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.
The lower goniometer stage features
± 10
degrees of rotation at a rate of 14
degrees
per second with stepper motor and 90 degrees per second with Three Phase Brushless Servo Motor with Quadrature Incremental Optical Encoder. The upper goniometer stage features a 120 mm x 120 mm table,
± 15 degrees of rotation at a rate of
14
degrees per second with stepper motor and 90 degrees per second with Three Phase Brushless Servo Motor with Quadrature Incremental Optical Encoder. The accuracies for each unit are; repeatability:
± 4" (240 arcseconds), typical Positioning accuracy: ± 9" (540 arcseconds), and typical backlash is ± 3" (180 arcseconds).
The goniometers and 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.
The precision, compact AK150-10-15 Goniometer stacked stage, available with either stepper, Three Phase Brushless Servo Motor with Quadrature Incremental Optical Encoders, optical encoders or manual adjustment knobs. It has a footprint of just 169 mm x 169 mm, and can be supplied plug-and-play with a motion controller. It is easily integrated into an inspection, testing, or manufacturing environment.
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.
