HNü 240

Built for Adaptive Optics' highest performance

The EMCCD camera
optimized for the highest AO performance

With frame rates up to 3000 fps in full-frame
The HNü 240 camera provides exactly what is to be expected from a high-end EMCCD Adaptive Optics (AO) optimized camera: virtually no noise with the high frame rates necessary to outpace atmospheric distortion. The HNü 240 also has the 240 x 240 pixels resolution critical to focal plane wavefront sensing and direct exoplanets imaging. Integrating the patented CCD Controller for Counting Photons, it creates fewer clock-induced charges than other EMCCD cameras. In short, it is the finest camera for your next great space discovery.

Outstanding SNR performances

  • Operation rate up to 3000 fps full frame
  • Pixel area of 24 μm x 24 μm
  • Readout rates 30MHz or 15MHz
  • Effective readout noise < 0.1 e- @ gain 5000

Adaptive Optics (AO) advantages

The goals of current and upcoming large telescopes require the highest level of AO performance. This, in turn, is driving demand for sensitive wavefront sensors that not only detect higher-order aberrations with a limited number of photons but also run at higher frame rates to outpace the changing atmosphere. To address these requirements, the HNü 240 camera delivers a full-detector frame rate of up to three thousand frames per second with sub-electron read noise and flexible readout sequences that can be tailored to different wavefront sensor designs.

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.
