Goniometer stage makes precise angular
motions
For precision applications needing small, angular motions, a goniometer stage enables extremely accurate angular alignment of for example optical components such as fibre couplings and arrays.

Aerotech has introduced a revised section in engineering reference, which covers Vacuum Preparation for motion control specific applications.
Aerotech motion systems described for automation
Motion systems for automatic laser working, medical and life sciences manufacturing systems are described in Aerotech's Automation Solutions brochure, also available in German.
Using direct drive linear motor technology, Aerotech defies logic with a linear motor that provides incredible repeatability of ñ0.05 arc-seconds and gives a 20ø angular motion that is accurate to an impressive 10 arc-seconds.
When used with Aerotech's MXH multiplier, the ANT-20G stage provides a positioning speed of 150deg per second, even at 0.058 arc-second resolution.
The resolution is improved still further to an amazing 0.0018 arc-seconds when the ANT stage is driven by Aerotech's new Automation 3200 software only motion controller.
Linear encoder feedback is used to ensure an exceptional position reference.
The non-contact, non-cogging direct drive technology gives a higher frequency response and unlike worm or piezo-drive stages, the ANT-20G does not require periodic adjustment or maintenance.
This represents a significant step towards trouble free operation that is matched by ease of installation.
A benefit is the small size of the ANT goniometer which measures 95mm x 81mm x 38mm and features high precision ball bearings enabling loads up to 1.5kg.
The critical elements of the ANT-20G goniometer, as with all other ANT series nano-positioners, were selected to operate in a 24/7 manufacturing environment.
A range of direct drive rotary stages, Aerotech's ADRT Series, are also available. Request a free brochure from Aerotech ...
