EDOF™ endoscopes – the GIF-EZ1500 gastroscope and the CF-EZ1500DL/I colonoscope – represent Olympus’ most advanced imaging and latest innovation as part of the EVIS X1™ endoscopy system. By allowing physicians to obtain sharp images, EDOF technology allows an entire lesion to be kept in focus and may aid in detection as endoscopists inspect the mucosal lining of the GI tract.
EDOF technology creates an image in total focus by using two prisms to split light entering the endoscope lens into two separate beams with near- and far-focused images. Those beams are then projected simultaneously onto an image sensor, combining them into one image with a wide depth of field.1
Compared to the previous generation of Olympus® scopes, this technology provides improved visibility and less blurring. The EZ1500 series EDOF scopes allow for closer distance in normal mode compared to the CF-HQ190L/I – 3mm vs. 5mm – without blurring, limiting the need to switch from normal to near mode.
