Profile: Optodyne, Inc. designs, manufactures, and markets laser-based precision measurement equipment for machine tool calibration and compensation, metrology, nano meter positioning, vibration sensing, and a wide variety of other industrial applications. Our brands include Optodyne™, LDDM trade mark™, Laser Doppler Displacement Meter™, and Volumetric Calibration & Compensation™. We specialize in the laser Doppler displacement meter. It is ideal for many different applications requiring precise displacement measurements. Our MCV series is targeted for machine tool applications. In some combination, these packages measure linear displacement, pitch, yaw angles, straightness, surface flatness, parallelism, squareness and rotary displacement. Our VC series is designed for non-contact vibration applications in hard disk drive assembly, XY-stages, and CNC machine tools. The vibration sensor measures low or high frequency vibration, velocity and acceleration, settling time, dynamic response, power spectra density, and shock response spectra.
