Applications
Tip/tilt around a sample plane
Correct sample tilt without translating the point of interest out of the field.
Incidence angle control
Set the angle of incidence for reflectometry, ellipsometry and grazing-incidence work.
Optic alignment
Square a mirror, grating or detector to the beam where a fixed pivot keeps the geometry intact.
Specifying this part
What this model has to survive, and what it needs around it
Tilt about a point above the plate
Each goniometer tilts about a centre a fixed height above its own mounting surface, so a theta and phi pair share one virtual pivot. Get that height right against your sample plane or the beam walks as you tilt.
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.
