精密设计制造的双胶合镜，由于它极小的色差和球差，在可见光谱范围内可以获得很好成象质量，为增加透过率，在表面镀增透膜，减少在系统中的散射，达到单片镜无法达到的成影效果。材料选择：各种光学玻璃可提供规格： 200mm以内的各种玻璃材质双胶合镜。(5)AchromaticDoubletLensEffectSophisticatedfabricateddoubletlens,withextremelysmallchromaticaberrationandsphericalaberration,cangeneratehighqualityimageswithinthevisiblelightspectrumandcanreducethelightscatteringinthesystemtoachieveaimagingeffectthatcannotobtainedbyasinglelens,duetoanantireflectioncoatingonthesurface.Material:variouskindsofopticalglassSpecifications:Doubletlensesmadeofvariousglassmaterialswithadiameterwithin200mm 联系人：麦小姐 13631883150 QQ:710371198
