由於具(ju)有(you)Z小(xiao)化背反(fan)射和(he)散(san)射光(guang)的(de)能力(li),吸收(shou)中性密(mi)度(ND)濾(lv)光(guang)片(pian)是校準的(de)理想(xiang)選擇。與金屬(shu)類型相反(fan),吸收(shou)型濾(lv)光(guang)器(qi)通過(guo)吸收(shou)基板(ban)內的(de)光來(lai)實(shi)現(xian)其(qi)光(guang)密(mi)度。因(yin)此(ci),厚(hou)度是不透明(ming)度的(de)關鍵決(jue)定(ding)因(yin)素。由於其(qi)吸(xi)收(shou)質量(liang),這些(xie)濾(lv)波(bo)器(qi)僅(jin)適用(yong)於低功(gong)率應用(yong)。
Andover吸收(shou)式(shi)ND濾(lv)光(guang)片(pian)的(de)*之處(chu)在於它們(men)采(cai)用(yong)增透膜塗(tu)層(ceng)以(yi)減(jian)少(shao)表面反(fan)射。這使(shi)得它們(men)能夠堆疊(die)而(er)不用(yong)擔(dan)心由於多次(ci)反(fan)射造(zao)成(cheng)的(de)損(sun)失(shi)和偽(wei)影。
請(qing)註(zhu)意,我們(men)所有(you)的(de)Absorbing ND濾鏡都是成(cheng)套的(de),包括硬木儲物盒。
