Three-dimensional microscope unit
LV-0383

The 3D microscope unit LV-0383 is a 3D microscope unit for the Laser Doppler Vibrometer. It can non-contact detect the vibrations of small objects occurring in three axial directions using three Laser Doppler Vibrometers and a microscope device.
With coaxial reflected illumination and two digital video cameras with different magnifications*, quick and accurate positioning and still image recording are possible.
It enables the evaluation of the three-dimensional behavior of MEMS (Micro Electro Mechanical Systems), small structures, low mass targets, and ultrasonic-driven target vibrations that are difficult to detect by contact methods.
*When the built-in camera for positioning LV-0181 is mounted on the Laser Doppler Vibrometer LV-1800.

Features

  • It is possible to detect non-contact vibrations in three axes from 0.3 Hz to 100 kHz ※1.

  •  You can position the target to be detected and the irradiated laser light while observing them simultaneously at two magnifications (fields of view) ※2. 

  • It is possible to detect small objects with a laser spot diameter of 4.5 µm.

  •  Laser Doppler Vibrometer LV-1800, LV-1710 ※3 / LV-1720 ※3 / LV-1720A ※3 are supported.
