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)的(de)光(guang)(guang)(guang)學濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)，它(ta)可以精確選(xuan)擇欲通過(guo)的(de)小(xiao)范圍波段光(guang)(guang)(guang)波，而反(fan)(fan)射掉(diao)其他不希望通過(guo)的(de)波段。彩色(se)濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)通常安裝在光(guang)(guang)(guang)源的(de)前方，使人眼可以接收到(dao)飽(bao)和的(de)某(mou)個顏(yan)色(se)光(guang)(guang)(guang)線。有紅外濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)，綠色(se)，藍色(se)等。與UV濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)，VD濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)相比，凡是帶色(se)的(de)濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)之總稱。如反(fan)(fan)差濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)、分色(se)用濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)、LB濾(lv)(lv)光(guang)(guang)(guang)片(pian)(pian)等。

二、彩色濾光片的作用

彩色(se)濾(lv)光(guang)(guang)(guang)片(pian)用(yong)途包括通過選色(se)通帶及顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)的最大(da)(da)輸出功率(lv)對單色(se)顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)（如VF（Vacuum Fluorescent）真空熒(ying)光(guang)(guang)(guang)顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)、EL（Electroluminescent）電熒(ying)發(fa)光(guang)(guang)(guang)顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)、LED發(fa)光(guang)(guang)(guang)二(er)極(ji)管顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)）進行反差增強。寬帶濾(lv)光(guang)(guang)(guang)片(pian)用(yong)來(lai)提高光(guang)(guang)(guang)學掃描儀和紅、黃、琥(hu)珀色(se)發(fa)光(guang)(guang)(guang)二(er)極(ji)管顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)的反差及性(xing)能。中密度(du)三槽型濾(lv)光(guang)(guang)(guang)片(pian)及極(ji)化(hua)鏡通過減少(shao)內部反射并在(zai)顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)輸出功率(lv)及背景之間產生一個較大(da)(da)的變(bian)量從(cong)而增強液晶顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)（LCD）的反差。

寬帶濾光片（黃色(se)、琥珀(po)色(se)、紅(hong)色(se)）

通帶(dai)濾(lv)光片（藍色、綠色）

定制彩色(se)濾(lv)光(guang)片（三槽型濾(lv)光(guang)片）

極化(hua)鏡（線性或圓形）

Band Rejection：帶阻近紅外線濾光片(pian)

夜視濾光片

Dontech彩色濾光片由光(guang)學襯底制成，如(ru)丙烯酸(suan)、聚碳酸(suan)酯和玻璃(li)。通過堆積襯底與吸水性材料(liao)或(huo)進(jin)行薄(bo)膠片鍍膜可(ke)進(jin)行著色(se)；這些鍍膜可(ke)通過或(huo)阻止可(ke)見(jian)光(guang)、紅(hong)外和近紅(hong)外光(guang)譜的特殊波長。
