This book provides a unified treatment of the characteristics of telescopes of all types, both those whose performance is set by geometrical aberrations and the effect of the atmosphere, and those diffraction-limited telescopes designed for observations from above the atmosphere. The emphasis throughout is on basic principles, such as Fermat's principle, and their application to optical systems specifically designed to image distant celestial sources. The book also contains thorough discussions of the principles underlying all spectroscopic instrumentation, with special emphasis on grating instruments used with telescopes. An introduction to adaptive optics provides the needed background for further inquiry into this rapidly developing area.
Geometrical aberration theory based on Fermat's principle
Diffraction theory and transfer function approach to near-perfect telescopes
Thorough discussion of 2-mirror telescopes, including misalignments
Basic principles of spectrometry; grating and echelle instruments
