The method comprises directing light, in the visible light spectrum, of from approximately 4900 to 5800 Angstrom units onto workpieces, or onto containers having translucent bodies in order to illuminate the workpieces, or both the containers and fluent material contents of the containers, the method having a particular utility in inspecting workpieces in assembly or quality control operations, and in inspecting vials, ampoules, and the like, to evaluate and/or detect structural fissures, disconnections, fractures, etc. in such workpieces, and growths (i.e., egg embryos), foreign matter, and the like, in the fluent material contents of the containers, as well as the condition of the containers themselves. The apparatus comprises means suitable for practicing the novel method, and includes a support for the workpiece or fluent-material-confining container, a television system for viewing and displaying the illuminated workpiece or container and contents, and a light source which provides radiation substantially in a range of from 4900 to 5800 Angstrom units, for effecting the desired illumination of the container and contents, or workpiece, at not more than approximately 0.05 foot-candle.

An improved apparatus for inspecting translucent-body containers, and fluent materials contained within such containers, having means for disposing a translucent-body container having fluent material therewithin in an attitude for illumination thereof from an external light source, having a source of light, and further having means for directing light from said source onto a fluent-material-containing, translucent-body container disposed therefor by said container disposing means, to cause illumination of both said container and fluent material therewithin, wherein the improvement comprises: said light source comprises means restricting illumination of a fluent-material-containing, translucent-body container to only approximately 0.05 foot-candle, to minimize undue surface reflection and light scattering, and further comprises means providing illuminative radiation in which a substantial portion thereof is within a range of approximately from 4900 to 5800 Angstrom units.
