ONO SOKKI - Laser Doppler Vibrometer LV-1800 -
[Contact Us]
The LV-1800 Laser Doppler Vibrometer features a new optical system with 20 dB increased sensitivity, enabling precise, non-contact measurements. Its built-in camera aids in target visualization. Lightweight and versatile, it covers a wide range from ultrasonic tools to MEMS devices, easily integrating with an FFT Analyzer.
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 to 4 ranges
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.
