Paper Abstract

Diffractive optics is becoming a standard part of the optical designer's toolkit. The transition from design to manufacturing, especially for elements larger than a few millimeters in diameter, has been impeded by the relatively high cost of producing diffractive elements by standard photolithographic means. Replications techniques, such as injection molding, have the potential to significantly lower the cost for such elements. We report on results of the application of injection molding techniques to the replication of diffractive elements. Several examples of diffractives fabricated by these techniques, as well as present process capability, are discussed.
