Latest Patents

One of Singer's latest patents is titled "Preparation of ultra-pure metal halides." This invention involves the ultrapurification of metal halides through selective complexation with a complexing agent. The process forms a charged first complex, while a ligand creates an oppositely charged second complex with metallic impurities. The resulting solution is passed through an ion exchange column, allowing for the collection of the desired purified metal halide. This method is particularly beneficial in producing ultrapure metal halides, such as zirconium fluorinate, which are essential for metallic glasses.

Another significant patent is "Multiple thin film absorption of reflected substrate modes in waveguide." This invention addresses the reduction of light reflections in substrate modes. By utilizing absorbing multilayer thin-film light interference coatings on the backside of a LiNbO.sub.3 substrate, the optical system effectively minimizes reflected substrate modes in integrated optical spectrum analyzers. This innovation operates at around 8300 A wavelength and can be adjusted for other selected wavelengths by varying individual film thickness and optical constants.
