In this study, a new flexible contact endoscope that is similar to a fiber-optic ultrathin endoscope is examined. Using a new optical design with a 0.23 pitch gradient index lens and an ultrathin fiber-optic image guide, we have obtained 228 line pairs/mm ultrahigh-resolution images. The resolution and magnification of the obtained images are measured and analyzed. Also, the relationship between magnification and the working distance from the target to the gradient index (GRIN) lens using GRIN lenses of different pitch lengths is determined. Finally, we have taken an image of red blood corpuscles of 6–9 μm average size.
