Paper Abstract

In this paper the design of two different graded reflectivity mirrors is described. Using the thickness variation of the middle layer of a symmetrical (H L)2 H stack, a superGaussian reflectance profile was obtained. The dependence of the superGaussian parameters on the deposition geometry was investigated and the results are discussed by comparison with an other graded reflectivity mirror, for which the thickness of the overall high reflecting coating presents a radial variation. The design of a graded reflectivity mirror with a parabolic reflectance profile is also given. The dependence of the parabola parameter on the deposition geometry was calculated for the same deposition conditions.
