In precision manufacturing production lines, thickness measurement has always been a critical factor in controlling product yield. Pain points associated with traditional contact-based measurement—such as the risk of scratching workpieces, insufficient accuracy in unidirectional measurements, and difficulties in adapting to special materials—have long plagued production and quality inspection processes in industries such as 3C and semiconductors. At this September’s Optics Expo, POMEAS introduced a high-precision, non-contact online thickness measurement solution specifically tailored to address these industry challenges.

Dual-Spectral Opposite-Beam Measurement, Accuracy Up to 1 μm

This solution employs dual-spectral opposite-beam measurement technology. Compared to traditional unidirectional measurement methods, it achieves significantly improved measurement accuracy—up to 1 μm—enabling the precise detection of micrometer-level thickness deviations. This ensures that every measurement result is highly reliable, fully meeting the stringent quality inspection requirements of high-end precision manufacturing.

Comprehensive Material Coverage—No Need to Frequently Switch Equipment

It overcomes the limitations of material compatibility, supporting thickness measurement for a wide range of materials—including metal, ceramic, mirror surfaces, and glass. There is no need to repeatedly switch inspection equipment for different workpieces, significantly reducing production line adaptation costs. A single device can meet the thickness measurement needs for most common workpieces in the workshop.

Adaptable to Demanding Conditions, Non-Destructive Real-Time Data Output

This solution has been specifically optimized for the complex conditions of industrial environments. Even in high-temperature, high-pressure production settings, the equipment maintains stable operation. It employs a non-contact, non-destructive measurement method throughout the process, causing no scratches or damage to the workpiece surface. Measurement data is output in real time as soon as the workpiece is positioned, fully aligning with the continuous production rhythm.

Interchangeable Probes for Seamless Integration into Production Lines

Additionally, it supports interchangeable probes of various specifications. Probes with different measurement ranges can be selected as needed, easily accommodating inspection requirements for products of various sizes. This also facilitates rapid integration into existing production lines without the need for major structural modifications.

High-Speed Sampling to Keep Pace with Production Line Rhythms

With its high-speed sampling capability of 8 kHz, this solution fully meets the cycle time requirements of high-speed in-line inspection and does not create a bottleneck in production line efficiency. Even in high-speed continuous production scenarios, it ensures that every workpiece undergoes precise inspection.

Implemented Across Multiple Industries, Covering Mainstream Precision Manufacturing Scenarios

It has already been implemented in thickness inspection scenarios across multiple industries, including 3C, glass panels, PCBs and semiconductors, photovoltaics, and medical devices, providing stable and reliable measurement support for quality inspection in precision manufacturing across various fields.
