平板鏡片是PMMA或PC經(jīng)印刷及CNC切割而獲得的鏡片，主要材料有PMMA和PC。如果對(duì)鏡片鏡片表面的硬度要求不高，甚至可以直接使用生板(未經(jīng)過(guò)強(qiáng)化的板材)作為平板鏡片的材料，以降低成本。PC：和PMMA相比，PC的沖擊韌性更好、但在其他指標(biāo)上和PMMA還存在差距，尤其是表面硬度。在經(jīng)過(guò)表面硬化處理后，硬度也*為HB左右，鏡片在使用過(guò)程中極易被劃傷。如對(duì)鏡片的耐沖擊性能要求不高，建議采用PMMA作為鏡片的材料。PMMA：和PC相比，PMMA的透光率高，可達(dá)92%。耐候性好，不易氧化、開(kāi)裂。表面硬度未經(jīng)過(guò)硬化也可以達(dá)到H以上，經(jīng)過(guò)硬化后，硬度可以達(dá)到4H以上。板材：由于原料板材的厚度限制，光明手機(jī)pc鏡片定做，PMMA平板材料的常用規(guī)格(厚度)有0.64、0.80、1.0、1.2、1.5mm。**薄的PMMA板材的厚度可以達(dá)到0.5mm，但是隨著板材厚度降低，機(jī)械強(qiáng)度也會(huì)大幅下降，光明手機(jī)pc鏡片定做。因此建議使用0.8mm以上厚度的板材作為鏡片材料。PMMA板材厚度尺寸均勻，無(wú)縮水，無(wú)強(qiáng)化時(shí)在產(chǎn)生的彩虹。光學(xué)性能比注塑及IML更好。適用于上下表面平直，無(wú)倒扣、熱熔柱等的鏡片。特別適用于攝像頭，光明手機(jī)pc鏡片定做，翻蓋手機(jī)內(nèi)屏。

PC鏡片上打吸盤(pán)準(zhǔn)備磨邊，與對(duì)待其它材料沒(méi)什么不一樣。避免吸盤(pán)在鏡片上超過(guò)一小時(shí)，因?yàn)橐恍┪P(pán)與鏡片表面膜層接觸時(shí)間過(guò)長(zhǎng)就會(huì)粘在一起，會(huì)對(duì)膜層有所傷害。 </p> <p> 一般人習(xí)慣把小吸盤(pán)打在鏡片的光學(xué)中心。當(dāng)所要加工的PC鏡片的寬度（A值）比高度（B值）大許多，例如長(zhǎng)方形或扁橢圓形，而瞳距又要求移光心時(shí)，建議將吸盤(pán)打在鏡片的幾何中心。這樣可以避免因過(guò)度不對(duì)稱(chēng)而導(dǎo)致磨邊過(guò)程中鏡片變形，給裝鏡帶來(lái)麻煩. </p> <p> 如果磨邊輪（或刀）保持鋒利的話，大多數(shù)典型的磨邊設(shè)備都可以切出滿(mǎn)意的PC鏡片。磨邊的粗磨階段要干磨，避免用冷卻液（水），而在精磨或拋光階段可以濕磨。因?yàn)楫a(chǎn)生的熱量**小，刀式干切法比較適合PC鏡片的磨邊。但市面上的大部分磨邊機(jī)是輪式的。這種輪式磨邊機(jī)配上為PC鏡片設(shè)計(jì)的粗磨輪也完全滿(mǎn)足要求，只是濕磨階段的磨削速度一定不能過(guò)快。磨邊腔室要保持干凈。若發(fā)現(xiàn)鉆石輪上有殘屑，可用玻璃片或竹筷子***。磨片過(guò)程中若鏡片周?chē)休^大塊之殘屑，可以手輔助取下以方便磨片之進(jìn)行，避免對(duì)鏡片造成傷害。磨邊機(jī)需定期清洗，保持清潔。廣東強(qiáng)化pc鏡片硬度美國(guó)GE（通用電氣）公司率先發(fā)展了PC（聚碳酸酯）塑料，并稱(chēng)之為L(zhǎng)exan。</p><div

