Hecht's "Optics" is my first go-to (https://www.amazon.com/Optics-5th-Eugene-Hecht/dp/0133977226). There are a few other classics textbooks, like Born amd Wolf's "Principles of Optics" too.
I find Hecht has a great balance of theory and practice, with good figures and comprehensible treatment of the subject (for a non-specialist experimental solid mechanician).

Complement this with Schaum's Outline of Optics (also by Hecht) to practice lots of exercises.
MIT Open Courseware has a series of video clases on the topic:
