Built for unmatched electron transfer

The CCD controller for counting photons

CCD & EMCCD new standard in low light imaging
Nüvü’s first strength is in the development of electronic controllers unlocking the full capacities of high-end CCD & EMCCD detectors for maximal performances in demanding low light applications both on earth and in space.



The CCCP, Nüvü’s proprietary controller included in all its imaging products, uses an innovative clocking architecture and allows driving the CCD and the EMCCD in a unique way. CCCP’s design is optimized for the driving of EMCCDs as fast as 30MHz of pixel rate or for slow readouts to optimize low readout noise. Using this CCCP controller, the dominant photon counting source of noise with EMCCD cameras, the Clock Induced Charges (CIC), were reduced down to < 0.001 electron/pixel/frame (depending on the detector). Therefore, with the lowest background noise, Nüvü is the sole EMCCD camera manufacturer that offers cameras supporting EM gain up to 5000 for optimal photon counting performances.

Furthermore, with the vertical CIC down to negligible levels, the CCCP enables using the camera entirely in the Inverted Mode of Operation (IMO) for the reduced dark current resulting in lower total background signal, even when using long exposure times. The CCCP enables the readout of up to four outputs, but is also compatible with controller multiplexing, where up to four controllers can be synchronized for reading a maximum of 16 outputs.

Outstanding performances

  • Up to 30MHz pixel readout
  • Lower CIC with higher EM Gain
  • Full control over readout sequences
  • Up to 4 outputs
  • Higher charge transfer efficiency
  • Fully programmable FPGA (VHDL)

For experienced users

The CCCP line of CCD and EMCCD controllers is available for experienced ultra low-light camera builders. To benefit from the CCCP controller’s performance, one must consider all potential noise sources across the entire setup while building a customized camera.

The CCCP allows complete control over the CCD clocks used for detector readout, enabling optimization  to a specific detector. This control over multi-level clocks is key to achieving minimal noise. Integrated saving and loading features allowing to quickly working with several personalized readout sequences for enhanced flexibility. Moreover, programming the clock signals is done through a user-friendly interface, making it simple to implement adjustments to your setup.

Darker EMCCD — Less noise

The darkest EMCCD cameras are manufactured by Nüvü Camēras. The secret? The CCD Controller for Counting Photons (CCCP), an innovative technology that virtually suppresses clock-induced charges (CIC), and a cooling Peltier unit integrated into an ingenious packaging. The thermoelectrically cooled HNü camera operates between -60 and -90°C with outstanding precision to optimize CIC and dark current to their ground level. The images below illustrate the accumulation of dark current when the shutter is closed. The darker the image, the less noise is present.

No pixel leaking, superior image quality

At high readout speeds, the electron transfer from one potential well to the next may be incomplete, leaving a few charges behind. Consequently, the leftover electrons artificially increase the brightness of certain pixels, thereby diminishing the overall image quality with the addition of arbitrary blurry spots. However, Nüvü Camēras’ CCCP preserves charge transfer efficiency (CTE), even at low operating temperature and increased EM gain, while decreasing CIC, yielding highly superior image quality.
