Andover分(fen)色(se)濾(lv)光(guang)片
二向(xiang)色(se)濾(lv)光(guang)片（分(fen)色(se)濾(lv)光(guang)片）用於需(xu)要隔離可見(jian)光(guang)譜(pu)的某些區域的各種(zhong)應用(yong)中(zhong)。壹(yi)些較常(chang)見(jian)的應用(yong)是用於(yu)彩色(se)放(fang)大器(qi)和(he)復(fu)印(yin)機(ji)作為光(guang)平(ping)衡(heng)濾(lv)光(guang)器(qi)。它們(men)在任(ren)何(he)可能需(xu)要將(jiang)入(ru)射能量(liang)分(fen)成兩(liang)個(ge)或多個(ge)光(guang)束(shu)的應用(yong)中(zhong)也非(fei)常(chang)有(you)用。以下光(guang)譜(pu)曲線以垂(chui)直(zhi)入(ru)射方(fang)式顯(xian)示，但是對於許(xu)多應用(yong)，例(li)如組(zu)合(he)顏色(se)，可能希望以45°入(ru)射角(jiao)以反射(she)模(mo)式使用(yong)它們(men)。
在這(zhe)些過濾(lv)器(qi)中(zhong)使用的所(suo)有(you)塗(tu)層材料(liao)都(dou)產(chan)生堅(jian)硬，耐(nai)用的介電(dian)薄膜(mo)，其沒(mei)有(you)隨(sui)著使(shi)用年(nian)限和(he)使用(yong)而(er)降(jiang)低的跡象(xiang)。與使(shi)用時會(hui)褪(tui)色(se)的有機(ji)染料(liao)或明(ming)膠(jiao)類型(xing)不(bu)同，這(zhe)些過濾(lv)器(qi)非(fei)常(chang)穩(wen)定，不(bu)會隨(sui)著時間(jian)的推(tui)移而(er)損(sun)失(shi)任何效率(lv)。這(zhe)些過濾(lv)器(qi)也(ye)可以成套(tao)使(shi)用(yong)。過濾(lv)器(qi)也(ye)可以安裝(zhuang)在螺(luo)紋(wen)環中(zhong)。
可根(gen)據要(yao)求(qiu)提供(gong)定制尺寸，基(ji)材和光(guang)譜(pu)特(te)性(xing)。
