</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*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。 </p><p>

</p> <p> 光線反射 </p> <p> 光線在鏡片表面產(chǎn)生折射的同時(shí)，也會產(chǎn)生反射現(xiàn)象。光線反射會影響鏡片的清晰度，而且在鏡片表面會產(chǎn)生干擾性反射光。通常，鏡片材料的折射率越高，因反射而損失的光線就越多。當(dāng)然，對于干擾性反射光可以通過在鏡片表面鍍多層減反射膜而相應(yīng)抵消。 </p> <p> 光線吸收：材料的本身吸收光的特性會減少鏡片的光線透過率，這部分的光量損失對于非染色眼鏡片是可以忽略的，但如果為染色或變色鏡片，光的吸收量會很大，這也是此類鏡片的設(shè)計(jì)目的。眼鏡片的光線吸收通常指材料內(nèi)部的光線吸收，可通過鏡片前、后表面吸收光線的百分比表示。例如，30%的光線吸收相當(dāng)于30%的光通量在鏡片內(nèi)部的減少。材料的光線吸收遵循郎伯(Lambert′s?Law)定律，它根據(jù)鏡片的不同厚度呈**性的變化這一現(xiàn)象是通過在材料中混合光致變色物質(zhì)的分子而完成。觀瀾pc鏡片面板切割</p><p

作為光學(xué)材料，水晶的比較大優(yōu)點(diǎn)是硬度大，制成的鏡片不易磨損。在本世紀(jì)20－30年代曾流行一時(shí)。因其制成的鏡片經(jīng)久耐用，又因其價(jià)格十分昂貴，常常留傳給下一代。 </p> <p> 在民間有：“水晶養(yǎng)目”之說。 </p> <p> 水晶的主要成分是SiO2，是一種天然透明礦物質(zhì)。 </p> <p> （1）水晶對紅外線、紫外線的吸收率差。 </p> <p> 對紫外線的吸收率*為14.5％，而玻璃對紫外線的吸收率是52％，目前加入U(xiǎn)V材料的樹脂鏡片對紫外線的吸收率已高達(dá)到90％以上. </p> <p> （2）天然水晶常含有雜質(zhì)，密度不均勻，會出現(xiàn)氣泡和條紋而產(chǎn)生雙折射現(xiàn)象，從而影響視力。 </p> <p> 由此可見，水晶不但不具有養(yǎng)目的作用，其對紫外線的高透過率是對眼睛有害的。在科學(xué)技術(shù)飛速發(fā)展的***，新的光學(xué)材料樹脂制作的眼鏡片，無論其光學(xué)性能、安全性能、防止有害射線保護(hù)眼睛的性能都遠(yuǎn)遠(yuǎn)優(yōu)于水晶深圳玻璃鏡片面板**膠</p></p><br /><p>文章來源地址:
