Abstract
The design of mirrors composed of multilayer stacks of dielectric films is considered. High reflectance over an extended spectral range is attained by positioning the stacks so that on a wavelength scale their high-reflectance bands are either contiguous or overlapping. Certain precautions must be taken in the choice of stacks to avoid deep-reflectance minima from developing within the extended high-reflectance region. Some of these are discussed and illustrated with both computional and experimental curves. The techniques of extending the high-reflectance regions are applicable not only to mirrors, but also to low- and high-pass cutoff filters and to multilayer polarizers.This publication has 3 references indexed in Scilit:
