A new dichromic interference filter was used as the excitation filter in colour and black-and-white fluorescein angiography of the human fundus. The interference filter transmits light shorter than 490 nm (blue) and longer than 640 nm (red). In colour photography the red light shows the topography of the fundus. In black-and-white photography, the red light is prevented from reaching the fundus by an additional absorption filter used together with the interference filter. These two comprise the excitation filter, which eliminates the pseudo-fluorescence from black-and-white angiograms.
一种新型双色干涉滤光片被用作人眼底彩色和黑白荧光血管造影的激发滤光片。该干涉滤光片透射波长小于490纳米（蓝光）和大于640纳米（红光）的光。在彩色摄影中，红光显示眼底的地形。在黑白摄影中，通过与干涉滤光片一起使用的附加吸收滤光片，可防止红光到达眼底。这两者构成激发滤光片，可消除黑白血管造影中的假荧光。
