The Pitch-and-Roll positioning stages are used to do micro machining, align mirrors for scanning electron microscopes, rotate objects to precise positions, measure angles of objects such as crystals or move an object to a precise angular position along an arc, examining cutting edges of medical instruments, estimating measurements of radiation patterns of LEDs, hyper spectral bidirectional reflectance, or provide orthogonal rotation.

OES offers a series of Pitch-and-Roll Stages to meet the requirements of the specific requirements of applications such as:  Angle range - 20 Deg. (± 10  Deg.), 30  Deg. (± 15  Deg.), and 90  Deg. (± 45  Deg.), height of rotation, size (foot print), and load capacity.  Typical accuracies for each stage are: Repeatability: ± 4 minutes (240 arc-seconds), positional accuracy ± 8 minutes (480 arc-seconds), and backlash ± 3 minutes (180 arc-seconds).   

The precision, Pitch-and-Roll Stages are available with either stepper motors with knobs for manual adjustment, or quadrature optical encoders on stepper motors for position verification. They are also available servo motors for closed loop operation and higher operating speed. The Pitch-and-Roll Stages can be supplied plug-and-play with a Motion Controller . Any of the Stacked Pitch-and Roll Stages are easily integrated into an inspection, testing, or manufacturing environment.
