μManager is a software package for control of automated microscopes. It lets you execute common microscope image acquisition strategies such as time-lapses, multi-channel imaging, z-stacks, and combinations thereof. μManager works with microscopes from all four major manufacturers (Leica, Nikon, Olympus and Zeiss), most scientific-grade cameras and many peripherals (stages, filter wheels, shutters, etc.) used in microscope imaging. Since μManager runs as a plugin to ImageJ, image analysis routines are available within the application. μManager software is available for multiple platforms (Windows, Mac, and Linux) and is free.
