Musiyano uripo pakatigirazi remazisouye mamwe magirazi ndeekuti sechikamu chehurongwa hwemaziso, chinofanira kusangana nezvinodiwa zvemifananidzo yemaziso.
Tekinoroji yayo yekugadzirisa inotonhora inoshandisa mushonga wekupisa nemakemikari uye chidimbu chimwe chete chegirazi resilica resoda-lime kuti ichinje chimiro chayo chepakutanga chemorekuru pasina kukanganisa ruvara rwepakutanga uye kufambiswa kwechiedza kwegirazi, zvichiita kuti risvike padanho rekuomarara zvakanyanya, uye rinosangana nezvinodiwa zvekudzivirira moto pasi pekupisa kwakanyanya kwemurazvo. Girazi rakasimba kwazvo rinodzivirira moto uye nzira yaro yekugadzira uye michina yakakosha. Yakagadzirwa nezvinhu zvinotevera: potassium salt vapor (72% ～ 83%), argon (7% ～ 10%), gaseous copper chloride (8% ～ 12%), nitrogen (2 % ～ 6%).
Hunhu hwegirazi re optical hune zvinodiwa zvinotevera:
1. Zvimisikidzo zve optical zvakananga uye kuenderana kwezvimisikidzo zve optical zveboka rimwe chete regirazi
Rudzi rumwe nerumwe rwegirazi reoptical rine chiyero chakatarwa che refractive index value chema wavelength akasiyana echiedza, icho chinoshanda sehwaro hwevagadziri veoptical kugadzira masisitimu eoptical. Zvimisikidzo zveoptical zvegirazi rese reoptical rinogadzirwa mufekitori zvinofanirwa kunge zviri mukati mehuwandu hwakati hwezviyero izvi, zvikasadaro mhando chaiyo yemifananidzo haizoenderane nemhedzisiro inotarisirwa panguva yekugadzira uye mhando yemudziyo weoptical ichakanganiswa.
2. Kujeka Kwakanyanya
Kupenya kwemufananidzo we optical system kunoenderana nekujeka kwegirazi. Kujeka kwegirazi re optical kuchiedza che wavelength yakati kunoratidzwa ne light absorption coefficient Kλ. Mushure mekunge chiedza chapfuura nepakati pe prisms nema lenses, chikamu chesimba racho chinorasika ne interface reflection yezvikamu zve optical uye chimwe chikamu chinotorwa ne medium (girazi) pachayo. Yekutanga yakawedzera nekuwedzera kwe refractive index yegirazi. Kune high-refractive-index girazi, kukosha uku kwakakura kwazvo. Semuenzaniso, kurasikirwa kwe light reflection kweimwe pamusoro pe counterweight flint glass inenge 6%. Saka, kune optical system ine multiple thin lenses, nzira huru yekuwedzera transmittance ndeyekuderedza kurasikirwa kwe reflection ye lens pamusoro, sekuputira pamusoro ne anti-reflection coating. Kune hombe-size optical zvikamu zvakaita se objective lens ye astronomical telescope, transmittance ye optical system inonyanya kutsanangurwa ne light absorption coefficient yegirazi pachayo nekuda kwehukuru hwayo. Nekuvandudza kuchena kwezvinhu zvegirazi uye kudzivirira chero tsvina yemavara kuti isasanganiswe mukuita kwese kubva pakusanganiswa kusvika pakunyungudika, chiyero chekunyungudika kwegirazi chinogona kunge chiri pasi pe0.01 (kureva kuti, kufambiswa kwechiedza kwegirazi rine ukobvu hwe1 cm kwakakura kupfuura 99%).
Saida Giraziikambani inozivikanwa pasi rose yekugadzira magirazi akadzika, ine mutengo unokwikwidzana uye nguva yekutumira. Iine magirazi akagadziridzwa munzvimbo dzakasiyana-siyana uye inonyanya kugadzira magirazi ekubata, magirazi ekuchinja, magirazi eAG/AR/AF/ITO/FTO/Low-e ekubata skrini yemukati nekunze.
