ThermoConcept Infrared Teaching System

Overview

The ThermoConcept Infrared Teaching System is a pedagogically engineered educational platform designed to introduce students and educators to the foundational principles and practical applications of infrared thermography. Built around the FLIR Thermovision A320 uncooled microbolometer infrared camera (320 × 240 pixel resolution, spectral response 7.5–13 µm), the system enables real-time thermal visualization and quantitative surface temperature mapping under controlled experimental conditions. Its core measurement principle relies on detecting mid-wave infrared radiation emitted by objects in accordance with Planck’s law of blackbody radiation, while accounting for emissivity, reflectivity, and atmospheric transmission effects. The system is purpose-built for laboratory-based physics, materials science, and engineering curricula — from upper-secondary (lycée) to undergraduate and graduate university programs — supporting hands-on exploration of heat transfer mechanisms, optical properties in the IR band, and non-destructive evaluation methodologies.

Key Features

• Integrated FLIR Thermovision A320 infrared imaging module with calibrated radiometric output and real-time thermal video streaming at up to 50 Hz frame rate
• Dual xenon illumination units for controlled active thermography experiments (e.g., pulsed heating, lock-in thermography fundamentals)
• Modular test bench with adjustable sample stage, thermal shielding enclosure, and standardized mounting interfaces for reproducible positioning
• Comprehensive portable kit including reference samples (metals, polymers, composites, ceramics), emissivity calibration tiles, thermal gradient plates, and optical filters
• Dual-license software suite: student edition (guided experiment workflows, simplified interface, pre-loaded scripts) and instructor edition (full parameter control, script editor, data export in CSV/HDF5, batch analysis tools)
• Native support for ASTM E1934-19 (Standard Guide for Examining Electrical and Mechanical Equipment with Infrared Thermography) and ISO 18434-1 (Condition monitoring — Thermography — Part 1: General procedures)

Sample Compatibility & Compliance

The system accommodates planar and low-curvature specimens up to 200 mm × 200 mm × 50 mm (L × W × H), with surface emissivity ranging from 0.2 to 0.95. Sample holders are compatible with standard ISO 13320-compliant mounting fixtures. All hardware components meet CE marking requirements for electromagnetic compatibility (EN 61326-1) and safety (EN 61010-1). Software complies with academic data integrity standards, providing full audit trail logging for lab report generation and GLP-aligned documentation. While not FDA-regulated, the system architecture supports 21 CFR Part 11-compliant user authentication and electronic signature configurations when deployed in research environments requiring regulatory traceability.

Software & Data Management

The proprietary ThermoConcept LabSuite software is built on a Python-based framework with Qt GUI and OpenCV-accelerated image processing pipelines. It includes embedded educational modules aligned with European Physics Curriculum frameworks (IB, Baccalauréat, Bologna Process). Core capabilities include emissivity correction wizard, time-series thermal profile extraction, isotherm overlay, dynamic delta-T analysis, and FFT-based thermal wave decomposition for subsurface defect localization. Data exports conform to FAIR principles (Findable, Accessible, Interoperable, Reusable): metadata-rich TIFF/RAW files include EXIF tags for camera settings, ambient conditions, and operator ID. Instructor version enables custom scripting via Jupyter-compatible kernel integration, allowing extension into research-grade applications such as thermal diffusivity estimation (via flash method approximation) or transient conduction modeling validation.

Applications

• Teaching fundamental IR phenomena: spectral emissivity variation, Kirchhoff’s law of thermal radiation, Stefan–Boltzmann law, Wien’s displacement law, and atmospheric absorption windows
• Qualitative thermal property assessment: comparative analysis of thermal effusivity (‘thermal inertia’) across material classes using transient heating protocols
• Active thermography demonstrations: detection of subsurface discontinuities (delaminations, voids, disbonds) in layered structures through thermal wave propagation anomalies
• Electro-thermal coupling studies: visualization of Joule heating in circuit traces, contact resistance hotspots, and thermal management efficacy in prototype PCBs
• Environmental physics labs: urban heat island simulation, building envelope thermal bridging analysis, and solar absorptance/emissivity trade-off characterization

FAQ

Is the Thermovision A320 camera included with factory calibration certificates?
Yes — each unit ships with NIST-traceable calibration documentation valid for 12 months from date of shipment.
Can the system be used for quantitative thermal diffusivity measurements?
While primarily designed for qualitative and semi-quantitative instruction, the instructor software supports basic flash-method-derived diffusivity estimation using time-to-peak analysis on thin-sheet samples.
Does the software support third-party hardware integration (e.g., DAQ systems, environmental chambers)?
LabSuite provides TCP/IP and USB CDC serial APIs; MATLAB and Python SDKs are available under academic licensing for custom instrument synchronization.
What training resources accompany the system?
A complete pedagogical package includes 12 structured lab manuals (with learning objectives, safety notes, and assessment rubrics), instructor slides, raw dataset archives, and video walkthroughs — all provided in English and French.
Is remote teaching support enabled?
Yes — the software includes built-in screen-sharing mode optimized for Zoom/Teams, with synchronized thermal video streaming and real-time annotation tools for virtual classroom delivery.
