NV Ensemble
Diamond
Uniform, controllable NV-center populations engineered for high-sensitivity quantum sensing, wide-field imaging, prototype sensors and device integration.
More spins give more signal.
The material still has to stay controlled.
Ensemble sensing is a materials-engineering problem: NV density, nitrogen background, isotope composition, strain and surface preparation all influence the final sensor response.
Choose the NV concentration around the measurement.
Lower-density ensemble material can favor spin performance, while higher-density material increases ensemble signal. Nova can tailor the concentration to the sensing architecture rather than forcing one material grade onto every experiment.
Standard ensemble configurations span low-density through high-signal regimes.
Higher-density and project-specific concentrations can be discussed for device programs.
Choose a uniform bulk ensemble or an engineered active layer depending on sensing volume.
Lateral dimensions up to 10 mm and thickness up to 3 mm can be provided for maser, resonator and device integration.
Built for ensemble quantum
sensing and device development.
NV ensemble diamond is most useful when the material parameters are selected together with optical collection, microwave delivery, magnetic-field geometry and the intended sensing volume.
High-Sensitivity Magnetometry
Large numbers of NV centers provide collective optical signal for magnetic-field detection.
Wide-Field Imaging
Uniform ensembles enable spatially resolved magnetic, thermal and stress measurements over an optical field of view.
Maser & Device Integration
Large crystal size, custom thickness, side-wall angle, chamfering and polished side faces can be engineered around microwave resonators, optical paths and package geometry.
Configure the ensemble.
Standard product grades cover the most common ensemble-sensing regimes. For specialized sensors, NV concentration, isotope composition, active-layer thickness, lateral size, thickness, edge geometry and surface finish can be customized.
Not every ensemble experiment
fits a standard plate.
For microwave masers, resonators and integrated sensing hardware, crystal geometry can matter as much as NV concentration. Nova can process the diamond around the optical, microwave and mechanical boundary conditions of the device.
Control the faces that interact with the field.
Large and thick NV ensemble crystals can be prepared with custom side-wall angles, chamfers and polished side faces to support microwave mode engineering, optical access and mechanical integration.
Useful where pump, fluorescence collection or cavity coupling uses a side surface rather than the top face.
Side-face angle can be processed around resonator geometry, optical path or mechanical mounting requirements.
Chamfers and bevels can reduce edge fragility and adapt the crystal to fixtures, cavities and holders.
High-density NV material can be combined with larger custom geometry for microwave cavity and spin-ensemble experiments.
One ensemble platform.
Several sensing architectures.
Use NV ensemble diamond where the experiment benefits from collective signal, spatial imaging or integration into a sensing prototype.
Quantum Magnetometry
High-sensitivity magnetic-field sensing using ensemble fluorescence and spin resonance.
Wide-Field Imaging
Magnetic, thermal and stress imaging over a microscope field of view.
Bio-Magnetic Sensing
Ensemble platforms for weak magnetic signals and spatially resolved biological measurements.
Quantum Microwave Maser
High-density NV ensembles with custom size, thickness and side geometry for microwave cavities and spin-ensemble systems.
Design the material around
the sensor architecture.
Nova can tune the ensemble together with crystal geometry, isotope composition and downstream processing.
