WI-hen iyeza ngokukhetha iiglasi zamehlo, sihlala sijamelene nesigqibo esibalulekileyo: iilensi ze-sphericals okanye iilensi ze-aspherical? Ngelixa iilensi ze-spherical ziye zezona ndlela ziphambili, iilensi ze-aspherical ziye zavela njengenye indlela entsha ngoluhlu lwezinto eziluncedo. Eli nqaku liza kuphonononga umahluko phakathi kweelensi kunye neelensi ze-aspherical, kwaye zixoxe ngezinto eziluncedo kwi-lenses ye-aspherical.
Ingcaciso kunye nolwahluko:
Umahluko ophambili phakathi kwe-spherical kunye neelensi ze-aspherical zilele kwimilo yabo kunye ne-curvature yazo. Iilensi ze-spherical zine-curvature efanayo kuzo zonke iilensi, ngelixa iilensi ze-aspherical zinee-curvature ezingaqhelekanga ezinokubakho ngokwakho kwimeko yeliso lomntu ngamnye.
Inzuzo 1: Inkangeleko yendalo
Esona sibonelelo siphambili se-asphericalIilensi kukuba zibonelela ngenkangeleko yendalo. Xa kuthelekiswa neelensi ze-spherical, i-curvature leelensi ze-aspherical zinokuziqhelanisa ne-curvature yeliso, ukunciphisa ukugqwetha kwe-lens yelensi. Oku kuthetha ukuba abaphethe iilensi ze-aspherical babone ngokucacileyo imifanekiso ngokucacileyo kwaye benganyaniseki, ngaphandle kokukhathazeka malunga nokuguquguquka kwemilo yelensi ebonakalayo kwabanye.
Inzuzo 2: Intsimi ebanzi
Ukongeza kwinzuzo yobuhle, iilensi ze-aspherical zibonelela ngembonakalo ebanzi. Iilensi ze-Aspherical zenzelwe ukuqwalasela imeko yomfundi kunye ne-curvature ye-retina, ukunciphisa ukugqwetha okubangelwa kukuvuselelwa okukhanyayo kunye nokuvumela ukuqiqa kwezinto kwilensi yazo. Oku akuboneleli kuphela abaphathi ngamava abonakalayo acacileyo kodwa anceda ukunciphisa ukudinwa kwamehlo.
Inzuzo yesi-3: I-lens ukukhanya
Iilensi ze-aspherical zihlala zilula kuneilensi eziphumayo kunye nemiyalelo efanayo. Kungenxa yokuba iilensi ze-Aspherical zihlelwe ngokwezidima, ukuthintela inkunkuma engekhoyo. Ngenxa yoko, abakhupheli banokonwabela amava anokunxiba kakhulu ngelixa enciphisa umthwalo ebunzini kunye ne-ridge yempumlo, enciphisa uxinzelelo.
Ukukhetha iiglasi zamehlo ezifanelekileyo yinkalo ebalulekileyo yokhathalelo lomntu. Iilensi ze-aspherical zibonelela ngokhetho olutsha kwi-Widglass Beiclors ngokubonelela ngembonakalo yendalo, inkalo ebanzi, kunye neelensi ezilula. Xa ufuna ukuthenga iiglasi zamehlo ezintsha, cinga iilensi ze-aspherical zezinto ezikhululekileyo nezicacileyo ezicacileyo.
