NV centers are individual atomic systems that act as highly sensitive sensors. Their unique advantage is their potential to be operated at room temperature and on background fields. They allow for extremely high spatial resolution and are being utilized in different imaging measurement methods.
The wide-field magnetometer was specially developed at Fraunhofer IAF and uses a diamond plate with a homogeneous layer of NV centers. It measures magnetic fields over a large sample area in a very short time, making it suitable for fast and quantitative measurements in industrial applications. The widefield magnetometer does not require calibration and can be used for the characterization and optimization of ferromagnetic materials as well as for applications in biomedicine.

High-resolution scanning probe magnetometers use diamond tips with a single NV center. This offers the unprecedented opportunity to measure and image magnetic field distributions at the atomic level, which were previously inaccessible with available methods. Example use cases include the representation of the current flows of micro- and nanoelectronic circuits in high resolution. Two scanning probe magnetometers from different manufacturers are available for measurements at the application laboratory.

In addition to the on-site testing facilities, a virtual version of the application laboratory for quantum sensor technology is available to industry and research: This information platform contains comprehensive specialist knowledge and offers the opportunity to independently explore the field of quantum sensor technology and assess solutions for specific application scenarios.
The virtual application laboratory includes three quantum magnetometers and offers detailed technical information and explanations of the different measuring principles of the systems. At the heart of the application laboratory are the interactive measurements, which illustrate measurement scenarios from the fields of materials testing, micro- and nanoelectronics and biomedicine.
Companies and institutions have the opportunity to assess the advantages and application potential of the devices for their specific needs. In addition, a website provides extensive information on quantum sensor technology and its potential applications. Professional contacts from the fields of research and technology transfer are available to share their expertise and provide advice.
