Optical Lens

Optical lens ndiyo lens yakagadzirwa negirazi remaziso.Tsanangudzo yegirazi regirazi igirazi rine yunifomu optical zvivakwa uye zvakanangana zvinodiwa zve optical zvimiro senge refractive index, dispersion, transmittance, spectral transmittance uye mwenje kutorwa.Girazi iro rinogona kushandura nzira yekuparadzira kwechiedza uye hukama hwekutarisa kwe ultraviolet, inooneka kana infrared mwenje.Mupfungwa nhete, girazi remaziso rinoreva girazi remaziso risina ruvara;Mupfungwa yakafara, girazi remaziso rinosanganisira girazi reruvara, laser girazi, quartz optical girazi, anti radiation girazi, ultraviolet infrared optical girazi, fiber optical girazi, acoustooptic girazi, magneto-optical girazi uye photochromic girazi.Girazi remaziso rinogona kushandiswa kugadzira lenzi, maprism, magirazi uye mahwindo mune zviridzwa zvemaziso.Izvo zvikamu zvinoumbwa negirazi remaziso ndizvo zvikamu zvakakosha mumidziyo yemaziso.

Girazi raimboshandiswa kugadzira lenzi ndiwo mapundu pagirazi repahwindo kana mabhodhoro ewaini.Chimiro chakafanana ne "korona", kubva kune iyo zita rekorona girazi kana korona ndiro girazi rinouya.Panguva iyoyo, girazi rakanga risina kuenzana uye furo.Mukuwedzera kune girazi rekorona, kune imwe mhando yegirazi yeflint ine yakakwirira lead yemukati.Kuma1790, Pierre Louis junnard, murume wechiFrench, akawana kuti kubvongodza girazi muto waigona kugadzira girazi rine yunifomu.Muna 1884, Ernst Abbe naOtto Schott veZeiss vakagadzira Schott glaswerke Ag muJena, Germany, uye vakagadzira akawanda emagirazi emaziso mukati memakore mashoma.Pakati pavo, kugadzirwa kwe barium korona girazi ine yakakwira refractive index ndeimwe yeakakosha akabudirira eSchott girazi fekitori.

Girazi remaziso rinosanganiswa neokisijeni yesilicon yakakwira-kuchena, boron, sodium, potasium, zinc, lead, magnesium, calcium uye barium maererano neimwe fomula, yakanyungudutswa pakupisa kwakanyanya mu platinum crucible, yakamutswa zvakaenzana ne ultrasonic wave kubvisa mabhubhu. ;Zvadaro pora zvishoma nezvishoma kwenguva yakareba kuti udzivise kushungurudzika kwemukati mubhokisi regirazi.Iyo yakatonhodzwa girazi block inofanirwa kuyerwa nezviridzwa zvemaziso kutarisa kana kuchena, pachena, kufanana, refractive index uye dispersion index zvinosangana nezvinodiwa.Iro girazi rakakodzera rinodziiswa uye rinoumbwa kuita optical lens rough embryo.
