Recent reports seem to confirm thet the firm Carl Zeins, Jena, and perhnpe
also the firn of Zeiss-Ikon in Dresden gontinee to build large mu-hers of
the Sonner lenses with a focal length of'5.8 cm. 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. The bransfokater lens wan later recalculeted in Dresden for visuel

The firn of Zeiss, Jena, is calculating a new microscopic condenser. 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. How Zeiss has arproached the DT{ for
money to start building such micro-interforometers aeain. Dirl. Ine. Bischof
la mentioned as being responsible for this renewed interest.
