The AT500, a laser vibration meter, enables non-contact sensing by the optical heterodyne method. It integrates a sensor unit with a built-in laser tube and a demodulator, so it has a wide range of uses in manufacturing, investigations, research, and development.
Two models to meet various requirements
AT500-05
For case vibration, Motor vibration
AT500-20
For opticalpickup, Actuator
Ease of installation
The AT500 can be easily installed. A laser beam can be focused on the measuring spot simply by installing the AT500 horizontally. Necessary operations and displays are located on the front, which provides user-friendly operation.
Highly accurate vibration measurement for soft or light s
Non-contact vibration measurement achieves high accuracy without affecting the vibration of the .
Vibration measurement for small structures
As the diameter of a laser beam spot is very small (approx. 20μm when measured at close range), the vibration of very small structures can be measured.
Easy positioning of focus and reflected light
The dedicated, highly sensitive lens enables comparatively easy sensing, even for a material that dose not reflect a laser beam well. Moreover, the built-in auto-focus function automatically selects the optimum focal point.
Scalable functions
As the AT500 has a single range demodulating function, measurement is enabled simply by connecting it to the output terminal. Connecting to AT3700 or AT3600 demodulation unit, which can be purchased separately, enables a wider range of measurement
