3D Line Confocal Sensors Hypersen

Presentation

The Hypersen 3D Line Confocal Sensor (HPS-LCF series) has broken through the limitations of traditional measurement methods and can provide precise optical measurements with higher accuracy and higher speed than traditional methods. It can perform high-precision 3D inspection with sub-micron accuracy for various complex objects such as transparent glass, film, lithium batteries, 3C electronic products and semiconductor components.

• Suitable for 3D inspection of transparent, mirror and highly reflective materials
• It can detect detailed raw data and generate various forms of 2D/3D graphs simultaneously
• Scan density is 2048 dots/line, Z-axis repeatability 0.3 µm
• Extremely fast scanning up to 35,000 lines/s
• Good SDK and software support in one place
• Measurements of several layers at the same time in multi-layer transparent materials
• It is used in industrial precision measurements and scientific research

Description of operation

The principle of the 3D line confocal sensor is to expand the scope of the focal halo of different colors of light by using special lenses to form a special increased chromatic aberration. Depending on the different distance between the target and the lens, light of a certain wavelength will be focused on the target. Then, by measuring the wavelength of the reflected beam, we can get the exact distance from the object to the lens.

The measurement results will not be affected by the intensity of the reflected light, meaning that the distance results remain the same regardless of how much light is reflected from the target. And since the intensity of the reflected light depends only on the reflectivity of the target, this sensor can make reliable measurements even if the target is a black material that absorbs light, such as black rubber, or transparent materials such as glass or liquid.
