Abstract
We have designed and implemented a compact, cost-efficient miniaturised light-sheet microscopy system based on optical Microelectromechanical Systems (MEMS) scanners and tunable lenses. The system occupies a footprint of 20 × 28 × 13 cm3 and combines off-the-shelf optics and optomechanics with 3D-printed structural and optical elements, and an economically costed objective lens, excitation laser and camera. All-optical volume scanning enables imaging of 340 × 190 × 60 µm3 volumes with 0.25 vps and minimum lateral and axial resolution of 0.9 µm and 2.95 µm respectively. An open-top geometry allows imaging of samples on flat bottomed holders, allowing integration with microfluidic devices, multi-well plates and slide mounted samples, with applications envisaged in biomedical research and pre-clinical settings.
