Hello
I have som questions about the Durst G139
To all who have a thirst vacuum table:
Can it be that the table area in the middle drops about about 1 mm? Has the table been "overvacuated"? Or is this intentional (a kind of correction due to Field Curvature)?
To all which use the "Grane / Grahal" image stage as a negative holder: What is the correct geometry and the thickness of the glasses? Appended is a sample picture which I found. It is not clear whether to see the original glasses in the picture ...
Thank you all for your support
