Toepassingen
Snelle Z-sectionering
Beweeg het objectief in plaats van het monster, zodat optische coupes zonder verstoring van levende preparaten worden doorlopen.
Autofocus en focusvolging
Houd de focus vast tegen thermische drift bij opnames van minuten tot uren.
Lichtvlak- en multifotonstapels
Neem Z-stapels op met een snelheid bepaald door de scanner, niet door het microscoopframe.
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.
Full series comparison, controller pairing and mounting hardware on the ambient piezo stages overview, or work through the selection with the configurator.
