PR50 Series Compact High-Speed Rotation Stages
2.0 —Description
The PR50 Series low profile rotation stages are designed to rotate up to
1
in. diameter optical components, such as polarizers, wave plates, or
wedges. The small size (only 60 mm width x 110 mm length x 21 mm
height) allows use in confined spaces such as laser cavities, disk texturing
machines, or manufacturing areas for optical components.
Similar to our higher-resolution rotation stages SR50, the PR50 stages feat
ure a low-profile, lightweight design based on an aluminum body construction with preloaded ball bearings. The motor is folded inside the outer
body providing a small footprint.
The PR50 stages are a cost-efficient alternative to the SR50 for applications
that do not require the high-resolution and precision of the SR50, or for
applications that could benefit from higher speeds up to 20 °/s. The stages
feature angular resolution of 0.01°, which may be achieved with either DCServo or open-loop stepper motors in half-step mode. The stages are
equipped with a hardware origin and allow for continuous rotation of 360°.
For optimal performance, we recommend the use of our motion controllers.
The PR50 rotation stages are equipped with a 3-meter cable for connection
to our motion controllers.

3.0 —Characteristics
3.1 Definitions
Specifications of our products are established in reference to ISO 230
standard part II “Determination of accuracy and repeatability of
positioning numerically controlled axes”.
T
his standard gives the definition of position uncertainty which depends
on the 3 following parameters:
Absolute Accuracy
Difference between ideal position and real position.
Accuracy
Difference between ideal position and real position after the compensation
of linear errors.
Linear errors include: cosine errors, inaccuracy of screw or linear scale
pitch, angular deviation at the measuring point (Abbe error) and thermal
expansion effects. All Newport motion electronics can compensate for
linear errors.
The relation between absolute accuracy and on-axis accuracy is as follows:
Absolute Accuracy = Accuracy + Correction Factor
x Travel
Repeatability
Ability of a system to achieve a commanded position over many attempts.
Reversal Value (Hysteresis)
Difference between actual position values obtained for a given target
position when approached from opposite directions.
Minimum Incremental Motion (MIM or Sensitivity)
The smallest increment of motion a device is capable of delivering
consistently and reliably.
Resolution
The smallest increment that a motion device can theoretically move
and/or detect. Resolution is not achievable, whereas MIM, is the real
output of a motion system.
Eccentricity
Displacement of the geometric center of a rotation stage from the rotation
axis in the plane defined by bearings.
Wobble
Tilt of rotation axis during rotation of a stage, measured on a reference
surface.
The testing of accuracy, repeatability, and reversal error are made
systematically with test equipment in controlled environment (20±1°C).
A linear cycle with 21 data points on the travel and 4 cycles in each
direction gives a total of 168 points.

5.5 Mechanical Zero
Mechanical Zero is a 5 V open collector type.
Mechanical Zero repeatability is <0.01°.
CAUTION
“Mechanical Zero” is an active signal and should not be connected to any
other source.
5.6 Feedback Signal Position (PR50CC Only)
The incremental sensor consists of an optical scale and an encoder head.
When the carriage moves, the encoder head generates square signals in
quadrature and sends to pins #19, #20, #23 and #24 of the SUB-D25
connector.
“Encoder” are “differential pair” (type RS-422) type output signals. Using
these signals permits a high immunity to noise. Emission circuits generally
used by Newport are 26LS31 or MC3487. Reception circuits to use are
26LS32 or MC3486.
