Goniometer
stages
can
measure
angles
of
objects
such
as
crystals
or
move
an
object
to a
precise angular position along
an
arc,
in
relation
to a
fixed
point
in
space.
Two
goniometer
stages
mounted
in
an
alpha-beta
configuration
(stacked)
can
rotate
an
object
around
a
fixed
point
in
space on
a
spherical
surface.
Both
goniometer
stages
feature
+/-
45
Degrees
of
rotation
at a
rate
of
14
Degrees
per
second
with
stepper
motor
and
90
Degrees
per
second
with
Servo
Motors.
The
upper
goniometer
stage
features
a
104
mm
by
90
mm
table.
The stacked goniometers are used for: Identifying crystals, examining cutting edges of medical instruments, estimating hyperspectral bidirectional reflectance, gloss measurements, measurements of radiation patterns of LEDs, Directing lasers, aligning mirrors, and manufacturing of quartz oscillator plates using quartz cutting x-rays.
This
series
is available with either stepper, Three Phase Brushless Servo Motor with Quadrature Incremental Optical Encoders, optical encoders or manual adjustment knobs.
This stage requires a
Motion Controller
that can be ordered as a complete plug-and-play system with RS-232, USB, joystick and keypad control.
