High resolution imaging can be achieved with the EG-250WR5 and this is possible because of the 410K-pixel CCD which is contained in the narrow distal end. It has an ultra-wide 140 ° field of view which allows accurate and detailed images to be produced. Blood vessels can be observed better and routine examinations can be imaged excellently. The channel has a 2.8mm diameter and the slimmer 9.4mm diameter allows insertion and more extreme angulation.
