光致變色樹脂材料： </p> <p> ***代光致變色樹脂鏡片出現(xiàn)在1986年，但是直到1990年***代Transition鏡片面市后，它才真正開始普及。一種新型的光致樹脂鏡片于1993年投放市場(chǎng)，這種鏡片采用樹脂材料作片基，用滲透法在鏡片的凸面滲透了一層光致變色材料，然后再鍍上一層抗磨損膜，起保護(hù)和耐磨作用。這項(xiàng)工藝技術(shù)可以使鏡片的變色不會(huì)隨屈光度數(shù)的加深而出現(xiàn)鏡片**與周圍深淺不一的情況，彌補(bǔ)了玻璃變色的不足。再加上片基是樹脂材料，質(zhì)輕且抗沖擊性強(qiáng)，所以這種鏡片特別適合用于各種屈光不正者使用 </p> <p> 光致變色樹脂鏡片的組合物: </p> <p> １．在所述單體混合物中加入抗氧劑、受阻胺、紫外線吸收劑、光穩(wěn)定劑及聚合調(diào)節(jié)劑等，以提高光致變色染料的壽命。 </p> <p> ２．在所述單體混合物中加入內(nèi)增塑劑大幅度提高鏡片的抗沖擊性。 </p> <p> ３．加入環(huán)氧及胺基單體**改進(jìn)鏡片的膜層牢度。 </p><p> 光學(xué)玻璃鏡片的分類。 </p> <p> 無色玻璃鏡片 </p> <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(jiǎn)稱克斯片?？怂蛊譃槠胀ê凸鈱W(xué)克斯片兩種。普通克斯片簡(jiǎn)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(jiǎn)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(shí)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(shí)，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，適合野外配戴光學(xué)鏡片的特點(diǎn)有哪些。</p><div

即折射率、透光率和色散系數(shù)等 </p> <p> A、折射率是決定鏡片屈光度的常數(shù)之一。 </p> <p> B、色散系數(shù)是衡量鏡片成像清晰度的重要指標(biāo) 。 </p> <p> C、透光率是視物清晰度的重要指標(biāo)，無色光學(xué)玻璃對(duì)可見光的透光率應(yīng)在92%以上。透光率越高，視物就越清晰。 </p> <p> （4）機(jī)械性能 </p> <p> 主要包括比重（密度）、硬度、表面張力和彈性系數(shù)等。 </p> <p> 比重和硬度在眼鏡玻璃中是極其重要的參數(shù)。一般光學(xué)玻璃的比重均比較大，比重和折射率有一定的關(guān)系。折射率越大，比重也就越大，鏡片的重量就增加。光學(xué)眼鏡片的表面要求有一定的硬度，硬度不僅影響使用壽命，而且也直接影響鏡片的研磨加工質(zhì)量和速度。它的基本原則是使普通的玻璃（包括塑料光致變色材料）在紫外線輻射的影響下顏色變深.鳳崗pc油漆鏡片面板哪家好</p><p
