Chii chinonzi KukudzaGirazi Lenzi?
Iwo ari kukudza lenzi akagadzirwa negirazi lenzi, seGreen girazi, Optical girazi lens, K9, zvichingodaro.zvinhu zvegirazi remaziso hazvina kugadzikana uye indekisi yemuviri iri pakati nepakati.Izvo hazvizochembera zviri nyore mukushandiswa kwenguva refu uye pasi iri nyore kurapa, panguva imwe chete, iyo girazi yekukudza inogona zvakare kurongeka yakarongeka yekurapa coating kurapwa, iyo inogona kuwana akawanda epamusoro mhedzisiro, yakakwirira kuenzanisa transmittance, anti infrared uye. ultraviolet, nezvimwewo.
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.Kuwedzera kune girazi rekorona, kune imwe mhando yegirazi inopenya 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 budiriro yeSchott girazi fekitori.
chikamu:
Girazi yemaziso inosanganiswa neokisidhi yesilicon yakakwirira-kuchena, boron, sodium, potasium, zinc, lead, magnesium, calcium, barium, etc. maererano nemhando chaiyo, yakanyungudutswa pakupisa kwepamusoro mu platinum crucible, yakamutswa zvakaenzana ne ultrasonic wave. kubvisa mabubbles;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.
Classification:
Magirazi ane akafanana makemikari kuumbwa uye optical zvimiro zvinogoverwawo munzvimbo dziri padyo padhiyagiramu yeabet.Iyo abettu yeSchott glass factory ine seti yemitsara yakatwasuka uye macurves, iyo inoparadzanisa abettu munzvimbo dzakawanda uye inoronga girazi remaziso;Somuenzaniso, girazi rekorona K5, K7 neK10 dziri munharaunda K, uye girazi re flint F2, F4 uye F5 dziri munharaunda F. Zviratidzo mumazita egirazi: F inomirira flint, K yekorona ndiro, B ye boron, ba ye barium , LA for lanthanum, n for lead-free uye P for phosphorus.
Kune girazi regirazi, yakakura kona yekuona, yakakura mufananidzo, uye inokwanisa kusiyanisa zvakadzama zvechinhu.Kuswedera pedyo nechinhu kunogona kuwedzera kona yekuona, asi inoganhurwa nekugona kwekutarisa kweziso.Uchishandisa girazi rinokudza kuita kuti rive pedyo neziso, woisa chinhu mukati mekutarisa kwacho kuti chigadzire mufananidzo chaiwo.
Basa rekukudza girazi nderekurisa kona yekuona.Kubva kare, zvinonzi kushandiswa kwegirazi rinokudza kwakakurudzirwa naGrosstest, bhishopi weEngland muzana remakore rechi13.
Girazi regirazi rinoramba kukwenya kupfuura mamwe malenzi, asi huremu hwaro hunorema, uye refractive index yaro yakati wandei: firimu rakajairwa i1.523, firimu rakatetepa rinopfuura 1.72, kusvika 2.0.
Chinhu chikuru chegirazi lens igirazi remaziso.Iyo refractive index yakakwira kupfuura iyo resin lens, saka pasi pedhigirii rimwe chete, girazi regirazi rakatetepa kupfuura resin lens.Iyo girazi lenzi ine yakanaka mwenje transmittance uye mechanic uye makemikari zvivakwa, inogara ichiratidzira index uye yakagadzikana yemuviri nemakemikari zvimiro.Lens isina ruvara inonzi optical white tray (white film), uye firimu yepinki mufirimu ine ruvara inonzi croxay lens (firimu tsvuku).Croxay lens inogona kutora ultraviolet rays uye zvishoma inotora chiedza chakasimba.
Iro girazi pepa rine yepamusoro optical properties, haisi nyore kukwenya, uye ine high refractive index.Iyo yakakwirira iyo refractive index, iyo yakaonda iyo lens.Asi girazi racho harina kusimba uye zvinhu zvacho zvinorema.
Ndeipi lenzi inoshandiswa mukukudza girazi?
Convex lens
Girazi rinokudza igirazi rakakomberedzwa rinoshandiswa kuita kuti chinhu chiratidzike chakakura kudarika zvachiri.Izvi zvinoshanda kana chinhu chikaiswa chinhambwe zvishoma pane kureba kwefocal.
Chii chandinoda girazi rekukudza?
Kazhinji kutaura, 2-3X magnifier inopa nzvimbo yakakura yekuona iri nani pakuongorora zviitiko sekuverenga, nepo ndima diki ine chekuita nehukuru hwepamusoro ingave yakakodzera kuongororwa kwezvinhu zvidiki.
