Abstract

PURPOSE:To remove harmful background spectral lines by providing a notch filter set for the harmful background spectral lines in front of the diffraction grating of the diffraction-grating spectroscope of the Thomson scattering light spectrophotometrical device of the plasma. CONSTITUTION:The light of a giant pulse ruby laser 1 is led to a plasma generating device 2, and the Thomson scattering light is led to the spectroscope 4 through a beam-condensing system 3. Then, it passes through an entrance slit 6, is turned into a parallel luminous flux by a collimator mirror 7, while the harmful background ruby-laser spectral lines are absorbed by the colored-glass filter 8 of the notch filter 9, and it is further separated into the spectral components thereof and condensed by a focus mirror 10. The light thus condensed passes a projecting port 12, is divided by a multichannel optical system 4' and detected by a photoelectric detector 5. By this constitution, the harmful background spectral lines are removed and thereby the precision of measurement can be increased.
