A method of determining surface plasmon resonances at a two-dimensional measurement surface as formed by a metallic film, the method comprising the steps of: bringing a specimen to be measured into contact with the measurement surface; illuminating the measurement surface with two collimated monochromatic laser beams of differing wavelength, which are spatially combined to form an overall beam; and measuring the difference in the intensities of the two laser beams of differing wavelength as reflected by the measurement surface, such as to characterise plasma resonance. |
