In short

SPAD512² is a camera integrating a 512×512 SPAD image sensor. Up to 100,000 fps in 1-bit mode enable high-speed imaging (photon-counting). Fine time gating enables the study of time-varying samples.

Key benefits

Widefield camera

Widefield camera

Released in 2021, SPAD512² is the first commercially available SPAD camera in the world. The camera features a 512×512 SPAD image sensor for both photon-counting and photon-time gating applications. This camera is ideal to replace scientific CMOS and CCD cameras in widefield microscopy and high-speed imaging applications.

Wide detection spectra

Wide detection spectra and low noise

Our single-photon detectors are fabricated in a state-of-the-art CMOS process and offer an ultra-low dark count rate of less than 25 cps. Microlenses enhance the sensor's detection efficiency.

Timing resolution

Time gating

The sensor features time gating to study time varying signals of interest, such as FLIM. This makes it a perfect addition to any widefield FLIM microscopy setup.


Plug and Play

The system requires just a 5V power adapter and two USB3 cables to run. For full flexibility, 2 additional control lines can be connected to the SMA connectors. The industry standard C/CS-mount optical port and the M4 screw mounting positions offer a flexible integration into any existing optical setup.

SPAD512S integration

System integration

The detector is bundled with an intuitive software interface. The software gives easy access to all functionalities offered by our detectors, allows for fast prototyping and makes acquiring widefield single-photon data easier than ever. For the advanced users, we offer full remote control through a standard TCP/IP interface. This enables the user to take full control of the system from any TCP/IP capable software package, such as Matlab, Octave, Labview and Python.

SPAD512S widefield

Widefield video-rate imaging

Thanks to its large 512×512 SPAD image sensor, our camera is an ideal candidate to complement a widefield microscope. Time gating makes the camera a suitable candidate for widefield, video-rate FLIM applications. Other applications include high-speed imaging and quantum correlation imaging.
