Andover吸收中性密度濾光片
發(fā)布日期： 2025-04-09
訪問(wèn)量： 1408
Andover吸收中性密度濾光片，吸收式ND濾光片的**之處在于它們采用增透膜涂層以減少表面反射。這使得它們能夠堆疊而不用擔(dān)心由于多次反射造成的損失和偽影。

Andover吸收中性密度濾光片

由于具有**小化背反射和散射光的能力，吸收中性密度（ND）濾光片是校準(zhǔn)的理想選擇。與金屬類(lèi)型相反，吸收型濾光器通過(guò)吸收基板內(nèi)的光來(lái)實(shí)現(xiàn)其光密度。因此，厚度是不透明度的關(guān)鍵決定因素。由于其吸收質(zhì)量，這些濾波器僅適用于低功率應(yīng)用。

Andover吸收式ND濾光片的**之處在于它們采用增透膜涂層以減少表面反射。這使得它們能夠堆疊而不用擔(dān)心由于多次反射造成的損失和偽影。

請(qǐng)注意，我們所有的Absorbing ND濾鏡都是成套的，包括硬木儲(chǔ)物盒。
