Abstract: The present invention is an engraved gemstone viewer for viewing a flat, smooth surface of a gemstone that has been micro or nano etched with an inscription such as an identification number. The gemstone is mounted on a piece of jewelry or can remain unmounted when placed inside or otherwise received by the viewer.

The lens reflects the light beam along a path incident to the surface of the gemstone containing the inscription. The smooth flat gemstone surface spectrally reflects the light beam along a path back toward the magnifying lens, which produces a viewable light image that reveals the inscription. The inscription is shown as a dark or lightless region of the light image.

Abstract: A CO2 laser beam 12 is converted into a beam of uniform intensity at the position of a phase matching element 15 by an intensity converting element 14 and the phase matching element 15. Then, the uniform intensity beam irradiates a mask 17 containing an aperture variable in size via a variable-magnification projecting optical system 16. At the time of irradiation, the laser beam at the position of the phase matching element 15 is projected onto the mask 17 at a magnification factor most suited to the size of the aperture formed in the mask 17. Further, the pattern of the mask 17 is projected onto a workpiece 19. Thus, a uniform intensity distribution of the laser beam is obtained on the workpiece and high quality laser processing becomes possible.
