The KURO cameras from Princeton Instruments is the world’s first scientific CMOS (sCMOS) camera system implemented with back-illuminated sensor technology. Until now, CCD camera systems has almost exclusively leveraged this key technology. However, despite their excellent sensitivity, these CCD camera systems cannot match CMOS frame rates. Meanwhile, front-illuminated CMOS cameras are unable to address the high-sensitivity requirements of today’s ultra-low-light scientific imaging and spectroscopy applications.
With exceptional sensitivity and fast frame rates, KURO cameras can be used for applications such as high-speed spectroscopy, fluorescence spectroscopy, quantum imaging, cold-atom imaging, astronomy and hyperspectral imaging, all without the drawbacks prevalent in front-illuminated sCMOS cameras.
Fluorescence, Phosphorescence and Photoluminescence Spectroscopy
Fluorescence, phosphorescence and photoluminescence take place upon excitation of a sample when it absorbs photons and then emits them with a decay time that is characteristic of the sample environment.
Astronomical imaging can be broadly classified into two categories: (1) steady-state imaging, which requires long exposures to capture ultra-low-light-level objects, and (2) time-resolved photometry, in which the integration time range is from milliseconds to a few seconds.
