Ultra-Flat Linear Stages feature 50 to 150 mm Travel

M-405.DG, M-415.DG Micropositioning Stages
Another highlight at LASER 99 was the introduction of the Active Drive option for the new M-400 Series of Translation Stages which replace the M-150 and M-155 stages (50 and 100 mm travel).

 New Active Drive featuring 0.125 µm resolution
   and 15 mm/s velocity
 Travel Ranges 50, 100 and 150 mm
 Stress-Relieved Aluminum Stage Base
   with integrated thermal Compensation for
   Highest Stability
 Crossed Roller Bearings
 High Resolution DC-Motor Drives
 Manual Knob for Convenient Position Adjustment
 Standard Origin and Limit Switches

These compact micropositioning stages are equipped with 0.5 mm pitch lead screws and crossed roller bearings providing high load capacity and excellent guiding accuracy. Two motorized versions are available: Models M-4xx.DG utilize closed loop DC motors with shaft mounted position encoders and backlash-free gearheads providing < 0.1 µm minimum incremental motion. Models M-4xx.PD are equipped with 30 Watt Active Drive DC motors providing 0.125 µm resolution and velocity up to 15 mm/sec. The novel Active Drive concept features an integrated, high efficiency power amplifier and reduces overall system cost, because the stage can be driven directly from a PC motor controller card (e.g. C-842).

 PI continues Growth
PI continues double-digit growth in the first two quarters of 1999. The growth also causes the continuing investment in new equipment and highly qualified people who help us meet our customers' needs. Here's an example of the importance of metrology test equipment in our quality control system: to date a total of six high resolution laser interferometers have been put to work at our headquarters in Waldbronn (plus a variety of other sophisticated optical and electrical instruments).
