Uniform response across the field of view
A spatially consistent NV population helps maintain comparable fluorescence and magnetic response across the image area.
Wide-field NV imaging uses an ensemble of NV centers distributed across the sensing area. Under optical excitation, the spatially varying spin response is read out in parallel and converted into a two-dimensional magnetic-field map.

Parallel readout across the full optical field of view.
Translate spatial spin response into magnetic-field information.
The magnetic sample can be measured without electrical contact to the sensor.
Wide-field imaging is fundamentally different from single-NV point sensing: many NV centers contribute simultaneously, so uniformity across the sensing plane and sample proximity become central material requirements.
A spatially consistent NV population helps maintain comparable fluorescence and magnetic response across the image area.
Bulk ensemble material or an engineered NV-active layer can be selected depending on sensitivity, spatial resolution and distance to the sample.
Surface quality, polishing, crystal orientation and sample geometry can be matched to the optical setup and device architecture.
Nova can provide bulk NV-ensemble material, engineered NV-active layers and {111}-oriented ensemble platforms depending on the required signal level, depth, orientation and dimensions.
Uniform NV-ensemble material for high-sensitivity magnetometry and wide-field magnetic imaging. NV concentration can be selected around the experiment.

Discuss layer design →{111}-oriented ensemble material is available when surface-normal NV alignment simplifies the external magnetic-field or optical geometry.
