中性密(mi)度（ND）濾(lv)波(bo)器(qi)可(ke)用於(yu)許(xu)多(duo)應(ying)用，例(li)如(ru)用於(yu)寬(kuan)帶(dai)光(guang)譜源的衰減器(qi)，用於(yu)光(guang)平(ping)衡應(ying)用的部(bu)分反射(she)器以(yi)及用作中性分束器(qi)。金屬(shu)型(xing)中性密(mi)度濾(lv)光(guang)器通過將(jiang)金屬(shu)合金塗(tu)層(ceng)沈(chen)積到(dao)特(te)定(ding)類型(xing)的基板(ban)上來(lai)獲(huo)得(de)其(qi)光(guang)密(mi)度，該(gai)基(ji)板(ban)由(you)感興(xing)趣(qu)的波(bo)長(chang)區域(yu)確定(ding)。使(shi)用Schott NG玻璃(li)生產(chan)吸(xi)收ND濾(lv)光(guang)片，並(bing)嚴格依賴(lai)玻璃(li)的吸(xi)收效果來獲(huo)得(de)所(suo)需(xu)的衰減水平(ping)。

光(guang)密(mi)度（OD）定(ding)義(yi)為(wei)透射(she)輻(fu)射(she)功率(lv)（T）的倒數的基數10的對(dui)數：
