AOS News Volume 25 Number 1 2011ProEM: The No-compromise Electron-Multiplying CCD CameraPrinceton Instruments has releasedProEM, the highest performanceEMCCD camera to be offered onthe scientific imaging market to date.ProEM cameras are designed to addresschallenging low-light applicationsassociated with single-moleculefluorescence, astronomy, and ionimaging, as well as many other highframe-rate,light-starved applications.Verdi G-SeriesVerdi is a family of compact, diodepumpedsolid-state (DPSS) and opticallypumped semiconductor (OPS) laserswith continuous-wave 532nm lasersand offers the broadest output powerrange of up to 18W, as well as 25Wof 1064nm. Used primarily in Ti:Soscillator pumping applications, moreProEM uses 512x512 and 1024x1024back-illuminated EMCCD’s andsupports both electron multiplication(EM) and traditional readout ports.The EM port is used when high framerates are required under low-lightconditions, while the traditional readoutport is ideal for slow-scan applications.The cameras include several highlyinnovative features to ensure the highestpossible bias stability and lowest noise,while the new OptiCAL feature providesEM gain calibration on demand. ProEMalso provides a hardware-generatedtimestamp on each frame to takethe guesswork out of time-resolvedphotometry, and a Gigabit Ethernetinterface allowing the camera to beoperated remotely.than 6,000 Verdi lasers have beeninstalled world-wide. Verdi lasers enablesuperior system performance in a widerange of ultrafast applications with thehighest power and lowest noise (
