Opsydia's secure laser marking technology is set to transform diamond security. Current industry-standard diamond identification is achieved by surface marking on the girdle of diamonds, the results of which are easy to polish off or replicate on inferior stones. View the video below to see how Opsydia technology can create tiny marks beneath the surface of diamonds, substantially improving their security without sacrificing clarity or grade.
Our secure laser marking technology can be used to create features inside transparent materials, including polymers, plastics, glass, gemstones (of many colours) and industrial diamond plates. The optical properties of these features can be carefully designed to give visually stunning effects in everyday lighting conditions. Security marks, serial numbers, holograms and other aesthetic features are all possible. The image below shows a holographic feature inside a plastic sample.
With exclusive intellectual property and technology developed in the University of Oxford, Opsydia's laser processes can be parallelised so that large areas of features can be created simultaneously, and with precise focal control to maintain feature quality at a range of depths.
Opsydia is in research & development stage of a number of advanced diamond-based sensors. The laser technology can be used to create very high spatial resolution electrically conductive tracks and electrodes within the bulk of industrial diamond plate.
Current research suggests that these techniques may be very promising for the manufacture of next-generation electrochemical, radiation and quantum sensing devices.
