Two-photon endomicroscopy is a promising technique with the ability to achieve in situ imaging and diagnosis at subcellular resolution. The large field-of-view capability is essential and useful to locate and image suspicious areas of biological tissue. In this work, we report objective-lens-free, lensed fiber-optic two-photon endomicroscopy for field-of-view enhancement. The field of view of this two-photon endomicroscopic probe is 750 μm with a resolution of 3.03 μm. This 1.6 g miniature probe has an integrated outer diameter of 5.8 mm and a rigid length of 33.5 mm. The imaging performance of the lensed-fiber-optic two-photon endomicroscopy was validated by examining an ex vivo mouse heart, kidney, brain, stomach wall tissues, and in vivo brain tissue.
