Re: Interferometer question

Hi Uwe,

Now my question ist, what radius matches (76,51) - is it 25mm
from the optical axis _or_ is it halfways on the surface, which means
a radius (slightly) _larger_ than 25mm.

There is possibly distortion inside the interferometer, and it's almost sure
that the answer does also depend on the setting of the internal zoom
objective.
You asked a very good question, it's one of these interesting questions that
were never answered by the manufacturers. Another of these questions is
about re-tracing errors.
Please contact me by private mail.
