Princeton Instruments’ KURO camera is the world’s first scientific CMOS (sCMOS) camera system that employs back-illuminated sensor technology. CCD camera systems have almost exclusively leveraged this key technology until now; however, in spite of their outstanding sensitivity, these CCD camera systems are not able to match CMOS frame rates. Front-illuminated CMOS cameras, meanwhile, cannot address the high-sensitivity requirements of today’s spectroscopy and ultra-low-light scientific imaging applications.
KURO cameras provide outstanding sensitivity and fast frame rates necessary for applications such as quantum imaging, cold-atom imaging, hyperspectral imaging, astronomy, fluorescence spectroscopy, and high-speed spectroscopy, all without the drawbacks commonly prevalent in front-illuminated sCMOS cameras.
Fluorescence, Phosphorescence and Photoluminescence Spectroscopy
Fluorescence, phosphorescence and photoluminescence take place when a sample is excited by absorbing photons and then emitting them with a decay time that is typical of the sample environment.
Generally astronomical imaging can be classified into two categories: (1) steady-state imaging, where long exposures are necessary to capture ultra-low-light-level objects, and (2) time-resolved photometry, where the integration time ranges from milliseconds to a few seconds.
