If I understand well, the last image is from the Oly. It shows a very little CA in the secondary spectrum, and the the one with high CA in the primary spectrum (orange-blue) is from the nikon, isn't it?
If so, there is something wrong, the nikon CF is spected to work OK whith the CF eyepiece. In the first image the barrel distorsion is very high
I don't have the answer nor this equipment, but I would proceed trying to isolate the problem:
- Repeat the test (If I was you, I would first suspect my own error changing the lenses, but I have a
very bad head)
- Do the same test with other objective pair, for exemple the 10X
- remove all the other optical components: intermediate tube (this 1.25X...), DIC slider...
- remove the microscope head and couple the camera with a bellows trying to set the tube lengh (between the objective shoulder and the sensor) to 150mm as most acurate as you can.
- Is the camera image in your setup parfocal with your image trough the viewing eyepieces?. Is it sharp at the same focusing points whith both photoeyepieces?
Be aware that this high NA objectives are very sensitive to the tube lengh.
- I think that the Oly NFK is not designed to work at the same tube lengh than the viewing eyepieces, perhaps the nikon one would work at a different distance: if you focus the microscope with a 10X objective and change the photoeyepiece for an viewing one, is it still focused?
- Ask to do this last test to a member that uses a nikon scope whith this kind of optics
if nothing works, send me all the optics as a Christmas gift
