Measurement frequency: Wide range from 0.3 Hz to 3 MHz
Detection sensitivity has been increased 10 times (+20dB) compared to conventional models.
The main unit weight has been reduced by 33% compared to the previous model.
Miniaturizing sensors and improving handling
With the built-in TV camera (optional), you can clearly see and position the target object.
The LV-1800 Laser Doppler Vibrometer is a vibration sensor that uses the Doppler shift of laser light to detect the amplitude and velocity of vibrations without load or contact. It enables measurement of high-speed, high-frequency, transparent, thin-film, and extremely small objects, as well as non-contact long-distance vibration detection, which are difficult to measure with contact-type vibration sensors. Compared to the conventional LV-1700 model, the LV-1800 boasts a significant 10-fold (+20dB) increase in detection sensitivity and achieves a measurement frequency range of 0.3 Hz to 3 MHz. Furthermore, by installing the optional built-in TV camera LV-0181, clear image positioning is possible, and it can be used without illumination. These features make it suitable for vibration detection of small ultrasonic actuators using piezoelectric elements, vibration evaluation of MEMS (Micro Electro Mechanical Systems) built into mobile phones, smartphones, and digital cameras, and even for detecting the behavior of biological parts and insects.
