A contemporary approach to optics with practical applications and new focused pedagogy, Hecht Optics balances theory and instrumentation to provide you with the necessary classical background through a lively and clear narrative. Optics fifth edition is distinguished by three core imperatives for the reader: up-to-date content in line with the ever-evolving technological advances in the optics field; a modern approach to discourse including studies on photons, phasors, and theory; and improvements and revisions to the previous edition's pedagogy including over one hundred new worked examples.
