The basic differences are in the number of channels for excitation (5 versus 7), the ability to image in brightfield, widefield, and confocal, and the number of positions available on the objective turret. The CellInsight CX5 System is the most basic HCS system with illumination in 5 channels, imaging in brightfield and widefield, and a 1-position objective turret. The CellInsight CX7 System and ArrayScan System provide illumination in 7 channels, imaging in brightfield, widefield, and confocal, and either a 3-position (CX7) or 4-position objective turret (ArrayScan System). The ArrayScan System has the added option of live-cell imaging.
