The Physics of Thin Film Optical Spectra

This book connects fundamental physics concepts with advanced topics in optical thin film coatings, presuming a basic understanding of optics, electrodynamics, quantum mechanics, and solid state physics. It provides a comprehensive theory of optical coatings, employing both classical and semiclassical methods. Readers will find practical applications in spectroscopy, with examples covering classical optical coatings and innovative subjects like rugate filters. The updated second edition includes new insights on spectral probing, line broadening mechanisms, and the Fresnel formula for planar interfaces.
