Claims

[Scope of claim for utility model registration] (1) Light emitted from a projector is irradiated onto the object to be inspected, the scattered light from the object to be inspected is received by a receiver, and a line sensor therein conducts photoelectric conversion to determine flaws. This is an optical device for a flaw inspection device, the light projector including a plurality of halogen light source sections, a plurality of optical fiber bundles that receive light from the halogen light source sections, and an array of the optical fiber bundles having a slit shape in cross section. a fiber exit end face that converts the light into a slit light, and a condensing section that collects the light emitted from the fiber exit end face and converts it into slit light; What is claimed is: 1. An optical device for inspecting flaws, comprising: a light condensing section directed toward the surface; and a line sensor that photoelectrically converts scattered light collected by the condensing section. (2) A flaw inspection device according to claim (1), characterized in that a neutral density filter is attached to a portion of the fiber exit end face where the output light is strong, so that the intensity of the output light from the fiber exit end face is made substantially uniform. optical equipment. (3) the optical device for flaw inspection according to claim (1);
1. A flaw inspection device comprising a cleaning means provided near the surface of an object to be inspected.
