    an observation window which is positioned on said flat surface and has a surface as a light entrance surface being protruded a certain height from said flat surface;

    a fluid injection nozzle which is positioned on said flat surface and injects fluid toward said observation window;

    a first inclined plane which is disposed around at least a part of the periphery of said observation window facing said fluid injection nozzle and inclines such that whose height gradually decreases from the periphery of said observation window toward outside; and
