Applications
Fast Z-sectioning
Move the objective instead of the sample, so optical sections can be stepped without disturbing live specimens.
Autofocus and focus tracking
Hold focus against thermal drift over acquisitions lasting minutes to hours.
Light-sheet and multiphoton stacks
Acquire Z-stacks at a rate set by the scanner rather than by the microscope frame.
Specifying this part
What this model has to survive, and what it needs around it
Driving the objective rather than the sample
Moves the lens along the optical axis for focus stacks and z-series, leaving a liquid sample or mounted cell undisturbed. Travel options run 100, 200 and 400 µm; settling time rather than range is usually the limiting specification.
Vacuum and non-magnetic versions
Most of the range is orderable as .HV (high vacuum), .UHV (ultra-high vacuum) or .NM (non-magnetic). The suffix changes materials, cabling and bake compatibility rather than the mechanics, so specify it against the chamber the stage will live in.
