一、彩色濾光片是什么

彩色濾光片（Color filter）是一(yi)種表(biao)現顏色(se)的(de)(de)(de)光(guang)(guang)(guang)(guang)學濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)，它可(ke)以精確選擇欲(yu)通過(guo)的(de)(de)(de)小范(fan)圍(wei)波(bo)段光(guang)(guang)(guang)(guang)波(bo)，而反射掉其他不希望通過(guo)的(de)(de)(de)波(bo)段。彩色(se)濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)通常安裝在光(guang)(guang)(guang)(guang)源(yuan)的(de)(de)(de)前方，使人(ren)眼可(ke)以接收到(dao)飽和的(de)(de)(de)某個顏色(se)光(guang)(guang)(guang)(guang)線(xian)。有紅外濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)，綠色(se)，藍色(se)等。與UV濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)，VD濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)相比，凡是帶色(se)的(de)(de)(de)濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)之總稱。如反差(cha)濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)、分色(se)用濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)、LB濾(lv)(lv)(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)等。

二、彩色濾光片的作用

彩色(se)(se)濾光(guang)(guang)(guang)(guang)片用途包括通過選色(se)(se)通帶及(ji)顯(xian)示(shi)器(qi)(qi)(qi)的最(zui)大(da)輸出(chu)功(gong)率對單色(se)(se)顯(xian)示(shi)器(qi)(qi)(qi)（如VF（Vacuum Fluorescent）真空熒光(guang)(guang)(guang)(guang)顯(xian)示(shi)器(qi)(qi)(qi)、EL（Electroluminescent）電熒發光(guang)(guang)(guang)(guang)顯(xian)示(shi)器(qi)(qi)(qi)、LED發光(guang)(guang)(guang)(guang)二極管顯(xian)示(shi)器(qi)(qi)(qi)）進行反(fan)差增(zeng)強(qiang)。寬帶濾光(guang)(guang)(guang)(guang)片用來提高(gao)光(guang)(guang)(guang)(guang)學掃描儀(yi)和紅、黃、琥珀色(se)(se)發光(guang)(guang)(guang)(guang)二極管顯(xian)示(shi)器(qi)(qi)(qi)的反(fan)差及(ji)性能。中密度(du)三槽型濾光(guang)(guang)(guang)(guang)片及(ji)極化鏡(jing)通過減少(shao)內部(bu)反(fan)射并在顯(xian)示(shi)器(qi)(qi)(qi)輸出(chu)功(gong)率及(ji)背景之間(jian)產(chan)生一個(ge)較(jiao)大(da)的變量從而(er)增(zeng)強(qiang)液晶顯(xian)示(shi)器(qi)(qi)(qi)（LCD）的反(fan)差。

夜視濾光片

Dontech彩色濾光片由光學(xue)襯(chen)底制成(cheng)，如丙烯(xi)酸(suan)、聚碳(tan)酸(suan)酯和玻璃。通過(guo)堆積襯(chen)底與(yu)吸水性材料或進(jin)行(xing)薄膠片鍍(du)膜可(ke)進(jin)行(xing)著色；這些鍍(du)膜可(ke)通過(guo)或阻止可(ke)見(jian)光、紅(hong)外和近紅(hong)外光譜的特殊(shu)波長。
