This comprehensive reference presents an introduction and review of the optics and methods of microoptic elements with particular emphasis on lenses and lens arrays. The second edition of Microoptics Technology includes information that has emerged in the five years since the first edition. With two new chapters and another fully expanded, the book deals with all of the current and new methods of fabrication of microlenses as well as refractive, GRIN, and diffractive methods. It also includes chapters on optical devices that utilize the microoptic fabrication methods, including micro-diffraction gratings and optical isolators, along with discussions of a number of important applications.
