由光波引起的折射率變化會使白光根據(jù)不同的折射產(chǎn)生色散現(xiàn)象。事實(shí)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(lán)光區(qū)。材料的色散能力可以由阿貝數(shù)描述，光明pc亞克力鏡片面板切割，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(shù)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(shù)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(shù)就越低。盡管所有鏡片都存在色散，光明pc亞克力鏡片面板切割，但在鏡片中心，這個(gè)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(xiàn)象才易被察覺。在這種情況下，光明pc亞克力鏡片面板切割，色散現(xiàn)象所表現(xiàn)的是離軸物體邊緣帶有彩色條紋比重高（密度大）：即單位體積所含分子數(shù)量多，因此在配戴時(shí)感覺沉重。光明pc亞克力鏡片面板切割</p><div

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(fù)合光）在經(jīng)過透明介質(zhì)時(shí)，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>
