  • Light scanning device for determining the condition of a surface with a light concentrator
    Patent number: 4693601
    Abstract: A light scanning device for determining the condition of a surface has an optical system which concentrates light beams leaving a scanning line in a specific direction at a concentration zone (16'). A light concentrator (11) with a light entry surface (12) and a desired light exit surface (13) arranged parallel thereto are arranged at the location of the concentration zone (16'). Convexly curved side surfaces (15) which are mirrored at the outside are present between the light entry surface (12) and the desired light exit surface (13) and ensure that light entering alongside a dark field stop (14) all falls onto a photomultiplier which adjoins the desired light exit surface (13) (FIG. 5).
