Laser Doppler Displacement Meter

Linear Machine Calibration

OPTODYNE's MCV-500 Compact Linear Machine Calibration System, calibrates CNC machine tools, CMM's (Coordinate Measuring Machines), and other precision measuring machines and stages.

This new compact calibration system, based on the patented Laser Doppler Displacement Meter (LDDMT"') technology, is designed for easy setup and operation. The basic system, including Windows''' software, automatic compensation, (compensates for air temperature, barometric pressure, and material thermal expansion) and accessories are packaged at an extremely affordable price. The system is very compact and fits in one small carrying case.

The WindowsTM software, running on any IBM compatible computer, is user friendly and is designed to collect and analyze data in accordance with a variety of industry standards, such as NMTBA, VDI, ISO and ASME B5.54. The laser system is calibrated and traceable to NIST.


•  Compact and light-weight
•  Easy to setup and operate
•  Automatic data collection
•  NIST traceable laser accuracy
•  No tripod and no interferometer
•  WindowsTM' software
•  USB (RS-232 optional) interface
•  Automatic environmental compensation
•  Supports NMTBA, VDI, ISO and ASME B5.54 standards


•  Linear calibration of CNC machine tools, CMM's, Leadscrews, and DRO's
•  Quality control maintenance
•  Ultra precision positioning


The MCV-500 Machine Calibration System features environmental compensation sensors. These devices automatically adjust the collected data for air temperature, barometric pressure, and thermal expansion of the axis being calibrated. With the "Automatic Data Collection", the operator programs the table into position, the system automatically senses the table movement and data is collected after a user defined interval.
