Diamonds with NV (Nitrogen – Vacancy) centres are the core technology of our company. This atomic defect in the crystal structure of diamonds gives them special optical and quantum properties, which we exploit in our developments.
To know the quantum quality of the diamonds we use, we have developed a test bench, based on a confocal microscope with a laser at 520 nm. To characterise your diamonds, we put at your disposal, this characterisation tool, as well as our skills.
We offer a fast response and a detailed analysis, with a dedicated measurement bench.
You can choose what kind of tests you want, among the proposed analyses, or directly get in touch with us to define the test program.
