Optical filters play an important role in the areas of imaging, sensing, MEMS and photonics. This text gives an integrated presentation of this type of filter design that is rapidly becoming an integral part of these areas. Not only does the book give the reader a fresh look at the development of optical filter material; it is also dedicated to the explanation of omnidirectional optical filters. Beginning with the description of the basic optical phenomena behind these filters, the book moves on to classical filter design, and then newer designs. For the first time, omnidirectional short-pass, band pass, band-blocking and narrow band-pass filter designs are explained in detail. For graduate and undergraduate students interested in optics, photonics and MEMS, this book gives a thorough understanding of the design, fabrication and theory behind omnidirectional optical filters. Engineers in imaging, sensing and MEMS looking to learn more about these filters should also find it a valuable reference and tool.
