| | | The LDS-1000 Laser Doppler Scale (LDS) provides high speed, high accuracy and long range positioning for single or multiple axis applications, such as linear motors suppliers, large gantry machines, CNC center tools, CMM's, precision stages, supermicrometers and other linear measurement devices. Based on the Laser Doppler Displacement Meter (LDDM), the LDS is compact, easy installation, easy alignment, less Abbe offset, no cross coupling, high accuracy, high speed and cost effective. Supplying automatic temperature compensation, home position, TTL AQuadB squarewaves, Up/Down pulses or sinusoidial output, the LDS is compatible with all mainstream controller feedback systems. The LDS has been installed in many high performance machine tools. It is insensitive to dirt, oil and hostile environments. | | The LDS provides a high degree of accuracy including automatic environmental compensation, such as air temperature, barometric pressure, and machine/material temperature. Laser stability check is better than 0.1 PPM. Typical system accuracy is 1.0 PPM and resolution is up to 0.002 |im. Range is up to 50m. | | |
