Spectroscopic Instrumentation: Fundamentals and Guidelines for Astronomers

In order to analyze the light of cosmic objects, particularly at extremely great distances, spectroscopy is the workhorse of astronomy. In the era of very large telescopes, long-term investigations are mainly performed with small professional instruments. Today they can be done using self-designed spectrographs and highly efficient CCD cameras, without the need for large financial investments.

This book explains the basic principles of spectroscopy, including the fundamental optical constrai...
