This paper describes the fundamentals of diffractive optics diffuser design, with an emphasis on common pitfalls and important design decisions. In addition, several new design and fabrication methods are presented, which overcome many of the current limitations of multi-level diffractive diffusers. These designs include an easily fabricated white-light diffuser and a uniform, high-NA diffuser design.
