style="text-indent:25px">PC鏡片定義：一般的樹(shù)脂鏡片都是熱固性材料，即原料為液態(tài)，加熱后形成固態(tài)鏡片。PC片又叫“太空片”、“宇宙片”，化學(xué)名稱為聚碳酸酯，是熱塑性材料。即原料為固態(tài)，經(jīng)加熱后塑形為鏡片，所以這種鏡片成品后受熱過(guò)度也會(huì)變形，不適合高濕熱場(chǎng)合。PC鏡片有著極強(qiáng)韌性，不破碎（2cm可用于防彈玻璃），故又稱安全鏡片。比重每立方厘米*為2克，是目前用于鏡片的**輕材料。從鏡片的功能上講，它具有調(diào)節(jié)進(jìn)入眼睛之光亮，增加視力，保護(hù)眼睛安全和臨床***眼病的作用。對(duì)屈光異常引起的兒童斜視和伴有***的屈光異常患者，佩戴眼睛后均可***。而鏡片當(dāng)然要與鏡框搭配，還能起到美容、裝飾性的作用?，F(xiàn)代流行者強(qiáng)調(diào)，眼睛要有與時(shí)代人的面部化妝及服飾的和諧，反映社會(huì)階層高、學(xué)問(wèn)高雅、時(shí)尚等象征。</p><p> 鏡片的光學(xué)性質(zhì)：光線折射 </p> <p> <br /> </p> <p> 光學(xué)性質(zhì)是材料的基本性質(zhì)，與鏡片在日常生活中所見(jiàn)到的各種光學(xué)現(xiàn)象相符合，主要為光線在鏡片表面的折射和反射、材料本身的吸收，以及散射和衍射現(xiàn)象。 </p> <p> （1）光線折射：通過(guò)鏡片的光線會(huì)在鏡片的前后表面發(fā)生折射或偏離現(xiàn)象，光線的偏離幅度由材料的折射率和入射光線在鏡片表面的入射角度決定。??1）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， </p> <p> n=c/v。該比值沒(méi)有單位并且總是大于1。折射率反映媒質(zhì)的折射能力，折射率越高，從空氣進(jìn)入該媒介的光束偏離得越多。從空氣到折射率為n的透明媒質(zhì)所發(fā)生的偏離或折射可以根據(jù)斯涅耳-笛卡爾定律(Snell-Descartes?Law)進(jìn)行計(jì)算，規(guī)定如下：折射光線與入射光線和法線位于同一平面入射角i和折射角r分別由法線與入射光線、折射光線構(gòu)成。計(jì)算公式：?sin?i=n?sin?r????由于透明媒質(zhì)的光速隨著波長(zhǎng)而變化，所以折射率的值總是參考某一特定波長(zhǎng) </p> <p> 表示：在歐洲和日本，參考波長(zhǎng)為e線546.07nm(汞--綠光譜線)，但是在美國(guó)等其它 </p> <p> 國(guó)家則是d線587.56nm(氦--黃光譜線)。但這個(gè)區(qū)別并沒(méi)有造成實(shí)際影響，因?yàn)樗?</p> <p>

機(jī)械性質(zhì)通常反映塊狀固體材料的特性，它規(guī)定了材料的質(zhì)量、體積和尺寸，以及材料對(duì)變形和沖擊的抵抗力。我們常見(jiàn)的反映鏡片機(jī)械性質(zhì)的特性有：1、比重；2、硬度；3、彈性系數(shù)E（或楊氏系數(shù)）：壓力和在排除壓力后恢復(fù)**初形狀時(shí)產(chǎn)生的相應(yīng)變形之間的比率。4、抗沖擊性：常采用由美國(guó)食品和***管理局（FDA）規(guī)定的一項(xiàng)落球試驗(yàn)表示。落球試驗(yàn)即使用一個(gè)16克的鋼球從1.27M高處對(duì)準(zhǔn)鏡片中心落下的測(cè)試。5、抗斷開(kāi)點(diǎn)：采用由歐洲標(biāo)準(zhǔn)化**會(huì)制定的"100牛頓"CEN靜態(tài)變形測(cè)試。該測(cè)試是在一個(gè)恒定速度下增加壓力直到100牛頓。東莞pet鏡片面板批發(fā)</p></p><br
