21. ONOSOKKI Laser Doppler Vibrometer - LV-1880

The LV-1800 non-contact type Laser Doppler Vibrometer uses newly designed interference optical system and has achieved improvement of detection sensitivity by 20 dB compared to the conventional models. The built-in positioning camera makes it easy to check the target by laser beam irradiation.

 ONOSOKKI  LV-1800 Laser Doppler Vibrometer

The LV-1800 can perform amplitude velocity measurements in a wide range of fields that are difficult with a contact type vibration sensor; small actuator using piezoelectric element, cell phones and digital camera with MEMS (Micro Electro Mechanical Systems), inverter an other devices in an EV/HEV. By using the LV-1800 with FFT Analyzer, it is possible to visualize not just vibration but the state of the vibration.

Features

- Integrated sensor and camera

Without degradation of the detection sensitivity, you can check targets and the parts irradiated by laser beams displaying on the Windows based PC.

-----

- Greatly increased detection ability 

   Newly designed interference optical system has achieved improved the detection sensitivity by 20 dB (ten times) compared to the conventional models. Restrictions of targets and detecting environment have been dramatically eased to facilitate sensor installation and setup.

------

- Detectable various targets with wide range up tp 4ranges

The LV-1800 can detect a wide range of amplitude from 0.05 µm/s* to 10 m/s from high velocity amplitudes of ultrasonic tools and piezoelectric devices to small amplitudes generated by thin film, MEMS, and ceramic capacitors. *: When the LV-0800 small velocity range board is mounted.

--------

-  Quick confirmation of the focal position and the detection status

The level indicator equipped on the sensor helps quick and reliable setup while checking the focal position or detection status at hand.

--------

-  Small and light-weight sensors with excellent ease of use 

Level indicator and error indicator are equipped on the sensor so that checking of detection status and setup become easy. As being designed to be separated from laser light source, the sensor is small and light-weight. Without any restrictions, laser beams can be irradiated in all directions.

-------

-  Easy storage and transporting

The main unit of the LV-1800 is 33% lighter compared to the conventional model. As the sensor and the cable can be stored in the main body, storage and transportation can be done easily and safely. Storage trunk (option) can store the magnetic stand, illumination unit as well as the main unit.

-------

-   Wide range of options provide utmost solutions

As the LV-1800 has wide variety of options, you can find suitable applications depending on requirements. For example, using the LV-1800 with an FFT Analyzer and exclusive software can visualize the behavior and characteristics of a target.
