Full Focus and High Magnification for Observational Excellence

EDOF Technology

Our unique Extended Depth of Field (EDOF) technology combines images captured in near view with those taken in far view to generate an image with a wider depth of field that gives you greater clarity and richer detail throughout the image area, assuring superior observation with continuous wide focusing.

Full Focus

Thanks to EDOF technology, the GIF-EZ1500 can approach as close as 3 mm to the subject in normal focus mode, providing a clear, sharp view that may reduce the need to adjust the focus in routine use.

High Magnification with the Ease of Dual Focus

The GIF-EZ1500 offers high magnification* when the Near Focus mode is engaged via a simple scope switch, supporting better observation of details. The combination of high magnification and wide depth of field allows for clearer, more detailed imaging throughout the field of view, even from a tangential direction and regardless of whether the subject is moving or not. In combination with proven NBI technology, the GIF-EZ1500's advanced optics is designed to assist accurate, high-confidence optical diagnosis.

* Maximum magnification of 85x (with OEV262H) and 100x (with OEV321UH).
