I bought a Zeiss GFL Pol mikroskope which needed cleaning, lubricating, centering and other maintenance.
I partially dismounted the micro and macro gears, cleaned as much as possible and remounted again.
I am going now to center the scope.
To do this I dismounted the analyzer holder, and placed a simple straight tube (no other optics inside) in its place, equipped with a non centerable objective and a simple ocular).
I placed a proper specimen on the rotating table, and tried to make the tube coaxial with the table, rotating the three screws available for centering it.
Unfortunately it was not possible. To center the tube I should displeca it more than possible, and at the best the table axis seems located in the upper left quadrant of the ocular field.
Obviously I will try again, but I would like in the meantime to ask you the following:
The rotating table of Zeiss GFL Pol has some centering screws, may be hidden somewhere, or cannot be centered and must be taken as the reference axis for all the equipment?
Thanks to everybody for the attention.
Regards,
Salvatore Previtera
