  • Lighting device
    Patent number: 9250197
    Abstract: A method of examining an object containing a polycrystalline material, in which at least one part of the surface of the object is illuminated with substantially isotropic light, as well as a illumination device for carrying out the method. In this manner, the polycrystalline material is less influenced by the different reflection characteristics of individual particles of the polycrystalline material.

  • Method and device for the detection of defects in an object
    Patent number: 8400630
    Abstract: A method for detecting defects in an object includes a step of locally illuminating the object by radiating in light having a wavelength to which the object is transparent. Multiply reflected components of the incident light are detected while the detection of directly transmitted components of the incident light is at least partly avoided and the detection of singly reflected components of the incident light is at least partly avoided. Defects are identified by evaluating intensity differences in the detected components of the incident light. There is also disclosed a device for carrying out the method.
