J.鏡片的尺寸設(shè)計：美國藥品與食品管理局“F.D.A”標準中規(guī)定，中心厚度比較低可設(shè)計至0.6毫米，但強度要求卻相應(yīng)降低，為此歐洲、美國、日本等國生產(chǎn)商一般把近視、遠視100度以上的鏡片**厚度設(shè)計在1.0毫米以上，觀瀾批發(fā)鏡片面板，以保證鏡片的整體強度。常用的光學(xué)樹脂材料有：丙烯基二甘醇碳酸酯（CR-39）聚甲基丙烯酸甲酯（PMMA）聚碳酸酯（PC）三大類。折射率可以使用以下任意一種技術(shù)來增加： </p> <p> （1）改變原子分子中電子的結(jié)構(gòu)，例如：引入苯環(huán)結(jié)構(gòu)； </p> <p> （2）在原分子中加入重原子，觀瀾批發(fā)鏡片面板，觀瀾批發(fā)鏡片面板，諸如鹵素（氯、溴等）或硫。與傳統(tǒng)CR-39相比，用中高折射率樹脂材料制造鏡片使得更輕、更薄。天然水晶片握在手中始終是涼的,而人造的就會變暖.觀瀾批發(fā)鏡片面板</p><div style="width:100%;text-align: center;"><img style="max-width:

光學(xué)樹脂鏡片是一種有機材料，內(nèi)部是一種高分子鏈狀結(jié)構(gòu)，分子間結(jié)構(gòu)相對松馳，分子鏈間有可產(chǎn)生相對位移的空間.光線可透過率為84%-90%。特點：A.密度低：因分子鏈間的間隙，因此單位體積內(nèi)的分子數(shù)量少，決定了樹脂鏡片的優(yōu)點：比重低，質(zhì)地輕,是玻璃鏡片的1/3-1/2。B.折射率適中：普通CR-39丙烯基二甘醇碳酸酯，折射率為，目前沈陽眼鏡市場上銷售的樹脂鏡片折射率比較高的為日本尼康非球面超薄加硬加膜折射率為。日本尼康公司將推出。C.表面硬度比玻璃較低，容易被硬物劃傷，所以需經(jīng)加硬處理，其加硬材料即為二氧化硅，但硬度絕達不到玻璃的硬度。因此需配戴者注意鏡片的保養(yǎng)。D.彈性好,由于有機物分子鏈間有可產(chǎn)生位移的空間的原因，相對強度是玻璃片的23-28倍。決定了樹脂片又一大特性——抗沖擊性好。歐洲、美國、日本國家禁止十六歲以下兒童配戴玻璃鏡片。E.輔助功能：可進行添加處理以獲得防有害射線、變色等功能。F.加工性：優(yōu)良,可行進全框、半框、無框的多型化加工。并可進行滲透性染色，把鏡片染成個人喜愛的顏色。G.化學(xué)性：由于是一種有機化合物，因此***禁止在酸、堿環(huán)境下配戴使用。H.熱性能：不得在超過60度以上環(huán)境下使用，否則表面減反射膜將破裂。光明pmma鏡片面板加工PC/ABS這種混合材料還顯示了優(yōu)異的流動特性。</p><div

明材料的內(nèi)部產(chǎn)生。理論上眼鏡片表面沒有散射發(fā)生，因為鏡片的磨片過程（拋光）消除了這一現(xiàn)象。然而當(dāng)鏡片由于外界污染而弄臟或表面由于油漬而模糊不清時會產(chǎn)生散射。同時鏡片內(nèi)部的菜射也非常有限，只在偶爾情況下，可能會使鏡片呈現(xiàn)黃色或乳白色。目前合格的眼鏡片只有非常少量的散射光線產(chǎn)生，通常可以忽略不計。 </p> <p> (2)衍射：衍射是當(dāng)光波遇到小障礙而改變行徑方向的一種現(xiàn)象。在眼鏡光學(xué)里，衍 </p> <p> 射現(xiàn)象是需引起重視的，因為衍射會使鏡片表面產(chǎn)生異常干擾，尤其是在使用不當(dāng)或不小心在鏡片表面造成的磨損的情況下 </p><p> 鏡片材料的基本分類 </p> <p> 鏡片材料采用透明的介質(zhì)，主要分為無機和有機二大類。在我們的日常生活還會碰到一種天然介質(zhì)水晶鏡片，這是用石英礦磨制成的鏡片。古代有水晶能養(yǎng)顏明目的說法，但事實上水晶的主要成分是二氧化硅（sio2），比較大優(yōu)點是硬性度高且不易受潮，但紫外線及紅外線的透過率較高，而且水晶中密度不均勻，含雜質(zhì)，有條紋及氣泡等到產(chǎn)生，會形成雙折射現(xiàn)象，從而影響視力。無機材料--玻璃，玻璃是非常特殊的不定型材料，在常溫下呈現(xiàn)固體，堅硬但易碎，在高溫下具有粘性。玻璃沒有固定的化學(xué)結(jié)構(gòu)，因而沒有確切的熔點。隨著溫度的上升，玻璃材料會變軟、粘性增加，并逐漸由固體變?yōu)橐后w，這種逐漸變化的特性我們稱之為"玻璃狀態(tài)"。這一特性意味著玻璃在高溫時可以被加工和鑄型。玻璃材料制成的鏡片具有良好的透光性、表面拋光后更加透明的優(yōu)點加工性：一般.不能進行滲透性染色；難于用玻璃鏡片進行無框、半框的加工</p><div

（1）普通玻璃材料（1。5和1。6）：折射率為1.523的冕牌玻璃是傳統(tǒng)光學(xué)鏡片的制造材料，其中60%~70%為二氧化硅，其余則由氧化鈣、鈉和硼等多種物質(zhì)混合。有時也將折射率為1.6的鏡片劃歸普通鏡片。 </p> <p> （2）高折射率玻璃材料：經(jīng)過多年的研究，鏡片制造商已經(jīng)找到了在提高材料折射率的同時又保持低色散的方法，即在玻璃中加入新的化學(xué)元素。????早在1975年就生產(chǎn)出了含鈦元素的鏡片，折射率為1.7，阿貝數(shù)為41；15年之后又生產(chǎn)出了含鑭元素的鏡片，折射率為1.8，阿貝數(shù)為34；1995年出現(xiàn)折射率為1.9的材料，加入了元素鈮，阿貝數(shù)為30，這是目前折射率比較高的鏡片材料。雖然采用這些材料所制造的鏡片越來越薄，然而卻沒有減少鏡片的另一重要參數(shù)：重量。實際上，隨著折射率的增加，材料的比重也隨之增加，這樣就抵消了因為鏡片變薄而帶來的重量上的減輕。一般來說，亞克力標牌，就是以亞克力板為主要材質(zhì)制作而成的標示牌。觀瀾電器鏡片面板廠家</p><p
