1.71 Hal aragga HMC ee muraayadaha indhaha
1.71 lens Magaca buuxa 1.71 lens index refractive, oo leh index refractive sare, gudbinta sare, sifooyinka tirada Abbe sare, xaalad isku mid ah myopia shahaado, si weyn u dhimi kara dhumucda lens, hoos u dhigi tayada lens, isla waqti, ka dhig muraayadda mid saafi ah oo dhalaalaya, ma fududa in la kala firdhiyo hadhuudh qaansoroobaad. Waxaa la ogaaday in ku darista xuubka sulfide cyclic ee walxaha lensku ay wanaajin karto index refractive of lens, laakiin aad u badan xabagta sulfide cyclic waxay horseedi doontaa dhimista gudbinta iftiinka iyo dildilaaca walxaha. Iyada oo si sax ah loo xakameynayo nuxurka resin sulfur ee 1.71KR, lens-ka 1.71 wuxuu gaaraa index refractive sare iyo lambarka abbe iyadoo la hubinayo gudbinta iftiinka wanaagsan, kala firdhisanaanta hoose iyo aragti cad.
