LV-9002 / LV-9300A / LV-0121A

The LV-9002/LV-9300A is a high-precision, high-speed response non-contact length measurement system that uses He-Ne laser light to measure linear displacement.
 
With a simple configuration that includes an interferometer, high-speed response of 5 m/s, and high-speed sampling of up to 1 MHz, it can perform high-precision positioning measurement and analysis for OA equipment such as printers, scanners, and copiers, as well as for machines with precision and high-speed positioning mechanisms like machine tools and moving stages.
 
By using a micro corner cube weighing less than 0.2 g, the movement of small ultrasonic linear actuators can achieve higher precision analysis and evaluation than ever before, minimizing errors due to mass load.
 
Additionally, by using the LV-0930 displacement analysis software, it is possible to analyze the dynamic behavior that occurs when the measurement target moves and stops at a maximum sampling rate of 1 MHz. In addition to the target's displacement (m), speed (m/s), and acceleration (m/s2), measurements of overshoot and undershoot can be taken, and by using two sensors, pitching and yawing analysis can be performed in differential and differential measurements. It is also easy to display graphs showing how close the constant speed control is to the target speed within a certain percentage ±% graph.
 
The laser length measurement system consists of the following three units:
・LV-9002 Sensor
・LV-9300A Laser Length Meter
・LV-0121A Digital Displacement Meter
By combining these, it can be configured as a 1ch length meter or as a 2ch length meter for pitching & yawing or differential measurement systems.

Features

  • Simple structure of an integrated interferometer

  • Maximum 5 m/s, 1 MHz sampling, high-speed response.

  • The super lightweight corner cube (below 0.2 g / 2.0 g) reduces the impact of mass load.

  • The displacement output comes standard with both digital and analog options, allowing for simultaneous observation with other signals.

  • Combining with the LV-0930 displacement analysis software, simultaneous conversion from displacement to velocity to acceleration is also easy.

Measurement of dynamic characteristics of high-speed chip mounters and dispenser heads.

The minimum corner cube used with the laser measuring devices LV-9002/LV-9300A has a very small mass of less than 0.2 g. This allows for minimizing the forces generated by the acceleration of the corner cube when the measurement target operates or stops. It enables high-precision evaluation of high-speed equipment such as chip mounters and dispenser heads.

Dynamic characteristic analysis in digital and analog.

The LV-9002/LV-9300A/LV-0121A is equipped with analog displacement output at a 1 MHz sampling rate, in addition to digital data analysis using the LV-0930 displacement analysis software. It allows for synchronized evaluation with other detectors such as measurement microphones, accelerometers, and current probes that are attached to the measurement target to assess displacement values (m).

  • Dynamic characteristic analysis in digital and analog.

Measurement of Pitching and Yawing

By using two laser length measurement sensors, it is possible to evaluate the slight differences in angles, displacements, speed, and acceleration that occur during the operation of the stage, such as pitching and yawing. Additionally, differential evaluation against arbitrary parts is also possible.

Options

LV-0930 Displacement Analysis Software

By using the LV-0930 displacement analysis software, you can analyze the dynamic behavior that occurs when the measurement target moves to a stop at a maximum sampling rate of 1 MHz. In addition to the target's displacement (m), velocity (m/s), and acceleration (m/s²), you can measure overshoot and undershoot, and by using two sensors, you can analyze pitching and yawing in differential and differential terms.
You can also easily display graphs showing within what percentage of the target speed the constant speed control is operating, such as a ±% graph.
