QU EST-CE QU UNE CAMÉRA EMCCD? 9

PRINCIPALES CARACTÉRISTIQUES D UN DÉTECTEUR EMCCD 10

PRINCIPALES CARACTÉRISTIQUES D UN DÉTECTEUR EMCCD EMCCDs are mostly sensitive in the visible spectral range Quantum Efficiency over 90% from 500 nm to 650 nm 11

PRINCIPALES CARACTÉRISTIQUES D UN DÉTECTEUR EMCCD Detector architecture similar to frame-transfer CCDs Nüvü Caméras 12

PRINCIPALES SOURCES DE BRUIT DANS UNE EMCCD Bruit thermique Bruit d injection de charges (CIC) Excess Noise Factor 13

REFROIDISSEMENT DU DÉTECTEUR -85 C Nüvü Caméras 14

REFROIDISSEMENT DU DÉTECTEUR Diminuer la température du détecteur vient aussi affecter la capacité du détecteur à déplacer les charges de pixel en pixel. Nüvü Caméras EMCCD technology Typical EMCCDs -85 C cooling, 10 MHz readout speed EM gain of 5000 for Nüvü Caméras EM gain of 1000 for other EMCCDs 15

LINEAR MODE VS PHOTON COUNTING Qu est-ce que l excess noise factor? Quel est son impact sur la qualité de l image? Même effet sur le RSB que si l efficacité quantique diminuait de moitié COMMENT AUGMENTER ENCORE DAVANTAGE LE RSB? SOLUTION : UTILISER LE MODE COMPTAGE DE PHOTON (PC) 16

LINEAR MODE VS PHOTON COUNTING COMMENT ÉLIMINER L ENF? Threshold Lost events 17

PRINCIPALES SOURCES DE BRUIT DANS UNE EMCCD Bruit thermique -> Refroidissement avec cryostat unique Bruit d injection de charges (CIC) -> Électronique brevetée Excess Noise Factor -> Comptage de photons efficace 18

RECHERCHE BIOMÉDICALE AVEC NÜVÜ 21 NUVU CAMERAS INC 2015

BIOMEDICAL RESEARCH WITH NÜVÜ SMALL ANIMAL IMAGING The CCy5.5 fluorophore was injected intravenously to a concentration of 0.1 mg/ml. The colored zone shows the scanned area obtained by superposing fluorescence images to controls. NUVU CAMERAS INC 2015 22

BIOMEDICAL RESEARCH WITH NÜVÜ RAMAN IMAGING Raman imaging using a tunable Bragg filter with Nüvü s EMCCD technology is 60 times faster than conventional point-by-point mapping with standard CCD cameras. In-vivo and ex-vivo applications are now at reach, paving the way for real time tumor detection during surgery NUVU CAMERAS INC 2015 23

BIOMEDICAL RESEARCH WITH NÜVÜ PHARMACEUTICAL HYPERSPECTRAL IMAGING Detection of four membrane proteins with Quantum Dots and a synaptic marker on fixed hippocampal neurons (each image 75 X 45 µm) The possibility of acquiring hyperspectral data at the rate of 67 fps makes the Multiplex Microscopy Hyperspectral Imaging Platform a great tool to study rapid exchanges as those that occur in the central nervous system. Nüvü Caméras enhances rapid neuronal imaging platform for drug effectiveness assessment NUVU CAMERAS INC 2015 24
