The fourth edition of Pedrottis' Introduction to Optics is a comprehensive revision of a classic guide to the fascinating properties of light, now with new authors. Ideally suited for undergraduate optics courses in physics and electrical/electronic engineering departments, this edition adopts a distinctive phenomenological approach, bringing the underlying science to life through interactive simulations and beautifully revised figures. The modular structure and succinct style of previous editions has been maintained, while the content has been modernized, new topics have been added, and a greater consistency of terminology attained. For even more effective learning, a recurring theme of student engagement runs throughout the text, supported by a multifaceted pedagogical package that reinforces key concepts, develops a clear understanding of optical technologies and applications, and connects to students' experiences and observations from everyday life.

'I expect this edition to be as much a success as its predecessors. The book is a hallmark of clarity and especially accessible to students who may be encountering topics in optics and photonics for the first time. The inclusion of advanced topics highlights how the authors want the book to be a stepping stone into more specialised research topics, and the extensive problem sets - often with quantitative exercises based on real-world numbers - will make this very popular with instructors.' John M. Dudley, University Bourgogne Franche-Comté
'Exceptionally clear and readable! The diagrams are equally clear and well annotated, which contributes to pedagogical effectiveness. What I most appreciate is the breadth of coverage far greater than in any introductory optics textbook I have used.' Andrew Rex, University of Puget Sound
'I think this is a great book. Excellent detail of topics (for example Gaussian beam development is well done in my view).' Charles Nelson, United States Naval Academy
'Good selection of topics presented very well, easy for self-study.' Anna Petrova-Mayor, California State University Chico
'This textbook is extremely comprehensive, well illustrated, and notationally consistent between sections. I particularly like the integrated testlets and links to animations/simulations, which will greatly enhance the learning experience for students. The price point is competitive for such a large text.' Brynle Barrett, University of New Brunswick

Rayf Shiell passionately balances both research and teaching at Trent University, Canada. His primary research is in optics and ranges from probing matter using high-power laser beams to exploring the optics of the eye. He teaches a wide range of courses and delights in uncovering the often surprising connections between them. His love of good pedagogy has permeated not only this present text, from which he has taught for many years, but all his work as a mentor and instructor, extending also to coaching the university rowing team. He is co-developer of the integrated testlet, an assessment tool that employs a scaffolded answer-until-correct question structure, which features in each chapter of this text. For this work he was a co-recipient of Trent University's 2021 Award for Educational Leadership and Innovation. Iain McNab is a former Dean of the Faculty of Applied Science and Technology at Sheridan College, Canada; he counts among his mentors Nobel Laureates Harold Kroto and John Polanyi. At Newcastle University, UK, he was Head of the physics teaching laboratories and led research in laser spectroscopy. He has taught widely in physics and engineering and was an early adopter of innovative methods such as the flipped classroom and web-based learning systems. Iain is a former Chair: Spectroscopy Group of the Institute of Physics and currently runs the McNab Group, teaches for Canadian Laser Safety, and is a visiting Professor at Guangdong Technion Israel Institute of Technology, China. Matthew Romerein earned his M.Sc. in Materials Science from Trent University, researching polarimetry and spectroscopy. Working closely with the authors, he endeavoured to improve the clarity, scientific accuracy and educational impact of the figures in this book. The accompanying interactive animations were also designed by Matthew, who develops quality assurance testing software for the RF industry.
