Frequently Asked Questions about Laser Doppler Vibrometer

The micro-object observation system combines a video observation unit (LV-0180) and an objective lens (LV-0155) to monitor minute objects. It allows for measurement by irradiating the object, magnified by a small CCD camera and viewed on a TV monitor, with laser light from Laser Doppler Vibrometer focused to approximately 3 μm using the objective lens. The object can be viewed at approximately 280x magnification on a 15-inch monitor.

Furthermore, if the object is small, you can use a 20x objective lens (LV-0152) to view the object at an even higher magnification.