某些自動(dòng)磨邊機(jī)帶開(kāi)槽、倒邊。這些一體化的功能用做普通樹(shù)脂鏡片加工沒(méi)有問(wèn)題。但不建議用來(lái)做相應(yīng)的PC鏡片的加工。如果想要利用這些現(xiàn)代的自動(dòng)磨邊機(jī)所帶來(lái)的便利，那就要在加工過(guò)程中多加注意了。有些全自動(dòng)磨邊機(jī)在PC鏡片上開(kāi)槽時(shí)，會(huì)做兩次以便槽開(kāi)的更干凈。在***次開(kāi)槽后后先進(jìn)行拋光再做第二次開(kāi)槽。為避免***次開(kāi)槽留下的碎屑在拋光時(shí)被壓在鏡片邊緣而影響美觀，建議在***次開(kāi)槽時(shí)，一般旋轉(zhuǎn)一般用帶直邊的塑料鏟或廢鏡片將易***的碎屑刮掉。若開(kāi)槽后，溝槽中仍然殘留有碎屑，可使用金屬針伸入溝槽內(nèi)***。市面上也有一種專(zhuān)門(mén)用來(lái)清理PC鏡片開(kāi)槽的小工具刀（開(kāi)槽修邊器），由活動(dòng)螺絲刀把裝上特殊形狀的刀片組成，使用很方便。 </p> <p> 一般建議用**的自動(dòng)開(kāi)槽機(jī)做PC鏡片的開(kāi)槽。這種開(kāi)槽機(jī)使用方便，槽位靈活。所有國(guó)產(chǎn)自動(dòng)開(kāi)槽機(jī)都可以勝任，只是需要配一片高質(zhì)量的開(kāi)槽砂輪。用于PC鏡片開(kāi)槽的砂輪要比一般的粗糙些。也有人建議用帶缺口的開(kāi)槽砂輪。?同磨邊一樣，PC鏡片開(kāi)槽也不能有水。在開(kāi)槽之前按照加工無(wú)框架的方法加工，在開(kāi)槽時(shí)先不加水開(kāi)一圈，再加水開(kāi)一圈，這樣減少開(kāi)槽時(shí)鏡片留下的白色殘留物。 </p><p> PC鏡片的正確裝配 </p> <p> 當(dāng)裝配鏡片時(shí)，要考慮將內(nèi)應(yīng)力降到**小。過(guò)大的內(nèi)應(yīng)力會(huì)導(dǎo)致鏡片膜層龜裂。**容易引入內(nèi)應(yīng)力的機(jī)會(huì)出現(xiàn)在鏡片與鏡框大小不合的時(shí)候。鏡片的尺寸如果太大的話應(yīng)在精磨輪上做修正。把裝有鏡片的鏡框放置在應(yīng)力儀（兩片偏光片之間）下可以清楚的觀察到鏡片中應(yīng)力集中的地方。通常壓力較大的部份會(huì)較亮節(jié)呈現(xiàn)紫色或黃色，此時(shí)可將鏡片的邊磨小一點(diǎn)或?qū)⒙萁z放松一些，直到壓力消失。 </p> <p> 為了便于在磨邊機(jī)上修正鏡片，請(qǐng)把小吸盤(pán)留在鏡片上，確定鏡片裝配合適后再取下。 </p> <p> 裝金屬全框鏡時(shí)，螺絲松緊要適中。裝板材全框鏡時(shí)，尤其要注意鏡片的大小。必要時(shí)，先模擬整個(gè)裝鏡過(guò)程，以免手忙腳亂。遵守裝配板材框的規(guī)則(如預(yù)熱鏡框)，避免造成鏡片中心部位的過(guò)大變形，否則有發(fā)生AR膜產(chǎn)生龜裂的可能。是鋼化玻璃的2-20倍，用3kg錘以下兩米墜下也無(wú)裂痕，有“不碎玻璃”和“響鋼”的美稱(chēng)。</p><div

樹(shù)脂鏡片，PC鏡片，玻璃鏡片的區(qū)別樹(shù)脂鏡片是一種以樹(shù)脂為原材料經(jīng)過(guò)精密的化學(xué)工藝進(jìn)行加工合成和打磨后制作而成的一種光學(xué)鏡片。樹(shù)脂又可分為天然樹(shù)脂和合成樹(shù)脂兩種。樹(shù)脂鏡片的優(yōu)點(diǎn)：抗沖擊強(qiáng)，不易碎，透光性好，折射率高、質(zhì)量輕，成本低廉。pc鏡片是用聚碳酸酯(熱塑性材料)經(jīng)過(guò)加熱后塑形而成的一種鏡片。這種材料它是源于太空探險(xiǎn)而研制成的，故又被稱(chēng)為宇宙片或太空片。由于PC樹(shù)脂是一種性能優(yōu)良的熱塑性材料，所以特別適宜制作眼鏡片。PC鏡片的優(yōu)點(diǎn)：**紫外線，3-5年之內(nèi)不會(huì)發(fā)黃，***的抗沖擊能力，折射率高、比重輕(重量比普通樹(shù)脂片輕37%，抗沖擊力更是高達(dá)普通樹(shù)脂的12倍!)玻璃鏡片的主要原料是光學(xué)玻璃。其折射率比樹(shù)脂鏡片高，因此在同樣度數(shù)情況下，玻璃鏡片比樹(shù)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(méi)有顏色的鏡片稱(chēng)光學(xué)白托（白片），有**中的粉紅片稱(chēng)克羅克賽鏡片（紅片）?？肆_克賽鏡片能吸收紫外線、對(duì)強(qiáng)光略有吸收作用。玻璃鏡片，具有比其它材質(zhì)的鏡片更耐刮的特性，但相對(duì)其重量也較沉，其折射率相對(duì)高：普通片為，超薄片為：，比較高可達(dá)。玻璃片的優(yōu)點(diǎn)：光學(xué)性質(zhì)優(yōu)越，不容易劃花，折射率高。

PC比較大缺點(diǎn)即是產(chǎn)生應(yīng)力開(kāi)裂。生產(chǎn)中除了選用高純度原料，嚴(yán)格控制各種加工條件外，采用內(nèi)應(yīng)力小的樹(shù)脂改性，如少量的聚烯烴、尼龍、聚酯等熔融共混，可***改進(jìn)抗應(yīng)力開(kāi)裂性、抗水性。 </p> <p>

PET的膨脹系數(shù)小，成型收縮率低，*0．2％，是聚烯烴的十分之一，較PVC和尼龍小，故制品的尺寸穩(wěn)定。機(jī)械強(qiáng)度堪稱(chēng)比較好，其擴(kuò)張程度與鋁相似，薄膜強(qiáng)度為聚乙烯的9倍、聚碳酸酯和尼龍的3倍，沖擊強(qiáng)度是一般薄膜的3～5倍。而其薄膜又有防潮和保香性能。雖然聚酯具有上述優(yōu)點(diǎn)，但是其薄膜價(jià)格較貴，熱封困難，易帶靜電，所以單獨(dú)使用極少，大多是用熱封性較好的樹(shù)脂涂布共同制成復(fù)合薄膜。
