In order to minimize any effects that fluorophores may themselves make on the system being studied, many bio-researchers are seeking to reduce the concentration of fluorescent molecules used to label samples. Some researchers have chosen to track events at the single-molecule level.
Several years ago, Photometrics broke exciting new ground with the world's first commercially available EMCCD camera designed for microscopy. Today, Photometrics continues to lead the way in the evolution of this technology. Current offerings in the Photometrics line of EMCCD cameras boast greater than 92% peak quantum efficiency, 16-bit digitization, and the lowest noise levels in the industry. Using Photometrics camera technology, researchers can follow single molecules at speeds greater than 500 full frames per second.
