Astronomical spectrographs analyse light emitted by the Sun, stars, galaxies and other objects in the Universe, and have been used in astronomy since the early nineteenth century. This book provides a comprehensive account of spectrographs from an historical perspective, from their theory and development over the last two hundred years, to the recent advances of the early twenty-first century. The author combines the theoretical principles behind astronomical spectrograph design with their historical development.
Spectrographs of all types are considered, with prism, grating or prism dispersing elements. Included are Cassegrain, coude, prime focus, echelle, fibre-fed, ultraviolet, nebular, objective prism, multi-object instruments and those which are ground-based, on rockets and balloons or in space. The book contains several tables listing the most significant instruments, around 900 references, and over 150 images, making it an indispensable reference for professional astronomers, graduate students, advanced amateur astronomers, and historians of science.
'Astronomical Spectrographs [and their History] is a concise and comprehensive synthesis of the development of the designs and uses of astronomical spectrographs and provides a most valuable resource for any study in this field. It is to be hoped that the work will encourage as much fruitful work in the history of astronomy and astrophysics as did Hearnshaw's earlier books.' Journal of the History of Astronomy
