Overview
The Find-R-Scope® IRV84499C2X is a precision-engineered, standalone handheld near-infrared (NIR) imaging viewer designed for real-time visualization of radiation in the 350–1350 nm spectral range. Unlike thermal imaging systems that detect mid- to long-wave infrared (MWIR/LWIR) emissions via microbolometric sensors, this device operates on image intensifier tube (IIT) technology—specifically Gen II+ or equivalent vacuum phototube architecture—to convert incident NIR photons into visible-light phosphor output. The core optical path integrates a high-transmission f/1.8 50 mm objective lens with adjustable aperture control, enabling optimized signal-to-noise ratio (SNR) under low-flux conditions. Its spectral response is calibrated against standardized 400 µW 1350 nm LED sources at 2.4 m distance per ASTM E259–22 test methodology, ensuring traceable sensitivity across laboratory, field, and industrial QA/QC environments.
Key Features
- Optimized dual-lens configuration: Includes both standard 25 mm f/1.6 and enhanced 50 mm f/1.8 interchangeable lenses—delivering nominal 1× and 2× magnification respectively, with focus range extending from 1 m to infinity
- Integrated IRVLP830 visible-light cutoff filter (OD ≥ 5 below 700 nm), minimizing ambient visible contamination and maximizing NIR contrast
- Extended operational endurance: >98 hours continuous runtime on a single AA alkaline battery; total power system lifetime exceeds 2500 hours under typical intermittent use
- Lightweight ergonomic housing (590 g) with tripod mount (¼”-20 UNC thread) and ruggedized carry case featuring molded foam interior for shock and moisture protection
- Field-proven environmental resilience: Operational temperature range of –32 °C to +46 °C (–25 °F to +115 °F), compliant with MIL-STD-810G low-temperature storage and thermal shock protocols
- High-resolution phosphor screen output: Measured modulation transfer function (MTF) supports ≥40 line pairs per millimeter resolution at Nyquist frequency
Sample Compatibility & Compliance
The IRV84499C2X is validated for non-contact inspection of active and passive NIR-emitting components without sample preparation or coupling media. It complies with ISO/IEC 17025:2017 general requirements for calibration laboratories when used in conjunction with NIST-traceable reference sources. Applications involving forensic document analysis or medical device verification align with FDA 21 CFR Part 11 data integrity expectations when paired with optional video capture interfaces. All units ship with factory calibration documentation referencing ANSI Z97.1 impact resistance standards for optical housings and IEC 60825-1:2014 Class 1 laser safety certification for integrated LED test configurations.
Software & Data Management
While the base IRV84499C2X operates as an analog optical instrument, optional video interface modules (e.g., IRV-VMI series) enable digitization via USB 3.0 or HDMI outputs compatible with industry-standard acquisition platforms including LabVIEW™, MATLAB® Image Acquisition Toolbox, and open-source Python libraries (OpenCV, scikit-image). Timestamped frame capture supports GLP-compliant audit trails when configured with external time-synchronized recording hardware. Firmware updates—distributed exclusively through authorized distributors—are digitally signed and version-locked to prevent unauthorized modification, satisfying IEC 62304 software lifecycle requirements for Class B medical devices.
Applications
- Verification of NIR LED emission patterns and alignment in avionics lighting systems (per RTCA DO-160 Section 22)
- Non-destructive evaluation of fiber optic terminations and splice losses using 1310/1550 nm test sources
- Forensic examination of altered historical documents, ink differentiation, and underdrawing detection in fine art conservation
- In vivo small-animal NIR fluorescence imaging support during preclinical pharmacokinetic studies
- Validation of IR leakage from optically shielded enclosures in secure communications hardware
- Calibration and beam profiling of diode-pumped solid-state (DPSS) lasers operating at fundamental or harmonic wavelengths
- Low-light night vision augmentation in ecological field research without active illumination interference
FAQ
What is the spectral responsivity difference between the IRV84499C2X and the IRV84499C-52X models?
The IRV84499C2X covers 350–1350 nm with peak quantum efficiency at ~800 nm, while the IRV84499C-52X extends to 1550 nm using an InGaAs-based photocathode variant—optimized for telecom-band diagnostics but with reduced UV sensitivity below 500 nm.
Can the IRV84499C2X be used for quantitative radiometric measurements?
No—it is a qualitative imaging tool calibrated for relative intensity visualization, not absolute irradiance measurement. For quantitative NIR photometry, pairing with an NIST-calibrated spectroradiometer (e.g., Ocean Insight HDX series) is required.
Is the IRVLP830 filter permanently installed or user-removable?
The IRVLP830 is factory-installed and fixed within the optical train; removal voids calibration and invalidates warranty coverage.
Does the device require periodic recalibration?
Annual verification against a certified 1350 nm LED source is recommended per ISO/IEC 17025 Clause 7.7.1; full recalibration is performed only at authorized service centers using proprietary collimated beam test fixtures.
Are there electromagnetic compatibility (EMC) certifications for laboratory integration?
Yes—certified to EN 61326-1:2013 for EMC immunity and emissions in laboratory environments, with conducted/radiated emission limits meeting CISPR 11 Group 1 Class A requirements.
