Lighting device |
| 摘要 |
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. |

1. An illumination device for examining an object having a polycrystalline material, the illumination device comprising:
a hollow body having an inner surface with a light reflecting layer, said hollow body formed of a tube and two spherical caps connected to each other by said tube, thereby providing an inwardly oriented reflecting surface formed from said inner surface and said light reflecting layer following a contour of said tube and said spherical caps; and illuminants disposed in said hollow body to illuminate a surface of the object having the polycrystalline material with substantially isotropic light. |
