Abstract: PURPOSE:To make it possible to perform the visual inspection of materials to be inspected having different reflectivities by providing a light-quantity adjusting mechanism which controls the quantity of light variably on the light path for illumination light, reflected light or scattering light. CONSTITUTION:Illumination light 4 which is emitted from a condenser lens 8 in an illumination optical system A is reflected with a semi-transparent mirror 10. The light is projected on a material to be inspected 2 which is mounted on an X-Y table 1 through an objective lens 9. The light, among reflected light and scattering light 4a from the material to be inspected, which is captured with the lens 9 is guided to an image sensor 12 through the semi-transparent mirror 10 and a semi-transparent prism 11. The sensor 12 detects the image signal at the specified part of the material to be inspected 2 in one dimension. The table 1 is driven, and the material to be inspected 2 is relatively moved with respect to an image sensing optical system B. The presence or absence of defect on the surface pattern of the material to be inspected 2 is detected. A control part 19 drives a light-quantity reducing filter 18 through a driving mechanism 17 based on data 20 regarding the material to be inspected 2, and the quantity of the light is adjusted.
