http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocalPutting a lens between the scanhead and the microscope will change the
effective size of the pinholes as seen by the objective. Depending on
the objective you're using and the pinhole size this may be a good or a
bad thing.
Mounting the lens between the scanhead and the camera should affect only
the magnification of the image on the camera without changing anything else.
There are probably other differences between the two lens positions;
I'll leave comments on that for someone more knowledgeable than myself.
