6．面板鏡片模鑄法：傳統(tǒng)漸進片采用漸進片坯料加工，前表面為漸進面，后表面為球面或托力克面。自由曲面：采用CNC數(shù)控機床在鏡片表面直接磨削出復雜光學曲。采用單點磨削系統(tǒng)在鏡片表面直接磨削出復雜光學曲面的技術稱為自由曲面技術（Free-Form）高精度鉆石切割工具和特殊的特殊的, </p> <p> 鏡片的膜層結構：頂膜，減反射膜，加硬膜：由于密度低，樹脂鏡片非常輕而且配戴非常舒適 </p> <p> ? 但卻有個缺點：由于表面較軟，易于擦傷。為了修正這個缺點，樹脂 </p> <p> 鏡片會被選擇使用加硬保護膜層 </p> <p> ?加硬膜層的優(yōu)點：能較長時間保持光學品質和外觀 </p> <p> 加硬的方式：浸泡式，真空沉淀法 </p> <p> <br />

光學性質是材料的基本性質，與鏡片在日常生活中所見到的各種光學現(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：通過鏡片的光線會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：透明媒質的折射率是光線在真空中的速度c與在媒質中的速度v的比值， </p> <p> n=c/v。該比值沒有單位并且總是大于1。折射率反映媒質的折射能力，折射率越高，從空氣進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)進行計算，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、折射光線構成。計算公式：?sin?i=n?sin?r????由于透明媒質的光速隨著波長而變化，所以折射率的值總是參考某一特定波長 </p> <p> 表示：在歐洲和日本，參考波長為e線546.07nm(汞--綠光譜線)，但是在美國等其它 </p> <p> 國家則是d線587.56nm(氦--黃光譜線)。但這個區(qū)別并沒有造成實際影響，因為它的 </p> <p> 區(qū)別**反映在折射率值的第三位小數(shù)上。寶安pet鏡片面板</p></p><br /><p>文章來源地址:
