Abstract
A simple null modulation-polarization method of measuring optical constants of metals has been adapted for operation with a KrF 248 nm excimer laser. The approach requires only 3 optical components to extract the real and imaginary parts of the index of refraction (n,k). Experimental results will show good agreement to reference values for several metals (Cr, Au, Al) and Si.
