二向色型濾光片（顏色分離濾光片）可用于隔離特定范圍的可見光譜，少量應用于顏色增補以及影印機中的顏色平衡。該類型濾光片在將入射能分為兩束或更多的光束應用也發揮著很大的作用，下面的光譜圖反映的光譜曲線是在正入射的情況下得到的，但是在其他應用中，例如顏色的結合中，入射角為45度也是可取的。GeneralSpecificationsSizeTolerance:+0.0mm/-0.25mmThickness:1.0mm 0.25mmMinimumClearAperture:95%ofO.D.SubstrateMaterial:SodaLimeGlassFlatness:3to5waveper25mmParallelism:3ArcminutesorbetterSurfaceQuality:80/50PerMIL-O-13830BCoatingQuality:40/20PerMIL-O-13830BHumidityandAbrasion:PerMIL-C-675AMaxOperatingTemperature:+100 CMechanical:Notmountedinmetalholders (1)coloradditivefiltters（增色濾光片）A、典型光譜圖：B、選型表：紅光增色濾波片選型表：Filtertype25mm 50mm 50mmsq.Redadditivefilter585FD62-25585FD62-50585FD62-50S 綠光增色濾波片選型表：Filtertype25mm 50mm 50mmsq.Greenadditivefilter540FD66-25540FD66-50540FD66-50S 藍光增色濾波片選型表：Filtertype25mm 50mm 50mmsq.Blueadditivefilter505FD64-25505FD64-50505FD64-50S （2）colorsubtractivefilters:（減色濾光片）A、典型光譜圖： B、選型表：青色減色濾光片Filtertype25mm 50mm 50mmsq.Cyansubtractivefilter590FD24-25590FD24-50590FD24-50S 洋紅減色濾光片Filtertype25mm 50mm 50mmsq.Magentasubtractivefilter550FD26-25550FD26-50550FD26-50S 黃色減色濾光片Filtertype25mm 50mm 50mmsq.Yellowsubtractivefilter520FD22-25520FD22-50520FD22-50S （3）reflectiblefilters:（反射濾光片）A、典型光譜圖： B、選型表：紅色反射濾光片Filtertype25mm 50mm 50mmsq.Redreflectivefilter580FD70-25580FD70-50580FD70-50S藍色反射濾光片Filtertype25mm 50mm 50mmsq.Bluereflectivefilter475FD68-25475FD68-50475FD68-50S
