Ultra High Vacuum Sapphire Viewport
Sapphire yog ib qho ntawm cov khoom siv kho qhov muag nyuaj tshaj plaws hauv kev siv engineering.Cov pob tshab monocrystalline alumina (Al2O3) sapphire kuj muaj cov khoom siv thermal zoo dua piv rau yuav luag tag nrho lwm cov ntaub ntawv qhov rais siv hauv HV / UHV ua.
Lub zog compression ntawm kwv yees li 2000 MPa thiab khoov lub zog txog li 400 MPa yog cov khoom siv zoo ntawm sapphires.Sapphire viewpoints paub tias yuav nyuaj heev thiab coj kom zoo dua ntawm cov khoom zoo heev Yang's modulus (-350 GPa), uas yuav pab xyuas kom meej tias qhov kev ntxhov siab strain piv ntawm iav phaj yog zoo tagnrho rau kev khiav hauj lwm ntawm pressures ntawm ib trillionth ntawm qhov kev txiav txim ntawm magnitude. atmospheric siab.
Rau kev siv lub tshuab nqus tsev kub kub, sapphire viewports kuj tsim nyog.Cov ntawv thov no tuaj yeem suav nrog lub cev vapor deposition (PVD).Lub pane tau raug pov thawj kom ntseeg tau tias muaj kev tiv thaiv kev ua haujlwm tsis tu ncua ntawm qhov kub ntawm 400 ° C (752 ° C), txawm hais tias qhov kev txwv no txwv rau cov qauv chamber.Sapphire ib leeg tuaj yeem tiv taus qhov kub txog li 1800 ° C (3272 ° F).
Txawm li cas los xij, muaj ntau ntau lwm cov ntaub ntawv saib uas tuaj yeem ua haujlwm hauv cov ntawv thov xws li kev kub siab thiab kev kho cua sov.Lub ntsiab kom zoo dua ntawm sapphire tshaj lwm hom qhov rais yog tias cov khoom muaj lub teeb kis tau zoo heev.
Rau lub teeb wavelengths ntawm 150 thiab 5500 nanometers (nm), sapphire viewport yog heev pob tshab, spans ib tug loj tus naj npawb ntawm ultraviolet (UV) thiab pom spectra, thiab yog zoo heev txuas mus rau ze-infrared (IR) ranges.Ua kom pom kev pom zoo ntawm HV / UHV kev ua haujlwm yam tsis tas yuav tsum muaj txheej txheej ntxiv.
Sapphire's unparalleled mechanical zog yog qhov tseem ceeb rau kev ua tiav qhov kev sib kis tau zoo, vim qhov ua tiav tsis zoo tuaj yeem cuam tshuam rau kev sib kis wavelength, tshwj xeeb tshaj yog rau cov hluav taws xob luv luv.
Sapphire yog qhov thib peb cov khoom siv hluav taws xob nyuaj tshaj plaws hauv peb lub ntiaj teb, kom ntseeg tau tias khawb tsis txaus ntseeg thiab hnav tsis kam.Vim qhov hardness no, sapphire viewport tswj nws cov khoom xa tawm tom qab kev teeb tsa rau kev siv mus sij hawm ntev hauv kev ua haujlwm hnyav.
