Principle Introduction

The principle of 3D line confocal sensor is to extend the focus halo range of different colors of light by using special lenses to form a special magnified chromatic aberration. According to the different distance between the target and the lens, the light with a certain wavelength will be focused on the target. Then, by measuring the wavelength of the reflected ray, the precise distance from the object to the lens can be obtained.

The measurement results will not be affected by the intensity of the reflected lights, which means that the distance results stay the same no matter how much light is reflected from the target. And because the intensity of the reflected light only depends on the reflectivity of the target, this sensor can conduct reliable measurement even if the target is a strong light-absorbing material, such as black rubber, or transparent materials, such as glass or liquid.

Advantages

The advantages of 3D Line Confocal Sensor

1. Excellent Adaptability to Various Materials

High-precision measurement can be achieved for almost all materials, including highly reflective ones.

2. Multilayered Materials Inspection

By means of its unique line chromatic confocal scanning technology, Hypersen 3D line confocal sensors can construct 2D and 3D data of multiple transparent layers by scanning the display surface only once.
Regardless of the glass thickness, it can provide excellent scanning performance on the glass surface and curved edges (=20.5°), and perform inline defect detection accurately, such as chips and cracks.

3. Line Confocal Scannig in One Step.

This sensor adopts the unique line confocal scanning technology. Various forms of appearance diagrams and detailed raw data can be obtained by only one scan on the target surface. For example : 3D point cloud, 2D contour image, HD depth image, HD grayscale image, Dimensions/Surface roughness, Topography/Flatness, Defects/Thickness, Tomography/Step height, Gap and flush measurement

4. Micron-level Inspection with High Speed

Scanning at 2,048 points/line with the minimum point interval of 2.9um.
The Z-axis repeatability is up to 0,1 pm, which provides you with more accurate measurement results.
Maximum scanning speed: 35,000 lines/sec.
