Open-top light-sheet (OTLS) microscopy has recently been developed as a high-throughput, easy-to-use 3D microscopy technique for large specimens [1-2]. The oblique angle of the optical beams relative to the sample plate introduces challenges however, and previous solutions (such as a solid immersion lens) have been limiting [1]. Therefore we have developed a solid immersion meniscus lens (SIMlens), which enables optical beams to transition from air to a higher-index immersion medium without introducing aberrations [3]. A SIMlens is compatible with a turret of air objectives, enabling efficient multi-resolution workflows [4]. We present the first multi-resolution OTLS microscope, enabled by a SIMlens.
