Spectrometer

摘要

The spectrometer contains an optical system (1) and a field stop (2) which is arranged downstream thereof and is designed such that it produces a spatial decomposition of the image of a section (6) of the earth's surface that is to be examined. Moreover, a dispersing device is provided which spectrally decomposes the radiation passing through the field stop (2) and generates an image of the spectrum on the photosensitive surface of a radiation detector (4) which converts the incident radiation into an electrical signal and whose dimensions are optically bound up with the dimension of the field stop (2). <IMAGE>
