1.base material quality.
Iyo substrate yemhando inotarisa kusimba kwe lens uye kuvimbika kwejasi.Yakanaka substrate yakajeka uye yakajeka, yakareba kushandisa nguva uye isiri nyore kune yero;Uye mamwe lenzi haatore nguva kuti aite yero, uye kunyangwe iwo machira anodonha.Lens yakanaka isina kukwenya, kukwenya, bvudzi, gomba, iyo lens inotsvedza kune iyo chiedza chekutarisa, yakakwirira kupera.Iko hakuna mavara, matombo, mitsetse, mabhuru uye kuputika mukati me lens, uye chiedza chakajeka.
2.Grade ye lens.
Malenzi anogadzirwa neMisa akakamurwa kuita mamakisi akasiyana nekuda kwekusiyana kwemukati wemhando, uye mitengo yezvigadzirwa zvepamusoro uye zvakaderera inosiyana zvakanyanya.
3.Refractive index.
Iyo yakakwirira iyo refractive index, iyo yakaonda lens, uye yakakwirira mutengo.
4.coating uye anti-ultraviolet kurapwa.
Resin pepa rinogona kuomeswa (kukwenya kuramba), anti-reflection, anti-static, guruva, isina mvura yekuputira kugadzirisa akawanda segumi nemaviri akaturikidzana, akasiyana coating process ane basa rakasiyana, kana akadzikisa coating process process, kunaka kwelens. ichaderedzwa zvakanyanya.Saizvozvo, kana ma lens asingadzivisi uv sekupfeka kwema lenses, saka zvinokuvadza zvakanyanya kumaziso.
5. Lenzi mhando.
Misiyano yemhando inotungamira kune misiyano yemhando uye mutengo.Hunhu hwe lens hunoratidzwa zvakananga mumhando ye lens.Famous brand lenses ndeyemhando yakanaka uye yakagadzikana.
6. Edza kujeka uye kufanana kwemaziso e lens.
Bata lenzi masendimita makumi matatu kubva paziso uye tarisa nzvimbo iri kure kuburikidza nelenzi.Kana nzvimbo yacho yakajeka uye isina deformation, uye pasina chiitiko chinosvetuka paunenge uchifambisa lens zvishoma nezvishoma, kujeka uye kufanana kwemaziso kwelenzi kwakanaka.
7. Sarudza iyo axial kutungamira kweastigmatism lens.
Pabepa risina kunyorwa kudhirowa perpendicular muchinjikwa forogo, isa lenzi mune spider tenderera graphic pamusoro 30 centimita, inooneka lens fambisa muchinjikwa muchinjikwa forogo, lenzi mukati uye kana akabatana sitiroko muchinjikwa Graphics, Graphics akanga zvakanaka kuyambuka, apo column lens axis uye mutsara wakatwasuka, ipapo malenzi airamba achifamba achitevedza mutsara wakatwasuka;Tarisa kuti ndeupi mutsara unosiyana zvakanyanya kubva pamutsetse uri kunze kwelenzi kana uchifamba, uye mutsetse uyu ndiwo kutungamira kweakisi ye scatterlight.
8. Edzai optical center displacement.
Dhirowa muchinjikwa muhombe papepa jena mumutsara wakaonda, wakajeka, wakatwasuka.Bata lens pakati peziso nemuchinjikwa, cherechedza chimiro chemuchinjikwa kubva pagirazi neziso rimwe, kana mukati nekunze kwegirazi zvisiri mumutsara, unogona kufambisa lens, kuitira kuti mukati me lens uye kunze kwechionioni chemuchinjikwa mutsara.Shandisa bhurashi kana chitubu chinyoreso kuti uise poindi diki pamuchinjiko pakati pe lens, inova nzvimbo yekuona.Mushure mekunongedza nzvimbo dzemaziso emalenzi ese ari maviri, tarisa uye enzanisa kana mabilateral optical centers ari symmetrical, uye yera nhambwe pakati penzvimbo mbiri nemutongi mudiki kuti uone kana chinhambwe chiri pakati penzvimbo mbiri chichienderana nechinhambwe chakatarwa kumudzidzi. .Kana muchinjikwa uri mu lens wakakotama, zvinoratidza kuti kune kushushikana kwemukati kana kusaenzana optical density ye lens.
9.kupfeka kunzwa.
Pfeka pasina chero kunzwa, dzungu, kuzvimba kweziso, kuona zvinhu hazvina kudzima, kwete kuremara.Paunenge uchitenga, bata magirazi muruoko uye tarisa zvinhu zviri kure neziso rimwe kuburikidza nelens.Zunza lenzi kumusoro nekudzika.Kunyengedza kwekufamba kwezvinhu zviri kure hazvifaniri kuitika.
10. Dziviriro.
Malensi emhando yepamusoro anogona kunyatso kuvharira UV rays uye kupa hunoshanda kuchengetedzwa kweuv kune anopfeka.
