high‐resolution mode
> 41,000 samples‐per‐step assists in low‐signal‐situations using electron beams

The M‐3000scanning system is the most efficient and accurate water phantom available on the market today. All the  components of the ARM scanner are either anodized aluminium or stainless steel, eliminating problems with corrosion. As a result, distilled or undistilled water can be used. High‐precision leads screws drive the scanner, which  is a superior design to timing belts. This design allows a precision of better than 0.1 mmfor all axis.   
Stepping motors drive the lead screws and a combination of software and firmware allows scanning with either  
stepping or continuous motion. The controller is housed in a convinent (LxWxH) 18 cm x 18 cm x 6 cm package. Dual amplifier, channel, and A/D converters are located inside the microprocessor, which controls the entire system. All electronics stay in the room and are connected to the remote computer via a thin serial line.
