1, Ungasarudza sei?
Kana uchifananidza magirazi, rasvika riini kuti usarudze chinongedzo cheLens, Magirazi Party haina kurasikirwa?Hauzive Maitiro ekusarudza iyo Lens.Heano maitiro ekusarudza iyo lens yakakodzera yedhigirii rako.
2, The refractive index
Iyo refractive index ireshiyo yekumhanya kwechiedza muvacuum kune iyo yechiedza mune lens zvinhu.
Iyo yakakwira iyo refractive index, iyo Lens yakatetepa, ndiko kuti, ukobvu hwakafanana hwepakati peLens, nhamba yakafanana yemadhigirii echinhu chimwe chete Lens, iyo yakakwira iyo refractive index pane yakaderera ukobvu hweLens Edge.Iyo yakakwirira iyo refractive indekisi yezvinyorwa, iyo inosimba kugona kudzoreredza chiitiko chiedza.
Parizvino, iyo huru refractive index ye lens pamusika ndeye: 1.56,1.61,1.67,1.74.
Kazhinji yekutanga parameter vanhu vazhinji vanosangana nelenzi ndiyo refractive index.Ipapo ndiyo yakanyanya kujeka embodiment yeLens ndeye: Iyo Yepamusoro Iyo refractive index, iyo yakatetepa iyo Lenzi.
Kune runako uye uremu zvinodiwa, matete lenzi isarudzo yakanaka.
3、Abbe nhamba
Mukusarudza lenzi, imwe kiyi data izwi rakabatana nerenzi nhamba yeabbe.Saka nhamba yeAbelian chii?
Nhamba yeErnst Abbe inoreva dispersion factor, iyo inoshandiswa kuyera kupinza kwemufananidzo welenzi.Iyo yakakwirira iyo ABBE nhamba, iyo idiki yekupararira, yakajeka uye inonyanya kuona maitiro ekuona.
Ziso remunhu rine nhamba yeabbe ye58.6, uye kana iri pedyo nenhamba yeErnst Abbe yeLens, iyo lens ichanyanya kugadzikana.
4, Refractive index reference value
A, kana dhigirii iri 0-200 madhigirii, tinokurudzira kushandiswa kwe1.56 refractive index lenses.
B, kana dhigirii mu200-350 madhigirii, tinokurudzira kushandiswa kwe1.61 refractive index lenses.
C, kana dhigirii mu 350-550 madhigirii, tinokurudzira kushandiswa kwe1.67 refractive index lenses.
D, kana dhigirii ye550-800 madhigirii uye anopfuura 800 madhigirii, tinokurudzira kushandiswa kwe1.74 refractive index lenses.
5. Mazano
Kana chinhambwe chemudzidzi chiri chidiki kwazvo, kana saizi yakasarudzwa yakakurisa, zvinokurudzirwa kuwedzera refractive index.
Pakusarudza furemu, munhu anofanirwa kufunga nezvekudyidzana neLens:
Iyo yakakura saizi yefuremu, yakakura dhayamita yeLens, uye kukora mipendero yefuremu.
Usafunge kuti kusarudzwa kweyepamusoro refractive index Lens, ita mupendero wemagirazi uchave wakaonda kwazvo, ichi chikanganiso, nekuti iyo yakafanana nhamba yemalenzi akaitwa nekuti ukobvu hwemwana chinhambwe, astigmatism, axis, furemu saizi. uye zvakasiyana.
Nokudaro, patinosarudza lens inokodzera dhigirii yedu, tinofanira kufunga nezvezvinhu zvose, kuitira kuti magirazi ave akasununguka kupfeka.
