A research-grade goniospectrophotometer was modified to improve its measurement capabilities for appearance research. Hardware, optical, and environmental modifications produced a device capable of measuring the spectral reflectance factors of a sample over the wavelength range from 380 to 700 nanometers at user-selectable illuminating and viewing geometries. Several extensive Pascal programs were written to provide a user-friendly interface to facilitate the control of the instrument, as well as, the collection, reduction, and display of data.
