Cognex In-Sight L38 3D Vision System

The Cognex In-Sight L38 is a 3D profiling sensor based on laser technology, designed for precise Z-axis measurements and dimensional inspections in industrial applications.

It allows for the verification of shapes, heights, and the position of objects directly on the production line, making it suitable for applications where dimensional control and product consistency are essential.

Precise 3D measurements directly on the production line

In applications where dimensions matter, a 2D image is not enough. Differences in height, deformations, or variations in profile may go undetected, even if the product appears visually correct.

The Cognex In-Sight L38 solves this type of problem using 3D laser scanning. The system generates detailed surface profiles and enables the precise measurement of object height, shape, and position in real time.

Laser profiling for dimensional inspection

With high resolution along the Z-axis and up to 1,920 points per profile, the sensor can detect subtle variations in geometry. It is suitable for thickness measurements, level checks, shape inspection, or surface defect detection.

Suitable for various distances and applications

The series includes several models, each optimized for a specific measurement range and field of view. From compact applications involving short distances to measurements on larger objects, the system can be selected based on actual production requirements.

Stability in industrial environments

Its robust construction, IP65 protection, and stable operation under conditions of vibration and temperature fluctuations make it suitable for direct integration into production lines. The system can operate continuously without frequent adjustments.

Integration into automated processes

The In-Sight L38 can be used in conjunction with other vision systems or industrial equipment for comprehensive quality control. The data generated can be used for automated decision-making, sorting, or real-time process adjustments.

Who is it suitable for?

applications where precise measurement of height or profile is required
manufacturers that check thicknesses, levels, or 3D shapes
processes where defects cannot be detected using 2D vision
production lines that require constant dimensional control
integrations where 3D data is required for automation
