Featuring Back-Illuminated EMCCD technology, the QImaging® Rolera Thunder is designed for extreme low light imaging applications. Many applications including TIRF microscopy, single molecule fluorescence and live-cell fluorescence emit light levels that are too low for standard CCD cameras to image at reasonable frame rates.
