What pain points can the NewScan Intelligent Fouling Detection System for Welding Lenses solve?
During the welding, cleaning, or marking process of laser equipment, a large amount of fumes and spatter are generated. These substances tend to contaminate optical lenses, leading to reduced equipment power, unstable processing quality, and consequently, significant economic losses. The traditional method of relying on manual periodic shutdowns for inspection is not only inefficient but also makes it difficult to unify judgment standards, resulting in strong subjectivity and low reliability.

Principle of Intelligent Lens Fouling Detection
The detection of lens fouling is implemented based on the principle of the thermoelectric effect. When there are contaminants on the lens surface, the thermal radiation characteristics of the lens change, leading to abnormal distribution of the local temperature field. After this temperature change is received by a thermosensitive sensor, a corresponding electrical signal is generated due to the thermoelectric effect. This electrical signal then undergoes a series of processes—including amplification, filtering, comparison, and counting—via a signal processing circuit. This enables accurate determination of the lens’s fouling status, and ultimately achieves automatic detection and control of the inspected object.
What functions does the intelligent lens contamination detection system have?


1.Precise Detection and Localization:
Based on high-sensitivity sensing technology, it automatically identifies lens contamination, accurately locates the contaminated area, and simultaneously determines the contamination level. This effectively eliminates subjective errors caused by human vision, ensuring fast and reliable detection results.
2.Intelligent Early Warning and Strategic Response:
It compares contamination thresholds in real time, formulates differentiated alarm strategies based on contamination levels, promptly prompts cleaning or replacement, and provides early warnings for welding quality risks to ensure the continuous and stable operation of the processing process.
3.Rapid Maintenance and Response:
It supports a design for quick cleaning and replacement, significantly reducing downtime. Combined with the contaminated location indication function, it makes maintenance operations more targeted and improves overall operational efficiency.
4.Long-Term Protection and Service Life Enhancement:
Specialized protective lenses effectively block welding spatter and dust, reducing the wear of optical components. Combined with contamination level monitoring and early warning, they further extend the service life of core components.
