The precise
measurements
of angles
and the
curvature of
objects are
easily
determined
using OES'
Pitch and
Roll Stages.
The Pitch
axis (lower
stage) is a
high
precision
goniometer
stage which
features
preloaded
cross roller
guides and a
1 to 296
ratio worm
drive for
smooth
motion over
a range of
travel of
+/- 45
degrees and
has a
typical
accuracy of
0.05 degrees
and
repeatability
of +/- 0.01
degrees.
The roll
axis (upper
stage) is
also a high
precision
goniometer
stage
featuring
preloaded
cross roller
guides and a
1:352 gear
ratio worm
drive for
smooth
motion over
a range of
travel of
+/- 10
degrees.
This stage
has a 65 mm
x 65 mm
table and
also has a
typical
accuracy of
0.05 degrees
and
repeatability
of +/- 0.01
degrees.
Additionally,
each axis
has
end-of-travel
limit
switches.
The
PR120-45-10-01
and the
PR120-45-10-04
which has
Optical
Encoders for
position
verification,
are both
stepper
motor
driven. The
PR120-45-10-02
is driven by
Three Phase
Servo motors
and the
PR120-45-10-03
is driven by
DC Servo
motors; and
each have
Quardrature
Incremental
Encoders for
the higher
speeds,
resolution,
and
repeatability
of closed
loop servo
systems.
Each axis
features an
adjustable
calibrated
scale to
visually
display the
angle of
rotation.
The maximum
speed with
stepper
motors is 14
degrees/second
and 45
degrees/second
with servo
motors. The
resolution
of the
PR120-45-10
stepper
motor driven
duel-axis
stage
depends on
the
resolution
of the
stepper
motor driver
resolution
or the
optical
encoder if a
servo motor
is used. A
resolution
of 0.001
degrees
equivalent
to 3.6
arc-sec can
be achieved
using a 10
micro-steps
per step
stepper
motor driver
or an
encoder with
a resolution
of 500
cycles per
revolution.
The
Dual-axis
Pitch and
Roll Stages
require a
Motion
Controller
that can be
ordered as a
complete
plug-and-play
system with
joystick,
trackball,
and keypad. |
