一、彩色濾光片是什么

彩色濾光片（Color filter）是一種表現(xian)顏(yan)色(se)(se)(se)的(de)(de)光(guang)(guang)(guang)學(xue)濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)，它可以精確選擇欲通過的(de)(de)小范圍波(bo)段(duan)光(guang)(guang)(guang)波(bo)，而反(fan)射掉其他不(bu)希望通過的(de)(de)波(bo)段(duan)。彩色(se)(se)(se)濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)通常安裝在光(guang)(guang)(guang)源的(de)(de)前方，使人(ren)眼可以接收到飽和的(de)(de)某(mou)個顏(yan)色(se)(se)(se)光(guang)(guang)(guang)線。有紅(hong)外濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)，綠色(se)(se)(se)，藍(lan)色(se)(se)(se)等。與(yu)UV濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)，VD濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)相比，凡是帶色(se)(se)(se)的(de)(de)濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)之(zhi)總(zong)稱。如反(fan)差濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)、分色(se)(se)(se)用濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)、LB濾(lv)光(guang)(guang)(guang)片(pian)(pian)(pian)(pian)(pian)等。

二、彩色濾光片的作用

彩(cai)色濾(lv)光(guang)(guang)片(pian)用途包括通(tong)過選色通(tong)帶(dai)及顯(xian)(xian)示(shi)(shi)(shi)(shi)器(qi)(qi)的(de)(de)最大輸出功率對單色顯(xian)(xian)示(shi)(shi)(shi)(shi)器(qi)(qi)（如VF（Vacuum Fluorescent）真空熒光(guang)(guang)顯(xian)(xian)示(shi)(shi)(shi)(shi)器(qi)(qi)、EL（Electroluminescent）電熒發光(guang)(guang)顯(xian)(xian)示(shi)(shi)(shi)(shi)器(qi)(qi)、LED發光(guang)(guang)二極管(guan)(guan)顯(xian)(xian)示(shi)(shi)(shi)(shi)器(qi)(qi)）進行反(fan)差增強。寬帶(dai)濾(lv)光(guang)(guang)片(pian)用來提高光(guang)(guang)學掃描儀和紅、黃、琥珀色發光(guang)(guang)二極管(guan)(guan)顯(xian)(xian)示(shi)(shi)(shi)(shi)器(qi)(qi)的(de)(de)反(fan)差及性能。中密度三槽型(xing)濾(lv)光(guang)(guang)片(pian)及極化鏡通(tong)過減少內部反(fan)射并在顯(xian)(xian)示(shi)(shi)(shi)(shi)器(qi)(qi)輸出功率及背景之間產生一個較大的(de)(de)變(bian)量從(cong)而(er)增強液晶(jing)顯(xian)(xian)示(shi)(shi)(shi)(shi)器(qi)(qi)（LCD）的(de)(de)反(fan)差。
