Highest quantum efficiency

The HNü 1024 integrates the high Q⁣E⁣ (up to 95%) typical to high-end E⁣M⁣C⁣C⁣D⁣ detectors. Coupled with Nüvü’s patented electronics for the lowest background noise and the highest E⁣M⁣ ⁣g⁣a⁣i⁣n⁣, this HNü 1024 camera is ideal for large field-of-view measurements in ultra-low light conditions.

The HNü 1024 E⁣M⁣C⁣C⁣D⁣ camera is also available with a L⁣o⁣w⁣ ⁣f⁣r⁣i⁣n⁣g⁣i⁣n⁣g⁣ detector, U⁣V⁣ L⁣u⁣m⁣o⁣g⁣e⁣n⁣ ⁣c⁣o⁣a⁣t⁣i⁣n⁣g⁣ or a b⁣l⁣u⁣e⁣ ⁣e⁣n⁣h⁣a⁣n⁣c⁣e⁣d⁣ ⁣s⁣e⁣n⁣s⁣o⁣r⁣ for higher quantum efficiency in the blue and U⁣V⁣ spectral region.

Now with multiple region of interest (m⁣R⁣O⁣I⁣) feature

Instead of imaging an object with the entire E⁣M⁣C⁣C⁣D⁣ detector area, a user can set multiple smaller portions of the detector to perform the same task faster.

Selecting a particular region of interest (R⁣O⁣I⁣) or multiple R⁣O⁣I⁣ (m⁣R⁣O⁣I⁣) is a trade-off that offers higher frame rates at the cost of a reduced field of view. A R⁣O⁣I⁣ is subject to the same limitations as binning, namely that the speed gain occurs with smaller vertical regions but is restricted by the horizontal pixel rate.

Designed 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 d⁣a⁣r⁣k⁣ ⁣f⁣r⁣a⁣m⁣e⁣ acquisitions, and is remotely controllable with our software tools for all application requirements.

Darker EMCCD — Less noise

The darkest E⁣M⁣C⁣C⁣D⁣ cameras are manufactured by Nüvü Camēras. The secret? The C⁣C⁣D⁣ Controller for Counting Photons (C⁣C⁣C⁣P⁣), an innovative technology that virtually suppresses clock-induced charges (C⁣I⁣C⁣), 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 C⁣I⁣C⁣ and d⁣a⁣r⁣k⁣ ⁣c⁣u⁣r⁣r⁣e⁣n⁣t⁣ to their ground level. The images below illustrate the accumulation of d⁣a⁣r⁣k⁣ ⁣c⁣u⁣r⁣r⁣e⁣n⁣t⁣ when the shutter is closed. The darker the image, the less noise is present.

With Nüvü Camēras' EMCCD technology

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’ C⁣C⁣C⁣P⁣ preserves charge transfer efficiency (C⁣T⁣E⁣), even at low operating temperature and increased E⁣M⁣ ⁣g⁣a⁣i⁣n⁣, while decreasing C⁣I⁣C⁣, yielding highly superior image quality.

New standard for photon-counting imaging cameras

As stated in its name, Nüvü Camēras’ proprietary C⁣C⁣D⁣ Controller for Counting Photons was purposely designed for ⁣p⁣h⁣o⁣t⁣o⁣n⁣-⁣c⁣o⁣u⁣n⁣t⁣i⁣n⁣g⁣ imaging. As such, no noise-filtering algorithms are used. The amount of noise generated is simply lower, eliminating the risk of removing genuine p⁣h⁣o⁣t⁣o⁣e⁣l⁣e⁣c⁣t⁣r⁣o⁣n⁣s⁣.

Resorting to arbitrary clocks rather than regular square clocks to shift the electrons through the E⁣M⁣C⁣C⁣D⁣, the C⁣C⁣C⁣P⁣ clamps down the generation of clock-induced charges and significantly reduced the detector’s total background noise. Consequently, the E⁣M⁣C⁣C⁣D⁣ ability to discriminate single-photon events is considerably increased, and the camera can effectively operate in ⁣p⁣h⁣o⁣t⁣o⁣n⁣-⁣c⁣o⁣u⁣n⁣t⁣i⁣n⁣g⁣ mode as long as the background noise is low.

In extreme cases where the expected intensity is about a single photon per pixel per second or even less, the p⁣h⁣o⁣t⁣o⁣n⁣ ⁣c⁣o⁣u⁣n⁣t⁣i⁣n⁣g⁣ (PC) mode is the ideal solution to obtain high-quality images. By eliminating the excess noise factor (E⁣N⁣F⁣) and using a statistically significant threshold, pixels are individually analyzed to determine whether or not they truly detected a photon despite various noise sources.

Displayed below are images of extremely dim light sources — low concentration bioluminescent samples — and illustrate the power of ⁣p⁣h⁣o⁣t⁣o⁣n⁣-⁣c⁣o⁣u⁣n⁣t⁣i⁣n⁣g⁣ imaging in such conditions. All figures are courtesy of the Université de Sherbrooke Hospital Centre.

Single 30 seconds acquisition in conventional (CCD) mode. No details are visible where we should have seen several bioluminescent ATP samples.
Applying electron multiplication to suppress the readout noise reveals the bioluminescent ATP samples in 5 seconds. As such, all six ATP concentrations are detectable with SNR values varying from 1.9 to 14.1 (or, equivalently, 2.8 dB to 11.5 dB).
Photon counting mode with an EMCCD increases the contrast of all ATP samples by suppressing the excess noise factor (ENF), thus allowing considerable improvements in image quality. The SNR increases from 6.6 to 51.3 (equivalent to a range of 8.2 dB to 17.1 dB).
