光線在鏡片表面產(chǎn)生折射的同時，也會產(chǎn)生反射現(xiàn)象。光線反射會影響鏡片的清晰度，而且在鏡片表面會產(chǎn)生干擾性反射光。通常，鏡片材料的折射率越高，因反射而損失的光線就越多。當(dāng)然，光明電器鏡片面板批發(fā)，對于干擾性反射光可以通過在鏡片表面鍍多層減反射膜而相應(yīng)抵消。 </p> <p> 光線吸收：材料的本身吸收光的特性會減少鏡片的光線透過率，這部分的光量損失對于非染色眼鏡片是可以忽略的，但如果為染色或變色鏡片，光的吸收量會很大，這也是此類鏡片的設(shè)計目的。眼鏡片的光線吸收通常指材料內(nèi)部的光線吸收，可通過鏡片前、后表面吸收光線的百分比表示。例如，30%的光線吸收相當(dāng)于30%的光通量在鏡片內(nèi)部的減少，光明電器鏡片面板批發(fā)，光明電器鏡片面板批發(fā)。材料的光線吸收遵循郎伯(Lambert′s?Law)定律，它根據(jù)鏡片的不同厚度呈**性的變化硬度高：要用鉆石切割，表面不容易被硬物劃傷。光明電器鏡片面板批發(fā)</p><div

</p> <p> 主要包括比重（密度）、硬度、表面張力和彈性系數(shù)等。 </p> <p> 比重和硬度在眼鏡玻璃中是極其重要的參數(shù)。一般光學(xué)玻璃的比重均比較大，比重和折射率有一定的關(guān)系。折射率越大，比重也就越大，鏡片的重量就增加。光學(xué)眼鏡片的表面要求有一定的硬度，硬度不僅影響使用壽命，而且也直接影響鏡片的研磨加工質(zhì)量和速度。廣東玻璃鏡片面板廠家輔助功能：可進(jìn)行多種良好的功能化添加處理，使鏡片具有防有害射線、變色等功能.</p><div

</p> <p> 玻璃鏡片的主要原料是光學(xué)玻璃。其折射率比樹脂鏡片高，因此在同樣度數(shù)情況下，玻璃鏡片要比樹脂鏡片薄。玻璃鏡片的透光率和機(jī)械化學(xué)性能都比較好，有恒定的折射率、理化性能穩(wěn)定。沒有顏色的鏡片稱光學(xué)白托（白片），有**中的粉紅片稱克羅克賽鏡片（紅片）?？肆_克賽鏡片能吸收紫外線、對強(qiáng)光略有吸收作用。 </p> <p>

亞克力鏡片與玻璃鏡片發(fā)展趨勢誰更有力？亞克力，被稱為“塑料皇后”，因為亞克力具有質(zhì)輕、價廉，易于成型等優(yōu)點。它的成型方法有澆鑄，射出成型，機(jī)械加工、亞克力熱成型等。尤其是射出成型，可以大批量生產(chǎn)，制程簡單，成本低。因此，目前它***用于儀器儀表零件、汽車車燈、光學(xué)鏡片、透明管道等。但亞克力對于未來要求更高的手機(jī)及平板電腦鏡片來說，就比較顯拙，特別是現(xiàn)世風(fēng)日下的觸控數(shù)碼產(chǎn)品，玻璃類產(chǎn)品主要為超薄玻璃（），經(jīng)過玻璃開片、仿型磨邊、拋光、硬化、超聲清洗、真空鍍膜、絲印等一系列特殊加工工藝制作而成的產(chǎn)品。它具有美化裝飾和保護(hù)的功能。檢查鏡片紋路：對著陽光觀察鏡片，鏡片內(nèi)若有均勻細(xì)紋路或柳絮狀的物質(zhì)(俗稱“棉”)為真品。</p><div

J.鏡片的尺寸設(shè)計：美國藥品與食品管理局“F.D.A”標(biāo)準(zhǔn)中規(guī)定，中心厚度比較低可設(shè)計至0.6毫米，但強(qiáng)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(yuǎn)視100度以上的鏡片**厚度設(shè)計在1.0毫米以上，以保證鏡片的整體強(qiáng)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，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。使材料對太陽光強(qiáng)度作出反應(yīng)的一種性質(zhì)。沙井pet鏡片面板廠家</p><p

鏡片材料采用透明的介質(zhì)，主要分為無機(jī)和有機(jī)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(jī)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)點光明電器鏡片面板批發(fā)</p></p><br
