一、彩色濾光片是什么

彩色濾光片（Color filter）是一種表現顏色(se)(se)的(de)光(guang)(guang)(guang)(guang)學濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)，它可(ke)以精(jing)確選擇欲通(tong)過的(de)小范圍波段光(guang)(guang)(guang)(guang)波，而反射掉(diao)其他不希望通(tong)過的(de)波段。彩色(se)(se)濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)通(tong)常安裝在光(guang)(guang)(guang)(guang)源的(de)前方，使(shi)人眼(yan)可(ke)以接收(shou)到飽(bao)和(he)的(de)某個(ge)顏色(se)(se)光(guang)(guang)(guang)(guang)線。有(you)紅(hong)外濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)，綠色(se)(se)，藍色(se)(se)等(deng)。與UV濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)，VD濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)相比(bi)，凡是帶(dai)色(se)(se)的(de)濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)之總稱。如(ru)反差濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)、分色(se)(se)用濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)、LB濾(lv)(lv)光(guang)(guang)(guang)(guang)片(pian)(pian)(pian)等(deng)。

二、彩色濾光片的作用

彩色(se)濾光(guang)(guang)(guang)片(pian)(pian)用途(tu)包(bao)括通(tong)過(guo)選(xuan)色(se)通(tong)帶及(ji)顯(xian)(xian)示(shi)器(qi)(qi)的最大輸出功率對單色(se)顯(xian)(xian)示(shi)器(qi)(qi)（如VF（Vacuum Fluorescent）真空(kong)熒光(guang)(guang)(guang)顯(xian)(xian)示(shi)器(qi)(qi)、EL（Electroluminescent）電熒發(fa)光(guang)(guang)(guang)顯(xian)(xian)示(shi)器(qi)(qi)、LED發(fa)光(guang)(guang)(guang)二(er)極管顯(xian)(xian)示(shi)器(qi)(qi)）進行反(fan)差(cha)增強(qiang)(qiang)。寬帶濾光(guang)(guang)(guang)片(pian)(pian)用來提高光(guang)(guang)(guang)學掃描儀和紅、黃、琥珀色(se)發(fa)光(guang)(guang)(guang)二(er)極管顯(xian)(xian)示(shi)器(qi)(qi)的反(fan)差(cha)及(ji)性(xing)能。中密(mi)度三槽型濾光(guang)(guang)(guang)片(pian)(pian)及(ji)極化鏡通(tong)過(guo)減少內部反(fan)射(she)并在(zai)顯(xian)(xian)示(shi)器(qi)(qi)輸出功率及(ji)背景之間產生(sheng)一個較大的變量從而(er)增強(qiang)(qiang)液晶(jing)顯(xian)(xian)示(shi)器(qi)(qi)（LCD）的反(fan)差(cha)。

Contrast Enhancement：反(fan)差增(zeng)強中密度濾光（灰色(se)、青銅色(se)）

寬帶(dai)濾光片（黃色、琥(hu)珀色、紅色）

通帶濾光片（藍色(se)、綠色(se)）

定制彩色(se)濾光片（三槽型濾光片）

極化鏡（線性或圓形(xing)）

Band Rejection：帶阻近紅外線濾光片
