Confocal microscopy
It follows that any chromatic or spherical aberration will seriously affect performance. 
Fluorescence microscopy

Light microscopy
The problem with the simple arrangement is that the distance between objective and eyepiece must be absolutely fixed, since spherical aberration can only be corrected for one position of the image.
