The history of astronomy and astrophysics goes along with the development of ever more powerful telescopes and instruments. Spectroscopy has proven itself to be one of the most important methods. In the course of time, researchers were able to filter increasingly more detailed physical information from the light of stars with spectroscopy.
The talk will begin with a historical overview of spectroscopic instruments and methods. Carsten Denker will especially introduce the historical facilities on the Telegrafenberg in Potsdam, the Great Refractor and the Einstein Tower, and typical instruments such as prism and grating spectrographs. Furthermore, he describes how these basic instrument concepts inspired a new generation of spectrographs in operation at the German solar telescopes on Tenerife or on space missions. Besides spectroscopic studies in the visible range, other wavelength ranges will be explored as well, covering the electromagnetic spectrum from extreme ultraviolet to infrared.
We look forward to your visit!
