Scientific paper

Some common metals and alloys have been identified as potential candidates with optical properties applicable to image plane masks for terrestrial planet finder (TPF) coronagraph especially for broad band performance in the visible spectrum. Thin films of these materials exhibit thickness dependence of refractive index and extinction coefficient which vary with wavelength and consequently the intensity and phase of transmitted light. We report on the fabrication and measurement of thickness-dependent optical properties of thin films of Ni, Pt and Inconel alloys to enable optimum design of image plane masks for Lyot coronagraphs to operate in the 500 to 800 nm band. We discuss the potential and limitations of practical masks with such materials.
