MR-174 ndiye nyenyezi ya banja la MR mndandanda, wokhala ndi cholozera chapamwamba kwambiri pamndandanda, ndikupangitsa kuti ikhale mandala owonda kwambiri komanso owala.
Zinthu za MR-174 zili ndi index yowonekera ya 1.74, AbbeMtengowa 32, ndi kutentha kupotoza kutentha kwa 78°C. Imafikira kupepuka komanso kuonda kwambiri, imagwiritsanso ntchito zinthu za "Do Green" zochokera kuzinthu zakubzala.
MR-174 ndi choyimira chowongolera kwambiri pamsika wapadziko lonse lapansi wa mandala. Chifukwa chake, ogula omwe ali ndi madigiri apamwamba, kapena ogula omwe amatsata magalasi ochepa komanso opepuka komanso okhudzidwa kwambiri ndi chitetezo cha chilengedwe, amagula kwambiri MR. Magalasi opangidwa ndi -174 zakuthupi.
Mau oyamba a Zopanga
Kuyerekeza kwa 1.74 ndi 1.67:
1.67 ndi 1.74 onse amaimira refractive index ya mandala, ndipo kusiyana kwake kuli m'mbali zinayi zotsatirazi.
1. Makulidwe
Kukwera kwa index ya refraction ya zinthu, kumapangitsanso mphamvu yowunikira kuwala kwazomwe zikuchitika. Kukwera kwa refractive index, kumachepetsa makulidwe a lens, ndiko kuti, makulidwe apakati a lens ndi ofanana, mlingo womwewo wa zinthu zomwezo, m'mphepete mwa lens wokhala ndi index yayikulu yowonera ndi yocheperapo kuposa m'mphepete mwa mandala okhala ndi index yotsika ya refractive.
Izi zikutanthauza kuti, pamlingo womwewo, mandala omwe ali ndi index ya refractive ya 1.74 ndi yocheperako kuposa mandala omwe ali ndi index ya 1.67.
2. Kulemera
Mlozera wapamwamba wa refractive, magalasi ocheperako, ndi ma lens opepuka kuti muvale bwino.
Izi zikutanthauza kuti, pamlingo womwewo, mandala okhala ndi index ya 1.74 ndi yopepuka kuposa mandala omwe ali ndi index ya 1.67.
3. AbabeMtengo(dispersion coefficient)
Nthawi zambiri, ma lens amakwera kwambiri, m'pamenenso mawonekedwe a utawaleza ali m'mphepete mwake poyang'ana zinthu. Ichi ndi chikhalidwe chobalalika cha lens, chomwe nthawi zambiri chimawonetsedwa ndi AbbeMtengo(dispersion coefficient). Aabe apamwambaMtengo, chabwino. Pafupifupi AbbeMtengomagalasi ovala anthu sangakhale otsika kuposa 30.
Komabe, Mtengo wa Abbe wa ma lens awiriwa omwe amawonekera siwokwera, pafupifupi 33 okha.
Nthawi zambiri, kuchuluka kwa refractive index ya zinthu kumachepetsa mtengo wa Abbe. Komabe, pakukweza kwaukadaulo wazinthu zamagalasi, lamuloli likuphwanyidwa pang'onopang'ono.
4. Mtengo
Kukwera kwa refractive index ya mandala, mtengo wake ndi wokwera mtengo. Mwachitsanzo, mandala 1.74 a mtundu womwewo akhoza kukhala oposa5mtengo 1.67 Yuro.
