Laboratory, optical and precision equipments (excl. glasses)

Tender description

The National Physical Laboratory require a Nitrogen-vacancy scanning probe microscope: scanning probe system based on the optical read out of the quantum state of a NV defect implanted in diamond probe. The quantum state is perturbed by magnetic field, hence, allows for high sensitivity magnetic field measurements that are spatially resolved at the nanometre level. The National Physical Laboratory (NPL) require a Nitrogen Vacancy (NV) scanning probe microscope (SPM) system operating on quantum principles and with the ability to spatially resolve micro-Tesla magnetic fields with nanometre precision. The equipment has to include a scanning stage system with capabilities comparable to commercial AFM systems (i.e. scanning range, noise/drift performance). The system will also be able to perform a range of NV imaging modes: quenched mode scanning, quantitative field scanning and as such will include all the necessary optics, laser sources and microwave electronics to be able to do so.
