Abstract
1301537 Light-scattering by jewels Y TAKUBO and F SUZUKI 26 June 1970 31020/70 Headings G2A and G2J A device for observing the optical properties of materials such as jewels comprises an enclosure having means for supporting the specimen, which means has a source of electromagnetic radiation which is directed on to the specimen, and means for translating a rotary movement into a linear movement of either the support means or a lens forming part of an optical system within the enclosure. As shown, the specimen, which in this case is a jewel 1 mounted in a ring 2, is carried by a positioning head 31, and a miniature electric lamp 35 is mounted in a covering piece 34 at one end of the head, immediately behind the jewel. Piece 34 has a central hole 34a, through which the light passes to fall on the cullet side of the jewel. Above the jewel, in the wall of the enclosure 10, is a glass viewing panel for viewing the pattern of light scattered by the jewel. If a photographic film is placed in this position, a permanent record may be obtained. The head 31 is positioned at the end of an arm 30, and a screwed thread 32 passes through arm 30, one end being received in a recess 33. At the other end, external of the housing 10, is a knob 13, so that when this is turned, the whole of the arm 30, and hence the jewel, is raised or lowered, so that the image on the screen may be brought into focus. In the modification of Fig. 4 (not shown), the action of the knob 13 is transmitted to a lens system (40), which is moved axially to effect focusing.
