Abstract:
1. A vision machine apparatus, comprising; an imaging sensor arranged to image an object, a radiation source arranged to generate radiation having a first property, and an object supporting base comprising (1) a radiation converter arranged to convert radiation having the first property into radiation having a second property, and (2) a member that is substantially transparent to radiation having the first property, is substantially transparent to radiation having the second property, comprises a glass member comprising two layers of glass and a light diffusing layer sandwiched between the two layers of glass, and has a lower surface to which the radiation converter is adjacent, wherein: the radiation source is arranged to project radiation having the first property through the member and onto the radiation converter, the radiation converter thereby producing radiation having the second property, the radiation converter is arranged to illuminate, with radiation having the second property, an object to be imaged by the imaging sensor that is separate from the vision machine apparatus, the object to be imaged is releasably locatable on an upper surface of the glass member arranged to support the object to be imaged, between the radiation converter and the imaging sensor, so as to be spaced from the radiation converter by the member, the object thus being back-lit by radiation having the second property produced by the radiation converter, and the radiation source is arranged to project radiation having the first property onto the object to be imaged and onto the radiation converter.
