rikora ibikoresho byihariye ritanga uburyo bwo gutunganya ibikoresho hifashishijwe ikoranabuhanga rya 2D/3D, ryunganirwa na serivisi zo gutunganya ibikoresho (DFM) zigabanya ibyago n'ikiguzi cy'umusaruro. Dufite ubushobozi bwo gukora porogaramu zihuse mu nganda, dutanga ingero za Φ100mm mu minsi 5 y'akazi kugira ngo twihutishe imigendekere y'ibikorwa by'umusaruro. Uburyo bugezweho bwo gukora ibikoresho burimo gutwikira neza ibikoresho bifite ubushobozi bwo kwirinda ibyuma kuva kuri 10-1000Ω/□ kugira ngo bikoreshwe mu kurinda EMI, hamwe na filime zirwanya ibihu zigumana ubwiza bw'urumuri ahantu hari ubushuhe bwinshi.

Ibikorwa remezo by’ubufasha mu bya tekiniki bifite itsinda ryihariye ry’abahanga bakoresha porogaramu ya Zemax na CodeV optical simulation kugira ngo bagaragaze imikorere ya sisitemu no guhanura imikorere y’ubushyuhe/mekanike mu bihe by’imikorere. Laboratwari yacu yo gusuzuma ibikoresho, ifite microscopy ya electron scanning (SEM) na energy-dispersive X-ray spectroscopy (EDS), itanga isesengura ry’impamvu y’impinduka mu miterere kugira ngo irusheho kuba nziza. Serivisi zo kugenzura ibidukikije zirimo ibizamini by’ubushyuhe bukabije (-196℃ kugeza 800℃) n’ishyirwa mu gihe cy’amasaha 500 hakurikijwe ibipimo bya MIL-STD-810G, bigamije kwemeza ko ibice biramba mu bihe bikomeye by’imikorere.

Sisitemu zo kugenzura ubuziranenge zikoresha uburyo bwose bwo gukurikirana ibintu kuva kuri kristale boule kugeza ku gicuruzwa cyarangiye, buri gice kiherekejwe n'inyandiko yuzuye y'ubuziranenge. Ubushobozi bugezweho bwo gupima burimo interferometry ya 4D phase-shifting kugira ngo harebwe neza ubuziranenge bw'ubuso bwa λ/50, interferometry y'urumuri rwera igera ku gipimo cya 0.1nm cy'ubuso bugoye, hamwe n'isesengura rya spectrophotometric rikubiyemo uburebure bwa 190-3300nm bwa spectral kugira ngo harebwe uburyo bwo kohereza no gusubiza urumuri.

Serivisi zongerewe agaciro zireba ibisabwa byihariye mu gukoresha, harimo n'ibisubizo byo guhuza imashini zikoresha icyuma hamwe n'icyuma gikingira umwuka gikoresheje icyuma gikoresha icyuma gikoresha icyuma gikoresha icyuma gikoresha icyuma gikoresha icyuma gikoresha icyuma gikoresha icyuma gikoresha icyuma gikoresha amashanyarazi (UHV). Serivisi zo kugenzura ikoreshwa ry'amashanyarazi (ESD) zigena uburyo bwo kwirinda ubushyuhe buri hagati ya 10⁶-10⁹Ω kugira ngo hirindwe ko umuriro wiyongera mu bikoresho byoroheje. Ibice byose bishyirwa mu ipaki rya nyuma mu byumba byo mu rwego rwa 100, hamwe n'uburyo bwo kubara ibice by'icyuma no gupakira imashini zikoresha icyuma gikoresha icyuma gikoresha amashanyarazi kugira ngo habeho isuku ijyanye n'urwego rw'isuku.
