Abstract: We present a polarimetric method, based on the Jones matrix formalism, developed to investigate the first-order optical homogeneity of laboratory size specimens. After detailing the transfer function, layout, data handling and calibration, we discuss some commonly encountered practical cases. The results show that, at the current status, the method may provide maps of retardation and azimuth with uncertainties of some degrees and a spatial resolution of 50 mum(2) on 150 mm(2) framed fields. These uncertainties, which could be reduced with straightforward implementation, may be satisfactory for routine characterization of ordinary laboratory samples and may conveniently support growth technology and optical characterizations. The method may complement other established techniques aimed to assess sample perfection.
