SPECIM FX50 Mid-Wave Infrared Hyperspectral Imaging Camera

Overview

The SPECIM FX50 Mid-Wave Infrared (MWIR) Hyperspectral Imaging Camera is an industrial-grade, push-broom scanning instrument engineered for real-time material identification and compositional analysis in automated production and sorting environments. Unlike visible or near-infrared (VNIR) systems, the FX50 operates in the 2.7–5.3 µm spectral band—where fundamental molecular vibrational absorption features of polymers, hydrocarbons, and organic contaminants exhibit strong, chemically distinct signatures. This enables unambiguous discrimination of black plastics (e.g., ABS, PP, PE, PC, PS, PVC, HIPS), which are optically opaque and spectrally indistinguishable under conventional RGB or NIR imaging. The camera employs binary optical elements to achieve diffraction-limited performance across its MWIR range, coupled with thermally stabilized optics to maintain spectral fidelity during continuous operation. Its 380 Hz frame rate supports high-speed conveyor-based inspection at line speeds exceeding 2 m/s—making it suitable for integration into recycling facilities, automotive component verification lines, and petrochemical QA workflows.

Key Features

• Push-broom architecture with 640 spatial pixels per line and continuous spectral sampling at 35 nm resolution
• Thermally regulated optical train ensuring <±0.1 nm spectral drift over 8-hour operational cycles
• GigE Vision-compliant interface (GenICam v3.1) enabling plug-and-play integration with standard industrial vision platforms
• Factory-applied spectral and radiometric calibration traceable to NIST-traceable blackbody sources
• Modular lens mount (M42 × 0.75) supporting interchangeable FOV options: 24°, 45°, and 60° TFOV
• Built-in non-uniformity correction (NUC), dark current compensation, and pixel defect mapping
• Ruggedized aluminum housing rated IP52 for dust resistance and operational stability in ambient temperatures from 5 °C to 40 °C

Sample Compatibility & Compliance

The FX50 is optimized for non-contact, standoff analysis of solid-phase materials under ambient lighting or controlled thermal emission conditions. It supports identification of black thermoplastics, elastomers, flame-retardant additives (e.g., brominated compounds), lignocellulosic substrates (wood, paperboard), and hydrocarbon-bearing minerals (e.g., quartz, feldspar). For metal surface inspection, the system leverages emissivity-corrected radiometric measurement to quantify surface temperatures from 0 °C to 1000 °C and detect sub-micron organic residues—including oils, greases, and polymer films—via their characteristic C–H and C=O absorption bands. While not a medical or pharmaceutical device, the FX50’s data output format (IEEE 1394/GenTL-compliant raw cubes) is compatible with GLP/GMP-aligned data archival pipelines when paired with validated third-party software. Its GigE Vision compliance ensures interoperability with machine vision systems certified to IEC 61131-3 and ISO/IEC 17025-accredited laboratories.

Software & Data Management

The FX50 ships with SPECIM’s proprietary INSIGHT software suite, providing real-time cube acquisition, spectral library generation (using ENVI-compatible .sli format), and multivariate classification (PCA, PLS-DA, SVM). An open-source SDK (C/C++, Python, MATLAB APIs) enables custom algorithm development and integration into SCADA, MES, or PLC-controlled decision logic. All spectral data is timestamped and embedded with metadata including exposure time, lens ID, calibration epoch, and environmental sensor readings (optional external temperature/humidity input). Raw hyperspectral cubes are stored in lossless HDF5 format with embedded checksums—ensuring auditability and long-term reproducibility per FDA 21 CFR Part 11 requirements when deployed with validated electronic signature modules.

Applications

• Automated black plastic sorting in post-consumer waste streams (WEEE, ELV, packaging)
• In-line quality assurance of painted or coated metal surfaces in automotive manufacturing
• Hydrocarbon detection and speciation in oil & gas pipeline monitoring and refinery feedstock screening
• Mineralogical mapping in mining exploration and ore grade control (e.g., quartz/feldspar ratio quantification)
• Wood species identification and moisture content estimation in pulp & paper grading
• Thermal anomaly detection and emissivity mapping on turbine blades, heat exchangers, and electrical contacts

FAQ

Is the FX50 suitable for outdoor deployment?
The FX50 is designed for indoor industrial environments. Outdoor use requires environmental enclosures with active cooling and solar radiation shielding to maintain thermal stability of the detector and optics.
Does the system require liquid nitrogen or Stirling cooling?
No—the FX50 uses a thermoelectrically cooled MCT (mercury cadmium telluride) detector operating at ~200 K, eliminating cryogen dependency and enabling continuous 24/7 operation.
Can spectral libraries be shared across multiple FX50 units?
Yes. All units undergo identical factory spectral calibration; spectral libraries generated on one FX50 are directly transferable to others without retraining, provided identical lens and illumination geometry are maintained.
What is the minimum detectable feature size?
Spatial resolution is determined by instantaneous field of view (IFOV), which depends on lens focal length and working distance. Typical IFOV ranges from 0.3 to 1.2 mrad—translating to ~0.6 mm to 2.4 mm at 2 m standoff distance with the 45° lens.
Is FDA or CE marking applicable?
The FX50 carries CE marking under the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. It is not a medical device and therefore not subject to FDA 510(k) or MDR certification.
