Multi-Immersion Lenses for Cleared-Tissue Imaging

Presentation will begin: Tuesday, October 25, 2022 - 9:50 AM EDT
Presented by: Jon Daniels, Applied Scientific Instrumentation

A simple design trick enables an objective lens to work in any dipping medium, unlike other multi-immersion objectives with limited refractive index range. Daniels describes the design trick and its benefits, particularly for light-sheet imaging of cleared samples. He will also show existing and upcoming objective lenses that take advantage of this concept, including a recent design that achieves NA 1.23 in dibenzyl ether (refractive index 1.56) with 3.4-mm working distance.
