WebThe sample itself is part of the optical pathway and can introduce spherical aberration as seen in Fig 1. To compensate, it is necessary to use immersion oils of varying refractive index (RI) to introduce an equal and opposite spherical aberration and bring the sample back into optimal focus and contrast. This is in essence very simple WebMIT - Massachusetts Institute of Technology
