A new focused OCT-LIF endoscope has been constructed for high resolution imaging between 325 nm and 1300 nm. This endoscope is 2 mm in diameter for non-destructive imaging in vivo. A reflective design ball lens is employed that eliminates the difficulty of operating achromatically over a large range, while taking advantage of TIR at two faces and coating a third mirror face internally to focus the beams downwards. It is a 1:1 imaging system that obtains a theoretical diffraction-limited resolution for both the OCT (800-1300 nm) and LIF (greater than 325 nm) channels.
