Neuroscience 2026, the annual meeting of the Society for Neuroscience (SfN), takes place from 14 to 18 November 2026 at the Walter E. Washington Convention Center in Washington, DC. Phaseform is at the booth of our US distribution partner Aladdin Optics: booth 1028. The exhibit hall is open from 15 to 18 November, and our CEO Stefan M. Weber is at the booth from Sunday 15 to Tuesday 17 November.
What we show
Visit us and see how little it takes to add adaptive optics to a microscope you already use. We demonstrate it on a widefield microscope: our Deformable Phase Plate (DPP) sits right at the objective's exit pupil and corrects wavefront aberrations. It needs no wavefront sensor and no folded mirror relay.
Meet us in Washington
If you run a two-photon, three-photon, light-sheet or widefield setup and lose signal or detail in tissue, we look forward to talking with you. Come to booth 1028, or write to us ahead of your visit.
Six examples in brain tissue
The clip shows what the correction does in brain tissue. In each of the six examples the slider moves from adaptive optics off to adaptive optics on.
