First fingerprint SRS image

IF-CNRS CRIMSON team evaluated SRS imaging in the fingerprint on a cancerous brain tissue sample. The SRS signal is x15-x20 less than in the lipid region but sufficient to perform imaging.

Two wavenumbers imaging: 1350cm-1 (blue) and 1450cm-1 (magenta)
Image size: 0.8mm x 0.8 mm
60ms pixel dwell time – 10 minutes acquisition time
