<p>Abstract. We have developed an optical resonance system for observing the surface<br /> plasmon resonance (SPR). The SPR was successfully generated via a glass prism<br /> coupler in a Kretschmann configuration where the gold (Au) thin f1lm was<br /> thermally evaporated on the prism base. As a light source, a typical He-Ne laser<br /> with wavelength 632.8 nm was used to observe the SPR phenomenon. The angular<br /> scan in the attenuated total reflection (ATR)spectra shows the intensity drop (dip).<br /> That clearly indicates the SPR coupling phenomenon in the interface Au thin film.<br /> Some spectra of various Au thiclr..ness were also shown with identical angular<br /> positions of the dips.</p>
