Abstract: A system and method of visually inspecting a transparent body and a translucent body comprises applying light to a reverse surface of an object to be inspected by a transmission light source, and applying light, at a low angle, to at least one of an obverse surface and the reverse surface of the object to be inspected by a reflection light source. Concave defects and adherents of the object to be inspected are detected by use of transmitted light emitted from the transmission light source, and adherents of the object to be inspected are detected by use of reflected scattered light emitted from the reflection light source.

Abstract: An method and device for inspecting for surface defects, internal defects, and surface-adhered foreign matter on semitransparent materials. An illuminating device transmits light, that is then collimated through a collimating lens unit, through an object to be inspected. The light then transmits through the object to be inspected an eventually is detected by a detector. Any defects in the object to be inspected will be detected.
