Leibniz-IPHT actively researches optically pumped magnetometers (OPM), a class of sensors with the best possible magnetic field resolution based on the current state of the art, only undercut by cryogenic superconducting detectors.

Such OPMs are extremely interesting for applications in (bio) medicine, in geosciences and z. B. also material testing. It is essential to read out the OPM measurement signals with as little noise as possible and with sufficient bandwidth. For the OPM test setups and functional models developed at Leibniz-IPHT, an extremely low-noise lock-in amplifier is required in order to be able to read the sensors at the technically feasible limit and to be able to demonstrate the corresponding sensor sensitivities.

- Scoring criteria: technical specifications 70%, price 30%.
