1. Infrared Imaging Takes a Larger Role in Industrial Automation
Raytron OEM showcased its latest short-wave infrared (SWIR) cameras and long-wave infrared (LWIR) thermal imaging modules at VISION 2026, held at Messe Stuttgart, Germany, from October 6 to 8, 2026. The exhibition demonstrated how infrared technology can expand machine vision capabilities beyond conventional visible-light inspection.
For manufacturers, the value of infrared imaging lies in its ability to capture information that standard cameras may miss. Depending on the wavelength and application, these systems can help identify material differences, detect moisture variations, inspect production processes, and monitor temperature without physical contact.
In my view, infrared imaging is becoming more relevant as industrial inspection moves toward higher process speeds and more demanding quality requirements. The key is not simply to collect more image data, but to extract useful information that supports timely and accurate production decisions.
2. High-Speed SWIR Cameras Support Advanced Machine Vision
Raytron OEM presented several SWIR camera models designed for different industrial imaging requirements.
The NS-615AS-10GE features a resolution of 640 × 512 pixels, a 10GigE interface, and full-frame operation at up to 825 frames per second. These specifications make it a candidate for high-speed inspection tasks, including semiconductor inspection and material sorting, where acquisition speed and data throughput can influence overall system performance.
The company also exhibited the NS-615A-GE area-scan SWIR camera and the NS-101L2 line-scan SWIR camera. These models offer different image acquisition formats and interface options for integration into automated vision systems.
Live demonstrations illustrated the practical potential of SWIR imaging. Raytron OEM showed how infrared images could distinguish sugar from salt and compare dry and wet biscuit samples.
These examples highlight an important engineering consideration: some inspection problems cannot be solved efficiently by visible-light cameras alone. However, successful implementation still depends on selecting the appropriate wavelength, optics, illumination arrangement, and image-processing method for the target material.
3. Thermal Imaging Modules Simplify OEM Integration
Raytron OEM also presented thermal imaging components for manufacturers developing their own inspection and monitoring equipment.
The SE5 1280 thermal imaging module provides a resolution of 1280 × 1024 pixels, a compact form factor, and multiple digital interfaces. These features give OEM developers options for incorporating thermal imaging into products without designing the entire imaging subsystem from the ground up.
The WN2T Series temperature measurement modules combine non-contact temperature measurement with compact dimensions and low power consumption. Such characteristics can benefit applications where equipment space, electrical power, and integration flexibility are important design constraints.
From an automation engineering perspective, resolution alone does not determine whether a thermal module is suitable for a particular task. Developers should also evaluate temperature measurement accuracy, thermal sensitivity, frame rate, field of view, calibration requirements, and operating conditions. Interface compatibility and software support also influence the effort required to integrate the module into an existing control architecture.
4. Thermal Vision Addresses Battery Safety and Process Quality
On October 8, Fushuai Liu, Head of Europe & Americas at Raytron, delivered a presentation titled "How Infrared Perception Is Shaping Industrial Machine Vision in Europe" during Industrial VISION Days.
Drawing on the Raytron EV Lithium-ion Battery Thermal Safety White Paper, the presentation examined battery safety, manufacturing quality, and traceability in the context of the EU Battery Regulation.
Raytron outlined a three-layer Thermal Vision framework consisting of thermal imaging hardware, data analysis and management, and integration with existing plant control and safety systems.
This approach reflects a broader shift in industrial monitoring. Thermal imaging becomes more useful when temperature data is connected to production records, alarm logic, and established operating procedures. Instead of treating each thermal image as an isolated observation, manufacturers can use time-series data to identify abnormal temperature patterns and document process conditions.
However, thermal monitoring should complement rather than replace established battery safety measures. Its effectiveness depends on suitable sensor placement, validated alarm thresholds, adequate response procedures, and integration with the plant's wider safety architecture.
5. Online Thermal Cameras Enable Continuous Process Monitoring
Raytron OEM highlighted several industrial thermal imaging applications, including the TN460U ultra-high-temperature thermal camera for battery safety testing and the TN430/TN460 online thermal cameras for monitoring die-casting mold temperatures.
In die-casting operations, mold temperature can influence process consistency, cycle conditions, and product quality. Continuous thermal monitoring can help operators identify temperature variations and investigate potential process deviations before they result in larger production problems.
Battery manufacturing presents a different set of challenges. Temperature monitoring can support testing, production, and storage operations by providing additional information about abnormal thermal conditions.
The practical advantage comes from turning measurements into actionable information. For example, a monitoring system can record temperature trends, generate alerts when validated thresholds are exceeded, and preserve historical data for quality investigations.
Nevertheless, engineers must distinguish between detecting a thermal anomaly and identifying its root cause. Temperature changes can have multiple explanations, so manufacturers should correlate thermal data with process parameters and other relevant measurements before making corrective decisions.
6. Connecting Infrared Sensors with Existing Control Systems
Raytron's three-layer Thermal Vision framework also raises an important integration question: how should infrared imaging fit into an established industrial control environment?
In a typical implementation, infrared cameras or modules provide image or temperature data. Processing software then evaluates the measurements, while a supervisory or plant-level system presents trends, records events, and communicates alarms to operators.
Depending on the equipment and application, integration may involve PLCs, SCADA platforms, manufacturing execution systems, or dedicated quality-monitoring software. The appropriate architecture depends on data rates, response requirements, communications interfaces, and the consequences of a missed detection.
Engineers should define these requirements before selecting hardware. They should also assess network capacity, time synchronization, data retention, cybersecurity, and maintenance access.
For applications involving personnel protection or critical process hazards, designers must establish appropriate safety functions independently and verify that the complete system meets the applicable requirements. A thermal camera should not automatically be treated as a safety-rated device.
7. Engineering Perspective: Data Quality Matters More Than Image Volume
Raytron OEM's VISION 2026 showcase illustrates how infrared imaging can address inspection tasks that conventional machine vision may struggle to handle. SWIR cameras offer opportunities for material differentiation, while LWIR thermal imaging supports temperature monitoring and process analysis.
However, adding an infrared camera does not automatically improve production performance. The real engineering challenge is to establish a measurable connection between sensor output and a specific manufacturing requirement.
Before deployment, engineers should identify the defect or process condition they need to detect, verify that the selected spectral band can reveal it, and test the system under representative production conditions. They should also quantify detection performance, false alarms, response time, and maintenance requirements.
This validation step is particularly important when manufacturers move from a successful exhibition demonstration to continuous operation on a production line. Laboratory conditions and real factories differ in ambient temperature, vibration, contamination, material variation, and operating speed.
Ultimately, the most useful infrared vision system is not necessarily the one that produces the most data. It is the one that consistently provides relevant measurements, integrates with the production workflow, and helps operators make better-informed decisions.
8. Outlook for Infrared Imaging in Industrial Automation
Through product demonstrations and technical discussions at VISION 2026, Raytron OEM presented a range of infrared imaging technologies for industrial inspection, OEM product development, and continuous temperature monitoring.
Its SWIR cameras address high-speed imaging and material differentiation, while its thermal imaging modules and online cameras target temperature measurement and industrial process observation.
As manufacturers pursue more automated inspection and improved traceability, infrared technology may become an increasingly useful complement to conventional machine vision. Its long-term value, however, will depend on application-specific validation, practical system integration, and the ability to convert sensor data into meaningful operational outcomes.
