Built for long exposure times

The liquid nitrogen-cooled EMCCD & CCD camera

With the highest signal-to-noise ratio for photon-counting imaging applications
Thanks to cooling down to -110°C, the EM N2 camera line generates the least amount of dark current. Combined with Nüvü’s patented CCCP technology to significantly reduce clock-induced charges, this EMCCD camera provides unmatched sensitivity for long exposures. The highly personalized EM N2 camera supports 3 standard EMCCD detector sizes (128, 512 and 1024) in addition to custom sizes CCD and EMCCD detectors for specific requirements.

What cooling temperature?

The EM N2 liquid nitrogen cooling system offers flexible means to optimize sensors’ performances: the ability to cool all the way down to -110 °C allows users to attain their desired balance between dark current and charge transfer efficiency (CTE). The very best image quality can be attained via adjustable cooling temperature with any high sensitivity sensor — even those of non-standard or custom size ratios.

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.
