NEXT-GENERATION 4K LASER SCANNERS WITH BREAKTHROUGH GREEN LASER TECHNOLOGY
icro-Epsilon has expanded its
scanCONTROL LLT portfolio with a new generation of ultra- compact 4K laser line profile sensors, delivering
a step-change in 3D measurement performance. At the heart of the new LLT8x00 series is innovative Green Laser Technology, a major advancement over conventional red and blue laser systems. Combined with an ultra-high resolution 4K sensor matrix, integrated 3D processing directly in the sensor head and Industrial Ethernet connectivity, the new scanners set a new benchmark for precision, stability and ease of integration.
4K RESOLUTION AND MICRON-LEVEL PRECISION
The new 4K sensor matrix redefines what is possible in inline measurement with up to 4,224 points per profile. Line point resolution is down to 6 µm and a z-axis linearity of < 0.8 µm (0.005 per cent) enables even the finest structures to be captured with outstanding clarity, while maintaining high-speed performance
across varying surfaces and lighting conditions. With a 10 kHz profile frequency and 25 million points per second, the scanCONTROL LLT8500 offers the highest measuring rate in its class.
A CLEAR LEAP FORWARD: GREEN LASER TECHNOLOGY
The introduction of 520 nm green laser technology represents a significant performance leap over traditional red and blue laser solutions. Operating close to the peak quantum efficiency of the receiver, the green laser delivers:
Exceptionally stable signals with minimal noise
Superior performance on challenging surfaces such as shiny metals, PCBs, and organic/translucent materials
Shorter exposure times for faster measurement cycles
Increased repeatability and process reliability
The result is consistently accurate measurement in applications where conventional laser technologies struggle, dramatically expanding the range of viable inspection tasks.
INTEGRATED 3D INTELLIGENCE AND NO EXTERNAL CONTROLLER REQUIRED For the first time, full 3D data processing is performed directly inside the sensor head. This eliminates the need for external processing units or PCs when in production, reducing system complexity, cost, cabling and integration time. Processed measurement values can be transmitted directly to PLCs via Industrial Ethernet, or users can output calibrated 3D point clouds for further analysis. This makes the LLT8x00 series ideal for machine building and automation tasks.
FLEXIBLE DATA OUTPUT FOR ANY APPLICATION
The LLT8x00 series can operate as a standalone SMART 3D sensor with onboard evaluation or as a high-speed 3D data source for external processing. For onboard SMART 3D evaluation, Micro- Epsilon’s 3DInspect software tool allows users to configure measurement programs, analyse point clouds, and extract features directly within the sensor environment. Alternatively, calibrated point cloud data can be exported for processing using the customer’s own image processing software or existing vision processing tools.
PRECISE REAL-TIME 3D SCANS FOR MAXIMUM PROCESS RELIABILITY 3D laser scanners from Micro-Epsilon capture surfaces, geometries and height differences with extremely high precision, even during rapid movements. As a result, they outperform conventional image processing technologies and ensure maximum process reliability in challenging industrial applications. Here are some typical applications:
