Nanomover Micropositioning (Applied Precision) This Nanomover II micropositioning system can control from 1 to 8 actuators simultaneously. The Nanomover actuators perform specified levels of precision when operated with Nanomover software and the Nanomover II electronics assembly (chassis) . Actuators can be controlled through an IBM ISA bus, or an RS-232 or IEEE-488 interface. The Nanomover software is user friendly and only a cursory knowledge of personal computers is necessary ( Dins are 9.5’s, and uses 25mm actuators) . The ultimate resolution of the Nanomover is 81 microstep.With 50,000 microsteps per revolution and a 2 threads per millimeter pre- cision micrometer lead screw, this is a resolution of 10 nanometers. In most applications, the most important feature of a micro- positioning device is the ability to return to a position with consistently high accuracy. The Nanomover has an unsurpassed Using the Park function, the system can be powered down and left overnight and will still return to the same position within 100 nm. Good accuracy is hard to achieve but is rarely as important as repeatability, since, in principle, compensation can always be made for systematic deviations. The Nanomover has an absolute accuracy of travel of 81 mm, which arises from minute variations in the micrometer thread pitch and inherent inaccuracies present in the stepper motor. For applications requiring even higher accuracy, a software routine can be supplied ( Melles Griot or Applied in Isaqua) to compensate for the errors in an individual lead screw. The Nanomover actuators are able to achieve their high degree of resolution, accuracy, and repeatability over a total range of 25 mm. A Nanomover system can be operated directly from an IBM PC or industry standard IEEE-488 or RS-232 interfaces. Systems with more than two actuators can be created by cascading in one of three ways: via the IBM-ISA bus, the parallel IEEE-488 bus, or the RS 232 serial interface. The Nanomover software and associated algorithms are vital in achieving specified performance. The IBM-compatible system can be controlled using Nanomover application software and can be programmed using any Windows-compatible programming language with the Nanomotion dynamically linkable library (DLL). The Nanomotion IEEE-488 system can be controlled using the LabVIEW drivers or by programming directly with IEEE-488 commands. Use the FREE Counters 1 million sellers do - Andale! |
