我们已经设计并实现了一个紧凑的,具有成本效益的,基于光学微机电系统扫描仪和可调透镜的单片光片显微镜系统。该系统占地面积为20 × 28 × 13 cm 3,将现成的光学和光学机械与3D打印的结构和光学元件以及经济成本的物镜透镜、激发激光器和相机相结合。全光学体积扫描可实现435 × 232 × 60 µm3体积的成像,速度为0.25 vps(体积/秒),最小横向和轴向分辨率分别为1.0 µm和3.8 µm。顶部开放的几何形状允许在平底支架上对样品进行成像,允许与微流体装置、多孔板和载玻片安装样品集成,并在生物医学研究和临床前环境中应用。
We have designed and implemented a compact, cost-efficient miniaturised light-sheet microscopy system based on optical microelectromechanical systems 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 435 × 232 × 60 µm3 volumes with 0.25 vps (volumes per second) and minimum lateral and axial resolution of 1.0 µm and 3.8 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.
