Ultra High Vacuum Sapphire Viewport
Sapphire ndeimwe yezvakaomesesa optical zvinhu mumainjiniya maapplication.Iyo transparent monocrystalline alumina (Al2O3) sapphire inopawo yepamusoro yekupisa michina zvivakwa zvichienzaniswa neanenge ese mamwe mahwindo emidziyo anoshandiswa muHV/UHV kugadzirisa.
Iyo yekutsikirira simba inosvika mazana maviri eMPa uye simba rekukotama rinosvika mazana mana eMPa ndiwo akajairwa emuchina zvivakwa zvesafire.Maonero eSapphire anozivikanwa kuve akaomarara uye anotora mukana weiyo yakanakisa Yang's modulus (-350 GPa), iyo inobatsira kuve nechokwadi chekuti kushushikana kwekushushikana kwendiro yegirazi kwakanakira kushanda mukumanikidzwa kwetrillionth yekuraira kwehukuru hwe. kumanikidzwa kwemhepo.
Kune yakakwira tembiricha vacuum kurapwa maapplication, safire viewports akakodzerawo.Zvishandiso zvakadaro zvinogona kusanganisira physical vapor deposition (PVD).Iyo pani yakaratidza kuti inomira yakavimbika kuenderera kunoshanda tembiricha muhuwandu hwe400 madhigirii C (752 degrees C), kunyangwe uyu muganho wakaganhurirwa kune chimiro chekamuri.Safire chete inokwanisa kumira tembiricha inosvika 1800 degrees C (3272 degrees F).
Zvakangodaro, kune akawanda mamwe maitiro ekuona zvinhu anogona kushandiswa mumashandisirwo senge kumanikidzwa uye kupisa kurapwa.Kubatsira kukuru kwesafire pamusoro pemamwe marudzi emahwindo ndeyekuti zvinhu zvine yakanakisa kutapurirana kwechiedza.
Pamasaisai emwenje ari pakati pe150 ne5500 nanometers (nm), sapphire viewport inoonekera zvakanyanya, inotambanudzira nhamba huru yeultraviolet (UV) uye inooneka spectra, uye inotambanudzirwa zvakanakisa kusvika pedyo-infrared (IR) siyana.Ita shuwa kutariswa kwakaringana kweHV/UHV kugadzirisa mamiriro pasina kudiwa kwekuwedzera kwekupfeka kwepamusoro.
Sapphire's isingaenzaniswi mechanicha zvimiro ndiyo kiyi yekuwana iyi yakanakisa kutapurirana mhando, sezvo kuderera kwepasi kupera kunogona kukanganisa zvakanyanya kutapurirana kwewavelength, kunyanya kupfupi-wave radiation.
Sapphire ndiyo yechitatu yakaomesesa zvinhu zveinjiniya papasi redu, ichivimbisa zvinoshamisa kukwenya kuramba uye kupfeka kuramba.Nekuda kwekuoma uku, nzvimbo yekuona yesafire inochengetedza zvivakwa zvekutumira-kumashure kwekushandisa kwenguva refu munzvimbo dzakaomarara dzekugadzirisa.
