Description
der Bildebene 14 haben, zur Modulationsscheibe, welche in derselben Ebene angeordnet ist.of the image plane 14 have to the modulation disk, which is arranged in the same plane.
Das danach divergente Büschel mit der Apertur «2 = Oi1 durchdringt die erste Lins2 des Aperturtransformators 5, wonach es als paralleles Bündel über den Strahlenteiler 6 in die zweite Aperturtransformatorenlinse 7 bzw. 8 mit der Apertur a3 gelangt. Hiernach, als wiederum konvergierendes Büschel, das durch die Autokollimationsspiegel 11 bzw. 12, die ihre Brennpunkt? auf der jeweiligen Zelle haben, korrigiert wird, gelangt die aufgenommene ungestörte Strahlung auf die gekühlten Zellen.The then divergent tuft with the aperture 2 = Oi 1 penetrates the first lens 2 of the aperture transformer 5, after which it arrives as a parallel bundle via the beam splitter 6 in the second aperture transformer lens 7 or 8 with the aperture a 3 . Thereafter, as a converging tuft that is again converging through the autocollimation mirrors 11 and 12, which are their focal point? on the respective cell is corrected, the recorded undisturbed radiation reaches the cooled cells.
Um nun außerdem zu verhindern, daß durch dieIn order to prevent the
Modulationsscheibe 4, welche in der Bildebene liegt, Störstrahlung auf die ZeUe gelangt, muß diese wieModulation disk 4, which lies in the image plane, Interfering radiation reaches the cell, this must be how
oben erläutert ausgeführt sein. Außerdem muß hinter dem Strahlenteiler, hinter der Fläche desselben, welche gegenüber der Zelle 10 liegt, ein hochreflektierender Planspiegel 13 gut justierbar, wie vorab beschrieben,be executed as explained above. In addition, behind the beam splitter, behind its surface, which opposite the cell 10, a highly reflective plane mirror 13 is easily adjustable, as described above,
