12 Dec 2007 Micro- and nanopositioning specialists Physik Instrumente (PI) have introduced a family of 48 motorised translation stages based on a modular design. The stages can be produced with different combinations of base profiles, motors and spindles with seven different lengths covering the range 25mm to 300mm of travel. Depending on the required accuracy and controller type, the stages can be equipped with one of three available motors. The motors in the range are a low-cost stepper motor, a DC motor and gearbox, or, for highest accuracy, the proven ActiveDrive direct-drive DC motor.
To simplify selection the 48 versions of the stages are divided into four series. The M-403 range contains the basic models with up to 200mm of travel, the M-413 range is more robust carrying heavier loads and offers travel ranges up to 300mm. The M-404 and M414 series carry the same heavier loads over 300mm of travel but offer higher precision. The least precise M-403/M-413 stages have a step size as small as 0.2µm. The M-404/M-414 models use low-friction recirculating ballscrew drives with high precision guidance to achieve 0.1µm steps. As heavier duty units, the M-413 and M-414 stages have a 50% wider and higher base profiles than the M-403/M-404 models. This provides the greater stability required in the positioning of heavier loads.
A cost-effective single channel servo controller is available, the C-862 Mercury. For applications where several independent axes are required, up to six Mercury controllers can be networked. Co-ordinated control of up to four axes is offered by the convenient C-843 servo controller in a PCI-board format.
