Thie is the bonb sighe lens used in the old "Stu ka Visier". The transfokator lens which Profess= Gremetzki calculated for the flu sans was originally based on the Sonnan lens.

IA the process it was found that all existing calculetions show strong spheric ii aberrations. e, Herr Linnik, a Russian, published something in Leningrad in 1937 on the nicro- interTaroretor. Zeiss took ur the idea in 1943 and built three such anparatuses. Dothing about them was published and no more were built because the Genan Army clamped down with security restrictions.
