Abstract
This invention relates to the inspection of glass ampules to determine whether or not a complete score line is present. A laser beam is directed to the point on the ampule where a score line would be located. The laser beam is reflected in a diffuse or specular fashion depending upon whether or not a score line is present. By detecting the amount of light which is diffusely reflected in a particular direction, determination of the presence of a score line is possible. The same inspection may be utilized to determine whether the constriction on an ampule is of the proper diameter.
