The EVIS EXERA II CF-H180AL/I colonovideoscope is HDTV-compatible, delivering the highest-possible resolution and image quality. It comes equipped with an impressive suite of advanced functions, including Narrow Band Imaging (NBI) to enhance visualization of mucosal tissue and capillary structures. A Close Focus function produces the same effect as electronic magnification simply by bringing the scope tip close to the observation area. A generous 3.7 mm diameter channel (12.8 mm diameter insertion tube) accommodates a wide range of endoscopic devices while maintaining suction capability.
