A new approach for the measurement of a refractive index is presented, following the introduction of a novel feature based on the selection of a large number of angles of incidence along a direction of symmetry at the prism-ambient interface, without moving the incident beam. This gives rise to very high sensitivities over a refractive index range determined by the divergence of this beam. © 2005 Society of Photo-Optical Instrumentation Engineers.
