Applications
Polarisation-dependent measurement
Rotate waveplates, polarisers and samples through controlled angular steps.
Sample orientation
Bring a facet, crystal axis or device feature to the measurement angle and hold it there.
Angle-resolved scattering
Drive azimuthal sweeps where angular repeatability sets the quality of the dataset.
Specifying this part
What this model has to survive, and what it needs around it
Rotary resolution sits well above the linear axes
Rotary encoders read to around 50 nm equivalent rather than the 2 nm of the linear stages. If angular repeatability drives the measurement, check it against the encoder figure rather than assuming the linear specification carries across.
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.
