APO Plan - Apochromatic Microscope Objectives
Providing diffraction-limited focusing across the entire visible spectrum for demanding applications such as fluorescence microscopy, flow cytometry, and DNA sequencing.
APO Plan objectives eliminate chromatic dispersion focusing errors. They feature a state-of-the-art apochromatic (color-corrected) design with sub-wavelength surface accuracy on all the lens surfaces to deliver the highest performance for a glass objective.
APO Plan – Some Key Details
Get high magnification and hence image resolution, without sacrificing wide field of view, thanks to the apochromatic design.
