Novel broadband freeform micro-optics for multimodal FLIm-OCT intravascular catheter (Conference Presentation)
Author(s): Julien Bec; Cai Li; Laura Marcu

Paper Abstract

Fluorescence Lifetime Imaging (FLIm) is a label-free technique that reveals extracellular lipid and foam cells accumulation within atherosclerotic lesions, complementing the structural information provided by Optical Coherence Tomography (OCT). Successful intravascular implementation of FLIm-OCT requires high optical performances for both single and multimode beams, spanning the near UV to near IR range, out of reach of the current miniature optics (ball or gradient index lenses). Here, we present a 0.3 x 0.3 x 0.8 mm3 monolithic freeform optic that provides high optical performances over the UV-IR range (355-1360 nm), enabling high-performance intravascular FLIm-OCT imaging catheter designs.
