Abstract
Gradient index coatings, or rugate filters, may be of interest to more easily achieve optical properties such as `notch' filters that are difficult to reach with classical multilayers. Rugate coatings have been fabricated using a new evaporation system. This system uses two coupled masking devices to control the rate of two sources kept at constant temperatures. Two couples of materials were studied and sine wave index profile rugate filters were fabricated.
