I would recommend it for anyone studying optics, photonics or optical engineering. I wish I had this book when I started. It covers all the important areas of mathematics which are otherwise buried in many different maths courses, and links them to their application in optics through the "Focus" sections. Good for self study, additional exercises for a course and for checking your understanding. It would also be a good textbook for a course dealing specifically with the mathematics needed in optics, photonics and optical engineering.
