The narrow-band pass filter constituent with Ta_2O_5 and SiO_2 multilayers were prepared by dual ion-beams sputtering technology and the thickness of films was controlled with deposited time. The basic principle of dual ion-beams sputtering technology, the band pass filter design and the deposited techniques was present. The long wave pass (LWP) filter on K9 glass and the short wave pass (SWP) filter on colored glass were deposited, respectively. The optical performance of the narrow-band pass filter constituent with LWP and SWP was characterized by spectrophotometer. It is obvious that ion-beams sputtering technology can be used to prepare narrow-band pass filter.
