Sub-nanometer precision motion products
now in UK
Exclusive UK distributorship for the 'Neat' range of photonics precision motion products from Danaher Precision Systems has been awarded to Heason Technologies Group
Exclusive UK distributorship for the 'Neat' range of photonics precision motion products from Danaher Precision Systems has been awarded to Heason Technologies Group of Chichester Targeted at the fibre optic and semiconductor markets, the Neat range includes both linear and rotary motion products and systems that offer accuracies to sub-nanometer and 2 micro-radians, respectively, with multi-axis system permutations ranging to X, Y, theta-x, theta-y and Z axes

Need to position precisiely in high vacuum?
Precision linear motion systems for ultra high vacuum conditions (UHV) have been introduced by Heason Technologies Group.
Many of the Neat linear motion range have non-contact, high stiffness air bearing guideways that permit both precision accuracy and high dynamic performance, helping to raise throughput to new levels.
Designed specifically for photonics and electronics applications, the Neat airbearings have zero friction, allowing rapid, exponential decay of following error to within nanometers of the target position, even with multi-kilogram loads and no travel limit.
Other stages benefit from the use of crossed-roller ways that give excellent stiffness, flatness and linear accuracy.
Maximising precision and performance, are direct drive, non-contact, brushless linear motors.
These provide essentially perfect translation between current and force, avoiding the friction, backlash and wear in screw driven stages.
Combined with linear encoders and 4096x interpolators sub-nanometer resolutions are achieved.
Neat's extremely compact direct drive rotary tables, with no gear, eliminate both torque variation and backlash problems.
They offer performances that include up to 10 revolutions/sec with resolution, repeatability and stability of only 2 micro-radians (0.4 arc seconds).
Because the motors employed are 2-wire, single-phase units they can be driven by any standard brush-type servo amplifier.
"Neat products fit naturally into our core business, complementing existing motion products whilst extending our system building capabilities to meet the increasingly demanding needs of our customers in the high precision photonics and semiconductor markets", said David Wheeler, Managing Director, Heason.
