<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，寶安pmma鏡片面板廠家。 </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，寶安pmma鏡片面板廠家。透紅外亞克力板工作原理：各種紅外感應(yīng)上，主要功能是濾除可見光能雜散光。寶安pmma鏡片面板廠家</p><div style="width:100%;text-align: center;"><img

<p> 托力克片（Toric）：也稱白托片，白片?？煞譃槠胀ê凸鈱W(xué)白片兩種。普通白片的主要組成為鈉鈣硅酸鹽，折射率為1.51，可見光的透光率為89%以上，可吸收280nm以下的紫外線。光學(xué)白片的主要組成為鈉鈣硅酸，折射率為1.531，阿貝數(shù)60.5，透光率在91%以上，防紫外線性能**差。 </p> <p> 克羅克斯鏡片（Crookes） </p> <p> 由英國人威廉.克羅克斯于1914年發(fā)明，故命名為克羅克斯鏡片，簡稱克斯片。克斯片分為普通和光學(xué)克斯片兩種。普通克斯片簡稱光克片，是在鋇冕玻璃成分中添加微量 </p> <p> 的氧化鈰、氧化釹和氧化鐠等物質(zhì)，使鏡片有明顯的雙色效應(yīng)，即在白熾燈光下呈淺紫紅色，在日光燈下呈淺青蘭色，能吸收340nm以下的紫外線，折射率為1.523，透光率為87%以上。 </p> <p> 光致變色鏡片 </p> <p> 簡稱變**。是在無色或有色光學(xué)玻璃成分中添加鹵化銀等化合物，使鏡片能在紫外線照射時分解成銀和鹵素原子，鏡片顏色由淺變深。反之，當(dāng)光線變暗時，銀和鹵素重新又結(jié)合成無色的鹵化銀，使鏡片又回到原來無色或有基色的狀態(tài)。變色鏡片有茶變和灰變兩種，其特點(diǎn)是既可矯正視力，又可作為太陽眼鏡，適合野外配戴廣東批發(fā)彩鍍鏡片面板批發(fā)光致變色材料大多是灰色和棕色的，俗稱灰變和茶變，其它的顏色也可以通過專門的工藝達(dá)到。所有的眼鏡片。</p><div

2、涼熱感：用舌尖輕輕舔鏡片，涼爽感較強(qiáng)是天然水晶，舔后涼即變溫的是仿造品。 </p> <p> 3、硬度：天然水晶硬度大，一般灰塵不易劃傷其表面，若發(fā)現(xiàn)鏡片上有輕微細(xì)小的劃痕，便有贗品之嫌。 </p> <p> 4，天然水晶有雜質(zhì),有石紋,色澤沒有人造的白.人造的基本上沒有雜質(zhì) </p> <p> 5，天然水晶片握在手中始終是涼的,而人造的就會變暖.3天然的水晶鏡片有瑕疵,那兩塊偏光鏡片夾住看的話就會看的到.做眼鏡的叫"霞"還有天然的是有一定的彎度的 </p> <p> 6，水晶石的硬度是7度，可在玻璃和一般金屬上隨意劃出痕跡，而仿制品則達(dá)不到這樣高的硬度 </p> <p> 7，水晶石熔點(diǎn)為1713攝氏度，放在火爐中鍛燒后再放人冷水中仍不炸裂；而仿制品無固定熔點(diǎn)，加熱至高溫后放人水中立即炸裂。 </p><p style="text-indent:25px">PC鏡片定義：一般的樹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度也會變形，不適合高濕熱場合。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。對屈光異常引起的兒童斜視和伴有***的屈光異?；颊?，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。現(xiàn)代流行者強(qiáng)調(diào)，眼睛要有與時代人的面部化妝及服飾的和諧，反映社會階層高、學(xué)問高雅、時尚等象征。亞克力UV打印亞克力非常環(huán)保，能夠反復(fù)的進(jìn)行利用。</p><div

1990年又生產(chǎn)出了含鑭元素的鏡片，折射率為1.8，阿貝數(shù)為34； </p> <p> n 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。 </p> <p> n 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，其實(shí)實(shí)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。例如ABS的易加工特性和PC的優(yōu)良機(jī)械特性和熱穩(wěn)定性。深圳鏡片面板切割</p><p
