Vacuum compatible cooling

Ultimate flexibility in cooling methods

Versatile imaging solutions for demanding conditions

Complete passive heat extraction for the thermoelectric cooling unit and electronics

Nüvü Camēras is once again at the forefront of innovation in CCD & EMCCD technologies, offering its signature performances in an imaging solution adapted to use in extremely rigorous or sensitive environments. From high altitude observation missions to state-of-the-art adaptive optics set-ups and more.

With standard cameras, you have access to air or liquid cooling options. Yet, even liquid cooling requires air flow; most notably to cool down the camera’s electronics. This causes these cameras to be unable to operate properly in low pressure conditions.

With passive heat extraction, the CCD & EMCCD is cooled entirely with liquid or by contact, enabling its usage in total and near vacuum conditions. Preventing air flow around the camera is also crucial for temperature or atmospheric-disruption sensitive environments.

This option is available on Nüvü’s camera controller and several of its proprietary camera models. From highest speeds to highest field of view, this heat dissipation flexibility opens up a variety of new applications that can benefit from the signature sensitivity and high performances of Nüvü’s technology.

CCCP

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.
