Eyeglass lenses
....dass eine Fläche mit reduzierten Oberflächenunterschieden, insbesondere eine **kontinuierliche ableitbare Fläche**, erzielt wird.
Context: Patent on manufacturing eyeglass lenses. Something (sorry, have to be vague) is applied to the lens blank to even out surface differences to achieve a "continuous ????? surface. The purpose is to reduce stresses during/after processing the lens.
TIA

(not derivable, here: differentiable)
https://math.stackexchange.com/questions/1117323/the-definit...
From: https://en.wikipedia.org/wiki/Smoothness#Differentiability_c... : a continuously differentiable function is a continuous function whose derivative exists.
All lenses are continuously differentiable! It's not a functioning lens until this is achieved
There is some evidence for the use of "continuously differentiable" relating to lenses on google patents, although I tend to take those with a pinch of salt (e.g. http://www.google.ch/patents/CA1223142A?cl=en
https://www.google.com/patents/US5137343)
You can also see mathematical papers on lens design that refer to the (twice) "continuously differentiable" property e.g. https://arxiv.org/pdf/0704.1059.pdf

Also this question on lenses is essentially synonymous (except for the zweimal which yours doesn't mention) https://www.proz.com/kudoz/german_to_english/other/631537-zw...
