A product of Kepler's most creative period. It began as an attempt to give astronomical optics a solid foundation, but soon transcended this narrow goal to become a complete reconstruction of the theory of light, the physiology of vision, and the mathematics of refraction. It gives us insight into Kepler's thought during this crucial period.
First (and only) English translation of the work that founded the modern science of optics. Originally published in Latin in 1604. Many diagrams and footnotes.
