中性密度(du)（ND）濾波(bo)器可用(yong)於許(xu)多(duo)應(ying)用(yong)，例(li)如用於(yu)寬(kuan)帶光譜(pu)源的(de)衰(shuai)減(jian)器，用於光平(ping)衡應(ying)用(yong)的(de)部分反射(she)器以(yi)及(ji)用作(zuo)中性分束(shu)器。金屬型中(zhong)性密度(du)濾光(guang)器通過將金(jin)屬(shu)合金塗層沈(chen)積(ji)到特定(ding)類(lei)型的基板上(shang)來獲(huo)得(de)其(qi)光密(mi)度(du)，該基板由(you)感(gan)興(xing)趣的波(bo)長(chang)區域確定(ding)。使(shi)用Schott NG玻璃(li)生產(chan)吸收(shou)ND濾光(guang)片，並嚴格依賴(lai)玻(bo)璃(li)的吸收(shou)效果(guo)來獲(huo)得(de)所需(xu)的(de)衰(shuai)減(jian)水(shui)平(ping)。

光(guang)密(mi)度（OD）定(ding)義(yi)為透(tou)射(she)輻(fu)射(she)功(gong)率(lv)（T）的倒(dao)數的基數10的對數：
