Ntau yam specifications ntawm optical iav tiaj tus convex tsom lens

Magnifying yog dab tsiiav Lens?

Lawv yog cov tsom iav uas ua los ntawm cov iav lo ntsiab muag, xws li iav ntsuab, iav qhov muag pom, K9, thiab lwm yam.cov khoom siv ntawm cov iav kho qhov muag yog qhov ruaj khov thiab qhov ntsuas lub cev yog nruab nrab.Nws yuav tsis muaj hnub nyoog li yooj yim hauv kev siv mus sij hawm ntev thiab qhov saum npoo yog yooj yim kho, tib lub sij hawm, lub iav magnifier tseem tuaj yeem tau txais kev kho qhov muag zoo dua, uas tuaj yeem ua tiav ntau yam zoo dua, kev sib piv siab, kev tiv thaiv infrared thiab ultraviolet, thiab lwm yam.

Cov iav Ameslikas siv los ua cov lo ntsiab muag yog cov pob ntawm lub qhov rais zoo tib yam iav los yog lub raj mis cawv.Cov duab zoo ib yam li "crown", uas lub npe ntawm cov iav iav los yog yas phaj iav los.Lub sijhawm ntawd, lub khob tsis sib xws thiab ua npuas ncauj.Ntxiv nrog rau cov iav yas, muaj lwm hom flint iav nrog cov ntsiab lus siab txhuas.Nyob ib ncig ntawm 1790, Pierre Louis junnard, ib tug neeg Fab Kis, pom tias cov iav ua kua ntses tuaj yeem ua rau iav nrog kev ntxhib los mos.Xyoo 1884, Ernst Abbe thiab Otto Schott ntawm Zeiss tau tsim Schott glaswerke Ag nyob rau hauv Jena, Lub teb chaws Yelemees, thiab tsim ntau lub tsom iav kho qhov muag hauv ob peb xyoos.Ntawm lawv, qhov kev tsim ntawm barium yas iav nrog siab refractive index yog ib qho tseem ceeb ua tiav ntawm Schott iav Hoobkas.

Cheebtsam:

Kho qhov muag iav yog tov nrog oxides ntawm high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, thiab lwm yam raws li ib tug tshwj xeeb formula, melted ntawm kub kub nyob rau hauv ib tug platinum crucible, stirred tusyees nrog ultrasonic yoj. tshem tawm npuas;Tom qab ntawd maj mam txias rau lub sijhawm ntev kom tsis txhob muaj kev ntxhov siab sab hauv hauv lub khob thaiv.Lub khob txias txias yuav tsum tau ntsuas los ntawm cov cuab yeej kho qhov muag los xyuas seb qhov purity, transparency, uniformity, refractive index thiab dispersion index raws li cov specifications.Qhov tsim nyog iav thaiv yog rhuab thiab forged los tsim optical lens ntxhib embryo.

Kev faib tawm:

Cov iav uas muaj cov tshuaj lom neeg zoo sib xws thiab cov khoom siv kho qhov muag kuj tau muab faib rau hauv cov haujlwm nyob ib sab ntawm daim duab abet.Lub abettu ntawm Schott iav Hoobkas muaj ib txheej ntawm cov kab ncaj thiab nkhaus, uas faib abettu rau ntau qhov chaw thiab faib cov iav kho qhov muag;Piv txwv li, iav iav K5, K7 thiab K10 yog nyob rau hauv cheeb tsam K, thiab flint iav F2, F4 thiab F5 yog nyob rau hauv cheeb tsam F. Cov cim nyob rau hauv lub npe iav: F stands rau flint, K rau yas phaj, B rau boron, ba rau barium. , LA rau lanthanum, n rau cov hmoov lead-dawb thiab P rau phosphorus.
Rau lub iav lo ntsiab muag, lub kaum sab xis loj dua, cov duab loj dua, thiab muaj peev xwm paub qhov txawv ntawm cov khoom.Tsiv los ze zog rau ib qho khoom tuaj yeem ua rau kom pom lub kaum ntse ntse, tab sis nws raug txwv los ntawm lub peev xwm tsom ntawm qhov muag.Siv lub iav tsom iav kom nws nyob ze ntawm lub qhov muag, thiab muab cov khoom tso rau hauv nws qhov kev tsom mus rau tsim cov duab virtual.
Lub luag haujlwm ntawm lub iav tsom iav yog txhawm rau nthuav lub kaum sab xis ntawm qhov pom.Keeb kwm, nws tau hais tias daim ntawv thov ntawm iav tsom iav tau thov los ntawm grosstest, tus npis sov ntawm Askiv nyob rau xyoo pua 13th.

Cov iav lo ntsiab muag yog khawb tiv taus ntau dua li lwm cov lo ntsiab muag, tab sis nws qhov hnyav kuj hnyav, thiab nws qhov ntsuas qhov tsis zoo yog qhov siab: cov yeeb yaj kiab zoo tib yam yog 1.523, cov yeeb yaj kiab ultra-nyias yog ntau dua 1.72, mus txog 2.0.

Lub ntsiab raw khoom ntawm iav lens yog optical iav.Nws qhov refractive index yog siab dua li ntawm cov iav lo ntsiab muag, yog li nyob rau hauv tib lub degree, iav lo ntsiab muag yog thinner dua li resin lens.Lub iav lo ntsiab muag muaj lub teeb pom kev zoo thiab cov khoom siv hluav taws xob thiab tshuaj lom neeg, qhov ntsuas qhov ntsuas tsis tu ncua thiab ruaj khov lub cev thiab tshuaj lom neeg.Lub lens tsis muaj xim yog hu ua optical white tray (dawb zaj duab xis), thiab cov xim liab hauv cov xim xim hu ua croxay lens (liab zaj duab xis).Croxay lens tuaj yeem nqus tau cov kab hluav taws xob ultraviolet thiab me ntsis nqus lub teeb muaj zog.

Cov iav ntawv muaj cov khoom siv kho qhov muag zoo tshaj plaws, tsis yooj yim rau khawb, thiab muaj qhov ntsuas siab refractive.Qhov siab dua qhov refractive index, lub lens thinner.Tab sis lub iav yog qhov tsis yooj yim thiab cov khoom siv hnyav heev.

Lub lens twg yog siv rau hauv iav magnifying?

Convex lens
Lub iav tsom iav yog lub lens convex siv los ua ib qho khoom tshwm sim ntau dua li qhov tseeb.Qhov no ua haujlwm thaum cov khoom muab tso rau ntawm qhov deb tsawg dua qhov focal ntev.

Kuv xav tau dab tsi magnifying iav?

Feem ntau hais lus, 2-3X magnifier muab qhov loj ntawm qhov pom yog qhov zoo dua rau kev ua haujlwm zoo li kev nyeem ntawv, thaum lub teb me me cuam tshuam nrog kev nthuav dav dua yuav tsim nyog rau kev tshuaj xyuas cov khoom me me.
