In many industries, surface smoothness directly defines product quality, performance and aesthetics. Tiny bumps, dents, or rough patches can lead to premature wear, leakage, noise, coating failures, or customer complaints.
Intelgic’s Surface Smoothness Inspection System uses laser profile sensors and triangulation-based point laser sensors to measure surface roughness and automatically flag areas that are outside your acceptable thresholds. Wherever the surface smoothness crosses your defined limit, the system generates instant alerts so you can react before defective parts move further down the line.
Not every product or budget is suitable for full 3D profiling. Intelgic offers two complementary methods:
For critical components and smaller or medium-sized surfaces, Intelgic integrates laser profile sensors or 3D cameras to:
This approach gives rich, high-density data and is ideal when you need complete coverage and high accuracy on smaller areas.
For large products and wider surfaces, using 3D cameras or high-end laser profile sensors across the entire area can become very expensive and sometimes impractical.
To make surface smoothness inspection feasible for these applications, Intelgic uses triangulation point laser sensors:
This method is highly cost-effective for large components where full 3D coverage is not necessary but statistical or point-based surface quality control is essential.
Parts may be inspected in-line on a conveyor or stationary on a fixture.
The system is triggered automatically (sensor/encoder) or by an operator button.
Laser profile / 3D camera mode:
Triangulation point laser mode:
Engineers configure tolerance thresholds for smoothness/roughness (per product or recipe).
If the measured values exceed allowed tolerance, the system:
All inspection results are logged in Intelgic's Live Vision AI software (or your existing system via integration).
You get:
For wider sheets, panels, long profiles, slabs, rolls, and structural parts, full 3D inspection can be expensive (multiple cameras, large optics, complex mechanics) and overkill when only key functional areas need to be validated
Measuring surface smoothness at critical reference points
Using a simple mechanical motion (linear slides, rotary stages) to scan multiple points if required
Keeping the hardware cost and system complexity lower, while still giving you quantitative and repeatable surface quality data

Surface Smoothness & Roughness Inspection System
A surface smoothness inspection system uses laser sensors (laser profile/3D cameras or triangulation point lasers) to measure the roughness and micro-deviations on a surface. It ensures the surface meets your defined smoothness threshold and alerts you when it crosses the acceptable limits.
Intelgic uses two technologies:
Both methods give accurate, repeatable roughness values based on thresholds defined in the recipe.
Triangulation point lasers are ideal when:
This method provides cost-effective and reliable roughness data.
Yes. Using laser profile sensors or 3D cameras, Intelgic can perform full-area scans.
For large surfaces where full-area 3D scanning is impractical or too costly, we measure roughness at selected key points using triangulation lasers.
The system can detect:
Yes. Intelgic systems can be easily integrated with:
We support OPC, Modbus, TCP/IP, and REST API integrations.
Both options are supported.
Intelgic adapts the mechanical and sensor setup based on your process.
Yes. You can configure threshold values for each product model or recipe.
If the surface smoothness exceeds the allowed limit, the system immediately classifies the part as Fail/Reject and highlights the problem zone.
Absolutely. Intelgic’s Live Vision AI software generates:
Industries where surface quality is critical or aesthetic include:
Yes. Every Intelgic system is fully customizable including:
Accuracy depends on the selected sensor:
Intelgic recommends the appropriate sensor after reviewing your sample.
Yes. We encourage customers to send sample parts so our engineering team can:
