Achromaticierimg the lenses an act of great importance had te, aas w-round the two bustards voa. Lentils one negative and one positive - ■ from several double cylinders exist., of which; each one half aas flint - and half of the EroBglas consist.

but it is taken into account that one and the same optical © system aar recording mad KUr projection can be used, by putting exactly the same focal-less apparatus first in front of that Aufnahaeobjektiv sets and then later in front of the lens of the projection apparatus, they will all be with the consuming one Incorporating errors largely corrected afterwards » not only the image distortion * but aaoh chromatic defects.

On the basis of this observation, an invention was made created the new system that only has two lenses * one Tsar scattering and one collecting j the scattering one made of stained glass and the collecting aas crown glass, with a refractive index of 1 * 523 and a dispersion of JCronglaees of 61.9 *

With a ratio of the power of these two lenses of plus 5 to minus 1.0 diopters, an amauaorphization is achieved for the panorama sun umbrellas, which have become sofeon lifelioh today, with one SaltenTerhaltnii of 1: 2.55 (Cinemascope). Of these two single muse, each has at least one side with a cylindrical

while the other side is flaoh either _? may be spherical cylindrical Ameh * The N ^ \ xe system is therefore of only two niöht ausammengesetaten lenses, one of which minus IQ Imoe. the other one has plus 5 diopters, and the lenses can be flat £ 5ylindrisök or foi-aylin & rlseh.

This new optisöh © afocal anamorpkisierende system is tested in practice with ä®n best .Resultaten and has the befindliolien in Landel systems over significant Torzftge particular it zeiehnet look at good efficiency dureJi
