Abstract
With the use of state of the art light microscopy methods, we can image the tissue with sub-cellular resolutions down to 1.5 mm. Beyond this reach, the light must be delivered to the target region by optical relay elements inserted into the tissue – the fibre endoscopes. With fibre micro-endoscopes, we can reach depth down to 5 mm (mostly the bottom of a living mouse brain) with negligible tissue disruption and keep the resolution equal to 1 micrometre, still sufficient for in vivo microscopy. We designed a custom-made device for optical fibre tips machining. The presented poster will focus on optical fibre probe manufacturing (stripping, etching, polishing and coating) and on their impact on imaging quality and performance.
