Nipkow Nyquist matching

Search the CONFOCAL archive at http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal We recently demo'd several spinning disk confocal systems.  For Nyquist matching of camera and objective, we saw two different solutions.  In one case, a lens was mounted between the scan head and the microscope so that both excitation and emission went through it.  In the other case, it was mounted between the scan head and the camera so only emission went through.  Can anyone comment on the relative merits of this design decision?  THanks- Dave

Putting 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.
