The utility model discloses a surface of water film thickness measuring device based on raman spectroscopy measures likens the peak height of water and oil hydro carbons pollutant raman signal into film thickness calculates the factor to, and at certain film thickness within range, film thickness calculates the factor and is linear relation with film thickness, through surveying calculation factor inverting water -out body surface oil film thickness. Measuring device is provided with light control circuit, the detection unit and signal processing transmission unit including three -dimensional adjustment module, three -dimensional adjustment support and can in the shell, the utility model discloses an advantage : can realize the direct measurement to water film thickness, detect fastly, avoid loaded down with trivial details step, not need chemical reagent simultaneously, not influence quality of water itself. Probe internal design has switch and lens, can effectively avoid the injury of the long -term output of laser to people's eye, the effective improvement arouses the raman signal.
