PolaSight SA, a University of Bern spin-off based in Lausanne, develops PolaOne: an AI-powered polarimetric imaging platform built for hospital pathologists. One button, 60 seconds, label-free, no consumables. PolaOne integrates into the intraoperative frozen-section consultation, the 20-minute pathology call during cancer surgery where misdiagnosis runs 30-40% in complex tissue. Serving the pathologist (captive user in a mandatory workflow), PolaOne avoids the surgeon-discretion trap of existing margin tools.
