Laser Profiler

Laser profilers are laser displacement sensors that collect height data across a laser line rather than a single point. This enables 2D/3D measurements such as height difference, width, or angle to be performed using a single sensor. In addition to height data, KEYENCE profile sensors also collect intensity data to provide a stable solution for inline measurement and inspection. The lineup includes a wide range of sensors to support a variety of applications and industries.

LJ-X8000 series - 2D/3D Laser Profiler

Perform 2D/3D measurement and inspection in line with the LJ-X8000 Series. Our most versatile lineup of laser profilers offers 3200 points/profile, making it easy to accurately measure any target shape or material from high-resolution images. The laser profile scanners are compatible with four different controller options, allowing users to select a setup that perfectly aligns system capability with any application requirements. The maximum laser linewidth reaches over 720mm (28"), and multiple can be paired together to scan even larger targets. Programming for these high-performance sensors is completed in three simple steps, making accurate in line 3D measurement accessible for users of any experience level.

LJ-V7000 series - High-speed 2D Laser Profiler

Measure the profile and shape of targets using the high-speed 2D laser profilers of the LJ-V7000 Series. By collecting height data across the laser line, this system makes 100% inspection possible for targets that alternative systems struggle with due to lack of contrast or glare. The sensor's blue laser and specialized CMOS offers a wide dynamic range, enabling measurement of targets with multiple surface types or colors - ranging from glass and metal to dark rubber. The high-speed sampling (up to 64kHz) enables parts to be measured during transportation, improving production efficiency. The LJ-V7000 Series sensors are also compatible with the controllers of the LJ-X8000 Series to perform 3D measurement and inspection.
