Line Lasers
Turn a Laser Line into Precise Information.
A laser line can reveal what conventional 2D imaging cannot.
In 3D inspection and optical measurement, a precisely projected line makes height, shape and surface variations visible to the camera—enabling fast, non-contact inspection even on continuously moving materials.
Laser 2000 provides industrial line laser solutions designed for consistent optical performance, reliable operation and demanding machine vision environments.
What Does Your Application Need to See?
From Surface Defects to 3D Shape
Line lasers create a defined optical reference on the object. As the shape or height of the surface changes, the projected line changes with it—allowing the camera and vision system to extract dimensional information.
This enables applications that would otherwise require mechanical measurement or slower inspection methods.
Detect Surface Defects
Reveal cracks, holes, scratches and other variations on surfaces and continuously moving materials.
Measure Shape & Profile
Capture height, contour, warpage and 3D profile information without physical contact.
Guide Materials & Components
Use a clearly defined laser line as an optical reference for positioning and guidance.
Inspect at Production Speed
Measure continuously moving products, strip materials and conveyor-based processes without interrupting production.
The Quality of the Line Matters
A Line Is More Than Two Points
For reliable 3D measurement, the projected laser line needs to remain consistent across the complete field of view.
A homogeneous intensity distribution helps the camera detect the line reliably, while a constant line thickness supports accurate measurement across its entire length.
The optical design therefore needs to be matched to the laser source and application. Depending on the requirements, specialised optics and reduced-speckle technologies can significantly improve line quality and measurement performance.
Find the Right Line Laser
The right solution depends on more than line length or laser power.
Key considerations include:
Wavelength
Match the wavelength to the material, camera sensitivity and operating environment.
Optical Power
Provide sufficient signal and contrast for reliable detection under the actual measurement conditions.
Line Quality
Consider intensity homogeneity, line thickness and speckle according to the required measurement accuracy.
Optics
Select the optical configuration that creates the right line geometry and performance for the application.
Industrial Design
Consider robustness, reliability, size and electronic integration for continuous operation in industrial environments.
Laser Safety
Laser class and the required protective measures should be considered as part of the complete system.
Typical Applications
Surface & Defect Inspection
Detect cracks, holes, scratches and other defects on strip materials and surfaces.
3D Profile Measurement
Capture shape, height and dimensional information for inline measurement and inspection.
Warpage Measurement
Identify deformation and deviations from the required surface geometry.
Assembly Inspection
Verify component position, geometry and correct assembly.
Material Guidance
Guide strip materials and other continuously moving products without physical contact.
Weld-Seam Inspection
Measure and inspect weld geometry as part of automated production processes.
Tool Inspection
Evaluate tool shape and condition directly within machine-tool environments.
Built for Industrial Environments
Line lasers are used across very different production environments—from steel and metal processing to automotive, semiconductor, PCB, wood, textile, railway, traffic and logistics applications.
That makes reliable optical performance only part of the requirement. Mechanical robustness, industrial electronics and stable operation need to be considered together with wavelength, power and optics.
Laser 2000 helps evaluate these parameters as a complete combination rather than selecting the laser module in isolation.
