Paper Abstract

We report designs of multilayer narrowband reflective 30.4 nm filters. The narrowband reflection filters are designed for angles of incidence (theta) o, ranging from 0 degree(s) - 30 degree(s). For example, the calculated reflectance of a 15-layer Au-Al multilayer which operates within the angular range 0 degree(s) <EQ (theta) o <EQ 10 degree(s) has for 0 degree(s) angle of incidence a reflectance peak value of 24% at 30.4 nm with a bandwidth of less than 5 nm. The average out-of-band reflectance is less than 2% for the wavelength range from 10 nm - 70 nm. Filters with more than 20% peak reflectance and less than 5 nm bandwidths are designed for incident angular cones from 0 degree(s) - 10 degree(s), 10 degree(s) - 20 degree(s).
