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.
