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(fā)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F(xiàn)iltertype25mm 50mm 50mmsq.Cyansubtractivefilter590FD24-25590FD24-50590FD24-50S 洋紅減色濾光片F(xiàn)iltertype25mm 50mm 50mmsq.Magentasubtractivefilter550FD26-25550FD26-50550FD26-50S 黃色減色濾光片F(xiàn)iltertype25mm 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F(xiàn)iltertype25mm 50mm 50mmsq.Redreflectivefilter580FD70-25580FD70-50580FD70-50S藍色反射濾光片F(xiàn)iltertype25mm 50mm 50mmsq.Bluereflectivefilter475FD68-25475FD68-50475FD68-50S
