Feature 1Parallel Optical Pathing: Biological microscope objective is parallel optical pathing, no included angle, correction of spherical aberration and sink aberration, the image formed is clearer and sharper, the field of view is wider than the ordinary achromatic objective. 2Low Magnification Lens: Achromatic objective lens adopts low magnification lens, with larger aperture, brighter imaging and larger field of view. 3Universal Lens: Microscope achromatic objective lens adopts universal 20.2mm standard RMS interface thread, with a wide range of compatibility, most professional biological microscopes can be used. 4Open Field of View: Microscope achromatic objective lens is more comfortable to view, the lens will not be injured, scratched, longer service life. 5Exquisite Workmanship: Microscope achromatic objective lens is well designed and exquisite workmanship. The objective lens is coated film, with high transmittance and refractive index, the image is brighter and clearer.Item Type: 195 Objective LensMaterial: Brass, stainless steel, optical glassUse: Widely used, threaded interface size for the international standard 20.2mm RMS size, most of the professional biological microscopes on the market can be usedSpecification: 10X .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x AchromaticObjectiveLens1 x StorageCanister
