Optical resolution and color performance of electronic endoscopes.
We studied the optical and color performance of Olympus fiber- and electronic endoscopes, including the EVIS 100 and EVIS 200 series. The measurements showed that the optical resolution of new generation videoendoscopes equals or exceeds that of fiberendoscopes. The close-up focusing ability has been extended. The color performance of the new EVIS 200 gastroscope enables clear distinction of all mucosal hues.
