A microscope objective with incredible brightness and the highest level of aberration correction across the entire field of view— the ideal choice for critical digital imaging. The CFI Plan Apochromat VC series are top performance objectives with perfect correction of chromatic aberrations in the visible light range and excellent resolution throughout the field of view. They are the perfect choice for multi-stained, fluorescence specimens and when using brightfield and DIC techniques. In addition to the correction range of the conventional Apochromat series (435-660nm), axial chromatic aberration has been corrected up to the violet range (405nm), making these objectives highly effective PA-GFP, as well as other photo-activation and photo-conversion proteins that activate at 405nm. CFI Plan Apochromat VC optics are an ideal choice for critical confocal work as well.
