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。可*使用在汽車內(nèi)部零件、商務機器、通信器材、家電用品及照明設備上。深圳批發(fā)彩鍍鏡片面板切割</p><div style="width:100%;text-align: center;"><img style="max-width:

（1）普通玻璃材料（1。5和1。6）：折射率為1.523的冕牌玻璃是傳統(tǒng)光學鏡片的制造材料，其中60%~70%為二氧化硅，其余則由氧化鈣、鈉和硼等多種物質(zhì)混合。有時也將折射率為1.6的鏡片劃歸普通鏡片。 </p> <p> （2）高折射率玻璃材料：經(jīng)過多年的研究，鏡片制造商已經(jīng)找到了在提高材料折射率的同時又保持低色散的方法，即在玻璃中加入新的化學元素。????早在1975年就生產(chǎn)出了含鈦元素的鏡片，折射率為1.7，阿貝數(shù)為41；15年之后又生產(chǎn)出了含鑭元素的鏡片，折射率為1.8，阿貝數(shù)為34；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。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。實際上，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。深圳批發(fā)彩鍍鏡片面板切割當紫外線輻射減弱，移動電子離開銀原子返回氯原子，鏡片逐漸恢復了原先的清澈狀態(tài)。</p><div

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> 鏡片面板 </p> <p> 1.鏡片材料的歷史 </p> <p> 1.歷史： </p> <p> 1636年～1940年玻璃是生產(chǎn)鏡片的主要材料 </p> <p> 1975年折射率為1.7的玻璃鏡片 </p> <p> 1983年折射率為1.6的玻璃鏡片 </p> <p>

熱性質(zhì)主要包括：1、熱傳導系數(shù)。2、比熱：物體溫度每升高一攝氏度所需的熱量與相同質(zhì)量的水溫每升高一攝氏度所需的熱量的比值。3、線性膨脹系數(shù)：預先設定的溫度范圍。4、熔點：物理常數(shù)。5、沸點。?6、鏡片的應力溫度。 </p> <p> <br /> </p> <p> 電性質(zhì)表示了材料電磁波和電效應的特性，由物理定律決定，有時需將鏡片的光學性質(zhì)與電性質(zhì)聯(lián)系。通常材料制造進需考慮以下參數(shù)：1、介電強度；2、預定頻率下的介電損耗系數(shù)。使材料對太陽光強度作出反應的一種性質(zhì)。深圳批發(fā)彩鍍鏡片面板切割</p><p

style="text-indent:25px">PC面板：專業(yè)名稱為聚碳酸酯（Polycarbonate）板，縮寫為PC板，是一種無色透明的無定性熱塑性材料，其化學性質(zhì)表現(xiàn)為耐油、耐酸、不耐強堿，不耐紫外線，故不適于室外使用；物理性能為無色透明、耐熱、抗沖擊，耐磨性能比PMMA差，需對其表面進行改良性處理,即納米硬化(hard coating)處理。硬化后表面硬度可達到HB-1H，且具有防刮花、耐磨擦、防霧化、防眩光、防靜電、防指紋的性能，可根據(jù)要求對板材進行單面或者雙面硬化處理。因PC板具有良好的機械性能，故是制造通訊產(chǎn)品、數(shù)碼產(chǎn)品、***電器產(chǎn)品面板鏡片之理想材料。防指紋硬化PC板按使用要求可分為普通級、印刷級、光學級三種，普通級適用于手機按鍵、數(shù)碼攝像頭、標牌銘板、電器面板、儀器儀表面板、視窗面板、薄膜開關(guān)等；印刷級適用于手寫觸摸屏、***電器面板銘牌等；光學級主要應用于手機鏡片、液晶顯示屏、數(shù)碼鏡片、光學鏡片等。深圳批發(fā)彩鍍鏡片面板切割</p></p><br
