By Nuvu Cameras
Nüvü Camēras uniquely offers 30 MHz pixel readout rates on all its models for unmatched imaging speeds and supports multi-output sensors, such as with the HNü 240, which enable faster frames rates even with larger sensors.
The CCCP controller line offers a flexible and customizable readout architecture for a variety of CCD & EMCCD sensors. Offered for both space-based and ground based use. The CCCP is the technology behind Nüvü Camēras’ high-performance sensitivity in low light imaging. Thanks to unmatched control over the charge transfer process, the CCCP generates significantly less CIC than any other CCD and EMCCD controller. - CCCP – controller Built for unmatched electron transfer - CCCPs – controller Built for unmatched electron transfer in space-based conditions

Features for faster acquisition - Crop Mode - Fast Kinetics Mode - Time-Delay Integration (TDI) Mode - Multiple Region of Interest (mROI) & ROI 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.

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. New standard for photon-counting imaging cameras As stated in its name, Nüvü Camēras’ proprietary CCD Controller for Counting Photons was purposely designed for photon-counting imaging. As such, no noise-filtering algorithms are used. The amount of noise generated is simply lower, eliminating the risk of removing genuine photoelectrons. Resorting to arbitrary clocks rather than regular square clocks to shift the electrons through the EMCCD, the CCCP clamps down the generation of clock-induced charges and significantly reduced the detector’s total background noise. Consequently, the EMCCD ability to discriminate single-photon events is considerably increased, and the camera can effectively operate in photon-counting 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 photon counting (PC) mode is the ideal solution to obtain high-quality images. By eliminating the excess noise factor (ENF) 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 photon-counting 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).
