Plan Fluor Series Objectives

20x magnification, NA=0.5, working distance 2.2mm, flat-field semi-apochromatic correction, air medium, compatible with 0.17mm coverslips, balancing field of view and submicron resolution.

Applications:
For fluorescence imaging of cellular substructures (such as mitochondria, endoplasmic reticulum labeling), or multi-modal analysis (brightfield/fluorescence/DIC) of thin biological samples (single cells, ultra-thin tissues).
