Olympus have successfully developed an ergonomic new control section so that the tip of the device turns more linearly in relation to the patient while held by a physician. Additionally, they have made single-handed operation easier by improving the positions of the scope switches. These features contribute to improving the usability and insertion capability of both endoscopes. In addition to reducing the overall size of the control section as well as the universal cord diameter, Olympus reduced the weight of the control section by 30% compared to their conventional models. Both endoscopes feature the integrated NBI (Narrow Band Imaging).
