The FiberBeam family of linear motor positioners are designed to meet the demands of photonic alignment and assembly systems.
With travel of 20, 50, and 100mm, all share a low profile of 50mm.
The Fiberbeam stages themselves incorporate proprietary porous bearing technology, avoiding the clogging problems common to orifice bearing designs.
All models bolt together directly to form X-Y assemblies without the need for adapter plates. The height of such a stack is 100mm. Right angle brackets and frictionless spring or air counterbalances are available to permit vertical operation. This allows three axis X-Y-Z assemblies to be configured.
Dual carriage/single base versions can also be supplied, where the motion of the two carriages is parallel to less than 2 arc-seconds.
In constant velocity applications, tracking errors during motion can be held to +/- 10 nanometres.
The use of a single phase, brush-less motor in the FiberBeam-20 stage provides the high performance of sinusoidal commutation from brush-type amplifiers – no commutation is required.
All the cables and connectors are located in a stationary base, avoiding any cable influence on stage movement.
