<p><P>PROBLEM TO BE SOLVED: To provide a surface plasmon spectroscopic device high with spectroscopic precision. <P>SOLUTION: The surface plasmon spectroscopic device comprises two or more light sources, a prism, a specimen platform, and a photodetector, and uses two or more rays different in wavelength. The prism is a triangule pole prism, one of the rays is a near infrared ray while the other is a visible ray. The device is useful for in situ observation of chemical reactions and for observation of micro changes in the dielectric constant. The device is effectively employed for measuring the thickness of thin films such as a monomolecular layer or the dielectric constant. <P>COPYRIGHT: (C)2003,JPO</p> |
