In today's rapidly changing science and technology, the innovation of inspection technology is crucial for industrial production and scientific research. Although traditional inspection methods have a long history, their cumbersome processes, limited accuracy and potential destructiveness limit their application in modern industry. In contrast, spectral sensors, especially POMEAS spectral confocal sensors, are gradually becoming a new trend in the future inspection field due to their high accuracy, non-contact measurement and wide applicability.

Limitations of traditional testing techniques

Conventional detection techniques, such as chemical titration and elimination methods, usually require complex sample pre-treatment and long detection times. For example, some chemical analysis methods may take hours or even days to obtain results, which not only reduces work efficiency, but also may introduce errors in the pretreatment process. In addition, some of the traditional testing methods can damage the samples, making them unusable for reuse, which is particularly unfortunate for samples that are precious, rare or difficult to obtain.

Spectral Confocal Sensors

1. High-precision measurement: POMEAS spectral confocal sensors utilize the principle of optical dispersion to determine the distance by searching for peaks in light intensity to achieve high-precision measurements. This technology is particularly suitable for scenarios where high accuracy is required and contact with the measured object is not possible, such as semiconductor chips, glass substrates, thin-film materials, and so on.

2. Non-contact measurement: Non-contact measurement avoids wear and tear or contamination due to contact, and is particularly suitable for situations where there are stringent requirements on the measurement surface. POMEAS spectral confocal sensors can measure surfaces made of plastics, glass, ceramics, metals, liquids, etc. with small spot size and high accuracy.

3. Wide range of applications: Spectral confocal sensors are not only capable of measuring thickness, width and flatness of objects, but can also be used for travel/height measurements, oscillation/vibration measurements, shaft eccentricity measurements and transparency thickness measurements. This makes POMEAS spectral confocal sensors widely used in semiconductor manufacturing, precision machining, aerospace, automotive manufacturing and many other industries.

4. Efficient Data Acquisition and Analysis: Spectral inspection can acquire a large amount of spectral information in a short period of time, realizing rapid inspection. For example, the near infrared spectral analyzer can complete the full spectral range scanning of the sample and detect a number of compositional indicators within 1 minute. POMEAS spectral confocal sensor combined with high-speed data acquisition and analysis technology, can capture the object's small oscillation or vibration, for the detection of dynamic performance is of great significance.

5. Non-destructive testing: Spectroscopic testing usually does not cause damage to the sample, and the sample can still maintain its original properties and morphology after testing. This is important for the identification of cultural relics, jewelry and other precious samples. POMEAS spectral confocal sensors do not cause any damage to the measured object during the measurement process, ensuring the accuracy of the measurement and the integrity of the sample.

While traditional inspection methods have met the inspection needs of the past to a certain extent, their cumbersome processes, limited accuracy and potential destructiveness have restricted their application in modern industry. In contrast, POMEAS spectral confocal sensors, with their high accuracy, non-contact measurement and wide applicability, are gradually becoming a new trend in future inspection.
