New CCD-based Technology for Improved Chemiluminescent and Fluorescent Detection

March 3, 2011, Lincoln, NE: FieldBrite imaging technology from LI-COR Biosciences represents an advancement in CCD-based imaging technology. It offers researchers excellent sensitivity and a wide linear dynamic range with uniform field illumination. LI-COR uses FieldBrite™ technology in its Pearl® Impulse Small Animal Imaging System and the Odyssey Fc Imaging System. FieldBrite technology is used for detection at near-infrared fluorescent wavelengths, and now, with the Odyssey Fc Imager, for detection of chemiluminescent signals.

"The researcher's data benefit from uniform area illumination so there's no need to worry about where in the field the sample is placed and no need for software adjustments," says Jeff Harford, LI-COR senior marketing product manager. "FieldBrite dramatically increases sensitivity by reducing noise without the need to supercool the camera."

Patented FieldBrite technology delivers 22-bit dynamic range, which ensures perfect data, immediately accessible for qualitative and quantitative analysis at the very first image acquisition. Strong and weak signals are detected without saturation as with other CCD-based imaging systems. Repetitive and time consuming film exposures or traditional CCD camera systems are no longer required. The FieldBrite technology employed in the Odyssey Fc provides chemiluminescence imaging without overexposure or saturated bands, without the need for multiple exposures.
