A lens system for Thomson scattering plasma diagnosis is disclosed. The lens system for Thomson scattering plasma diagnosis comprises core area lens modules which are arranged to generate the scattered light when a laser penetrates plasma and to collect the scattered light of the center of the plasma; and edge area lens modules which are arranged to collect the scattered light of the edge of the plasma, wherein the core area lens modules include a first lens on which the light scattered sequentially from the center of the plasma is incident, a telecentric aperture arranged in the rear end of the first lens, second to fourth lenses arranged, in order, in the rear end of the telecentric aperture, a mirror arranged in the rear end of the fourth lens, and an upper surface having multiple optical fibers on which the light reflected by the mirror can be incident, and wherein the edge area lens modules include a first lens on which the light scattered sequentially from the edge of the plasma is incident, a telecentric aperture arranged in the rear end of the first lens, a mirror arranged in the rear end of the telecentric aperture, a second lens which is located in the proceeding direction of the light reflected by the mirror to face to the mirror and an upper surface having multiple optical fibers on which the light outputted from the second lens can be incident. |
