An apparatus for determining the shape of a gemstone, including irregularities on its surface, is provided, The apparatus comprises a platform adapted to support the gemstone, a scanning system adapted to provide geometrical information concerning the three-dimensional convex envelope of the gemstone, an illumination system adapted to project on the gemstone a plurality of laser beams, an imaging system adapted to capture reflections of at least a part of said laser beams from the surface of the gemstone, and a processor. The processor is adapted to calculate, based on said geometrical information, a predicted reflection of each laser beam, to compare the captured reflections with said predicted reflections and to relate each captured reflection to its corresponding predicted reflection, to determine said shape of the gemstone based on the comparison and said geometrical information.

Apparatus for determining the shape of a gemstone

A method for accurately mounting an optical element in an optical assembly including precisely positioning the optical element in a desired position with respect to a reference surface and spaced from the reference surface and employing an adhesive for fixing the optical element in the desired position including employing at least one side mounting element separate from the reference surface including at least one first surface which engages an edge of the optical element and at least one second surface which engages the reference surface.

Method for accurately mounting an optical element in an optical assembly

An optical device in which a waveguide is mounted on an optical substrate in turn supported on a base substrate. The base substrate is provided with an optical fiber positioning groove into which an optical fiber is fixed so that a center of the fiber lies in a plane substantially coplanar with a plane of the waveguide.

Method for producing an optical device and the optical device produced thereby

An optical device having a multiplicity of optical fibers fixed in respective grooves in a first substrate in a predetermined arrangement in an optical fiber plane. A second substrate is fixed onto the first substrate such that an edge of the second substrate extends beyond the ends of the optical fibers. A lens assembly including a third substrate, and a lens fixed on the third substrate is mounted on the second substrate such that the lens lies in a second predetermined arrangement with respect to the ends of the optical fibers and is spaced from them in a plane perpendicular to the optical fiber plane with a first degree of accuracy and in the optical fiber plane with a lesser second degree of accuracy.
