LS850 Microscope
The LS850 offers a whole new world of automated microscopy.

Blue, Green, and Red Fluorescence and Walk-Away Automation

The powerful LS850 Microscope represents the latest generation of our fully automated three-channel flagship model. It introduces advancements in optics, cameras, throughput, and user flexibility. The LS850 enhances image quality, motion speed, illumination, and software flexibility over the previous LS720 model. Notable features include exquisite XY motion control, motorized focus enabling autofocus and Z-stacks, and easy-to-configure software for seamless automated microscopy experiments.

The LS850 in your incubator allows you to have a live cell imaging system that offers minimum photo toxicity and the most stable environment for long-term imaging.

Whether imaging multiple fields in your flasks or 1536 wells of cells with three fluorophores in a multi-day time-lapse, the LS850 opens up a new realm of walk-away automated microscopy!
