HNü 512

Built for a balance between speed & field of view

The EMCCD camera optimized for performance

With industry-leading low-light SNR
Made for applications requiring the ultimate sensitivity in Space & Defense, Life Sciences, Physics, Industry and many other fields, the HNü 512 camera provides exactly what is to be expected from a high-end EMCCD camera: virtually no noise. This ultimate sensitivity enables highly efficient low-flux imaging, hence faster acquisitions and superior image quality.

Outstanding SNR performaces

  • Operation rate up to 90 fps full frame
  • < 0.001 e/pixel/frame background noise
  • EM gain up to 5000
  • Air-cooling down to -85°C

Highest quantum efficiency

The HNü 512 integrates the high QE (up to 95%) typical to high-end EMCCD detectors. Coupled with Nüvü’s patented electronics for the lowest background noise and the highest EM gain, this HNü 512 camera is ideal for applications requiring the utmost sensitivity in ultra-low light conditions.

Photon counting performance comparison

Thanks to Nüvü’s CCD Controller for Counting Photons, less clock-induced charges (CIC) are generated, the dominant source of noise in low light EMCCD imaging, providing at least 10x less noise than other cameras using the same detector whilst counting at least 15% more genuine photons.

Built for easy integration

The user-friendly HNü camera provides many advantages to efficiently bridge the gaps between purchase, setup and discoveries.

The HNü camera is a compact and easy-to-use device with a Windows or Linux operating system. To allow quick and easy integration into any system, all standard HNü cameras come with a C-mount optical interface, imperial and metric mechanical holes on the faceplate, and standard holding posts on the sides of the camera. For fast and reliable image data transmission, the HNü camera communication interface are either Gigabit Ethernet or Camera Link. A built-in shutter enhances detector longevity, allows dark frame acquisitions, and is remotely controllable with our software tools for all application requirements.

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.
