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, trackball, and keypad control.
