4K EMCCD solutions

Built for the widest field of view

The largest EMCCD detector, supported by Nüvü Camēras

With 16 MP EMCCD powered by Nüvü’s signature electronics
This new detector, called CCD282 by manufacturer Teledyne-e2v, is the EMCCD’s missing link to compete against other large format imaging technologies like CMOS and CCD. Nüvü Camēras is the first company to efficiently support the Teledyne-e2v CCD282 (further called 4K EMCCD) with CCCP 4K. A first complete imaging solution with the 4k EMCCD has been developed for the Canadian Space Agency and more are on its way.

The 4K EMCCD is a unique high-resolution, low-noise EMCCD detector; perfect for applications with wide fields of view or high-resolution spectroscopy. The new EMCCD sensor features 4096 pixels x 4096 pixels, with 12 μm square pixel area, in a split-frame transfer architecture. The die size of the largest EMCCD detector is 104 mm x 51 mm with a total package size of 125 mm x 70 mm.

CCCP 4K

Thanks to Nüvü’s proprietary electronic controller, the CCCP 4K, the detector’s 8 outputs are supported through readout electronics and the dominant source of noise of EMCCDs at low flux level and high frame rate, the Clock Induced Charges (CIC), are reduced at the minimum level and allow for efficient photon counting. The CCCP 4K enables full control of 8-output CCD or EMCCD detectors clocks and flexible readout sequences, which is crucial to reach minimal noise. This technology is also available with space-qualified components (See CCCPs). Nüvü Camēras is currently the only EMCCD manufacturer supporting the largest format EMCCD detector at 8 outputs.

 

4K EMCCD solutions

The 4k EMCCD detector is significantly more sensitive and a better alternative to the more commonly used CCD231-84 16 megapixel detector. Indeed, EMCCD technology allows for better low-light imaging performances compared to a standard CCD and has photon-counting capabilities.

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.

Acquisition conditions: -85 °C cooling, 10MHz readout speed, EM gain of 5000 for Nüvü Camēras, and 1000 for other EMCCD manufacturers.

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.
