Stage drives flat motors round the bend
Aerotech's ANT-20G goniometer stage enables extremely accurate angular alignment of optical components such as fibre couplings and arrays.
Aerotech's ANT-20G goniometer stage enables extremely accurate angular alignment of optical components such as fibre couplings and arrays. Indeed, any precision application needing small, angular motions, can be met by the ANT stages. Using direct drive linear motor technology, Aerotech defies logic with a linear motor that provides incredible repeatability of +/-0.05arc-sec and gives a 20-degree angular motion that is accurate to an impressive 10arc-sec.
When used with Aerotech's MXH multiplier, the ANT-20G stage provides a positioning speed of 150 degrees per second, even at 0.058arc-sec resolution.
The resolution is improved still further to an amazing 0.0018arc-sec 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 noncontact, noncogging direct-drive technology gives a higher frequency response and unlike worm or piezodrive 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 95 x 81 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 nanopositioners, were selected to operate in a 24/7 manufacturing environment.
