We report the design and characterization of a 6 mm outer diameter pull-back circumferential scanning visible optical coherence tomography probe. The probe's large visible bandwidth (500-695 nm) allowed for inverse spectroscopic analysis and an axial resolution of ∼1.1 μm in tissue. We verify spectral imaging capabilities by measuring microsphere backscattering spectra and demonstrate in vivo spatial nanoscale characterization of tissue.
