Optical Waveguide spectroscopy
SIS5000/S-SPR60000 series
Optical waveguidespecrometry is very sensitive, since the incident light advances by repeated total reflection in the waveguide substract, and a sample on the waveguide surface absorbs the evanscent wave at every reflection point. The intensity of the evanescent wave diminishes strongly with distance from waveguide surface, and only distance similar to the wavelength of the incident light are effective in detecting the spectrum.This high-sensitivity is one of advantage for Interfacial analysis. |
