<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。??2）色散系數：阿貝數。 </p> <p> 由光波引起的折射率變化會使白光根據不同的折射產生色散現象。事實上，波長越短，折射率越高，可見光的折射從光譜的紅光區(qū)延伸到藍光區(qū)。材料的色散能力可以由阿貝數描述，在歐洲、日本規(guī)定用e線，在美國等其他國家規(guī)定使用d線。 </p> <p> 阿貝數與材料的色散力成反比，鏡片材料規(guī)定的范圍通常從30-60，數值越大即表示色散越少。一般而言，折射率越高，色散力越大，而阿貝數就越低。盡管所有鏡片都存在色散，但在鏡片中心，這個因素可以被忽略，只有在用高色散材料制造的鏡片周邊部，色散現象才易被察覺。在這種情況下，色散現象所表現的是離軸物體邊緣帶有彩色條紋 </p><p> 鏡片材料的基本分類 </p> <p> 鏡片材料采用透明的介質，主要分為無機和有機二大類。在我們的日常生活還會碰到一種天然介質水晶鏡片，這是用石英礦磨制成的鏡片。古代有水晶能養(yǎng)顏明目的說法，但事實上水晶的主要成分是二氧化硅（sio2），比較大優(yōu)點是硬性度高且不易受潮，但紫外線及紅外線的透過率較高，而且水晶中密度不均勻，含雜質，有條紋及氣泡等到產生，會形成雙折射現象，從而影響視力。無機材料--玻璃，玻璃是非常特殊的不定型材料，在常溫下呈現固體，堅硬但易碎，在高溫下具有粘性。玻璃沒有固定的化學結構，因而沒有確切的熔點。隨著溫度的上升，玻璃材料會變軟、粘性增加，并逐漸由固體變?yōu)橐后w，這種逐漸變化的特性我們稱之為"玻璃狀態(tài)"。這一特性意味著玻璃在高溫時可以被加工和鑄型。玻璃材料制成的鏡片具有良好的透光性、表面拋光后更加透明的優(yōu)點 1962年出現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; max-height: 320px;" alt="沙井cnc手機鏡片面板加工,鏡片面板"

玻璃鏡片的主要原料是光學玻璃。其折射率比樹脂鏡片高，因此在同樣度數情況下，玻璃鏡片要比樹脂鏡片薄。玻璃鏡片的透光率和機械化學性能都比較好，有恒定的折射率、理化性能穩(wěn)定。沒有顏色的鏡片稱光學白托（白片），有**中的粉紅片稱克羅克賽鏡片（紅片）?？肆_克賽鏡片能吸收紫外線、對強光略有吸收作用。 </p> <p>
