一、彩色濾光片是什么

彩色濾光片（Color filter）是(shi)一種(zhong)表現顏(yan)色的光(guang)(guang)(guang)(guang)學濾光(guang)(guang)(guang)(guang)片(pian)，它可(ke)以精確選擇欲通(tong)(tong)過(guo)的小范圍(wei)波(bo)段光(guang)(guang)(guang)(guang)波(bo)，而反射掉其他不希望(wang)通(tong)(tong)過(guo)的波(bo)段。彩色濾光(guang)(guang)(guang)(guang)片(pian)通(tong)(tong)常安裝在光(guang)(guang)(guang)(guang)源的前方，使(shi)人眼可(ke)以接收到飽和的某個(ge)顏(yan)色光(guang)(guang)(guang)(guang)線。有紅外濾光(guang)(guang)(guang)(guang)片(pian)，綠色，藍色等(deng)。與UV濾光(guang)(guang)(guang)(guang)片(pian)，VD濾光(guang)(guang)(guang)(guang)片(pian)相比，凡(fan)是(shi)帶色的濾光(guang)(guang)(guang)(guang)片(pian)之總稱。如(ru)反差濾光(guang)(guang)(guang)(guang)片(pian)、分(fen)色用濾光(guang)(guang)(guang)(guang)片(pian)、LB濾光(guang)(guang)(guang)(guang)片(pian)等(deng)。
