亞克力表面硬化這種板能常用在手機、顯示屏、儀表面板等各類常被接觸到的顯示面板上。亞克力又叫有機玻璃，也叫壓克力，是一種高分子聚酯化合物，由于硬度不是很高，也容易產(chǎn)生劃痕，因此表面必須加硬，這個過程叫亞克力表面硬化處理，也有的人叫表面鍍膜。????因為不有經(jīng)過硬化過的亞克力板不納劃傷，而通過表面硬化處理的亞克力板硬度從H能增加到4H以上，所以它的作用是防止劃傷。加上現(xiàn)有工藝和設(shè)備的處理，能夠使防刮花亞克力鏡片大量生產(chǎn)應(yīng)用于手機屏鏡片

<p> B.折射率相對高：普通片為1.523，超薄片為：1.72以上，比較高可達1.9。 </p> <p> C.硬度高：要用鉆石切割，表面不容易被硬物劃傷。 </p> <p> D.無彈性：斷裂、伸拉彈性為零，容易遇到突發(fā)性外力發(fā)生粉碎性破碎，容易對眼睛造成意外傷害。 </p> <p> E.輔助功能：可進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> <p> F.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><p> 鏡片的種類 </p> <p> 從功能來說：有近視鏡、遠視鏡、老花鏡、散光鏡、防風(fēng)沙鏡、太陽鏡、防紫外鏡、電焊鏡、防紅外鏡等 </p> <p> 從材質(zhì)分的種類：有玻璃鏡片、樹脂鏡片、天然水晶鏡片等 </p> <p> <br /> </p> <p> 2.鏡片材料的基本特性。 </p> <p> 可以制作光學(xué)鏡片的前提條件： </p> <p> 鏡片材料的折射率：透明媒質(zhì)的折射率是光線在真空中的速度c與在媒質(zhì)中的速度v的比值，n=c/v。 </p> <p> 目前市場所采用的鏡片材料的折射率范圍是從1.5--1.9 </p> <p> 色散系數(shù)（阿貝Abbe數(shù)）因媒質(zhì)的折射率隨光波長不同而改變，故白光（復(fù)合光）在經(jīng)過透明介質(zhì)時，被分解成連續(xù)色帶的現(xiàn)象叫色散。色散大小用色散系數(shù)來表示。 </p> <p> 色散系數(shù)：是指光學(xué)媒質(zhì)將光分解成光譜的程度，色散系數(shù)越大分成的寬度越大。一般眼鏡的色散系數(shù)范圍為30~60。 1962年出現(xiàn)了代光致變色玻璃材料,此后性能不斷得到改良。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
