Artray ARTCAM-991SWIR InGaAs SWIR Camera (400–1700 nm)

Overview

The Artray ARTCAM-991SWIR is a high-sensitivity, cost-optimized short-wave infrared (SWIR) imaging camera engineered for laboratory-grade optical characterization, spectral analysis, and industrial inspection applications. Built around a monolithic InGaAs focal plane array (FPA), it delivers photon-limited detection performance across a broad spectral band from 400 nm (visible edge) to 1700 nm — encompassing the critical NIR-II window (1000–1700 nm) where silicon-based sensors exhibit diminishing quantum efficiency. Unlike cooled MCT or InSb detectors, the ARTCAM-991SWIR operates at thermoelectrically stabilized temperatures (typically −5 °C to +15 °C), eliminating the need for liquid nitrogen or bulky Stirling coolers while maintaining stable dark current and low temporal noise. Its optical architecture supports standard C-mount and F-mount lens interfaces, enabling seamless integration into custom optical benches, hyperspectral line-scan systems, or OEM machine vision platforms.

Key Features

• Monolithic InGaAs sensor with extended spectral response (400–1700 nm), optimized for both visible-NIR transition and deep SWIR absorption features
• Thermoelectric (TEC) temperature stabilization for consistent dark current drift control (<0.5% RMS over 8 hours)
• High dynamic range (>65 dB) achieved via programmable gain and exposure time (10 µs to 1 s)
• Standard GigE Vision 2.0 interface compliant with GenICam protocol stack, enabling plug-and-play integration with HALCON, MATLAB Image Acquisition Toolbox, and LabVIEW IMAQdx
• Onboard FPGA-based preprocessing including non-uniformity correction (NUC), bad-pixel replacement, and real-time histogram equalization
• Ruggedized aluminum housing with IP52-rated environmental protection and ESD-safe grounding provisions for cleanroom-compatible deployment

Sample Compatibility & Compliance

The ARTCAM-991SWIR is compatible with standard optical components including achromatic doublets, aspheric lenses, and diffraction gratings designed for SWIR transmission. It supports transmissive and reflective measurement geometries in setups such as reflectance spectroscopy, laser beam profiling (e.g., 1064 nm, 1310 nm, 1550 nm sources), and semiconductor wafer inspection. The camera conforms to CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). While not certified for medical or aerospace use out-of-the-box, its hardware design aligns with key elements of ISO 13485 process controls and IEC 61000-6-3 emission limits. For regulated environments requiring audit trails or data integrity, optional firmware enables timestamped image metadata logging compliant with GLP documentation workflows.

Software & Data Management

Artray provides the ART-VIEW SDK — a cross-platform (Windows/Linux/macOS) C++/Python API supporting full register-level control, ROI selection, trigger synchronization (hardware/software), and streaming buffer management. All acquired frames embed EXIF-style metadata: acquisition timestamp (UTC-sync capable), sensor temperature, exposure duration, gain setting, and NUC calibration ID. Raw 16-bit TIFF export preserves full bit depth for post-acquisition radiometric analysis. When deployed in automated test systems, the camera supports metadata embedding per frame for traceability — a prerequisite for ISO/IEC 17025-accredited laboratories performing optical calibration services. No proprietary runtime or dongle licensing is required; SDK binaries are redistributable under a commercial OEM license.

Applications

• Non-destructive evaluation (NDE) of polymer composites and battery electrode coatings using SWIR reflectance contrast
• Real-time monitoring of laser-induced thermal processes (e.g., selective laser sintering, annealing) at 1070 nm and 1550 nm wavelengths
• Optical coherence tomography (OCT) reference arm imaging and dispersion compensation verification
• Sorting of agricultural produce based on water content and sugar concentration via 970 nm and 1450 nm absorption bands
• Characterization of quantum dot photoluminescence spectra beyond 1100 nm
• Integration into portable Raman spectrometers for Stokes-shifted signal capture in the 1200–1600 cm⁻¹ fingerprint region

FAQ

Is the ARTCAM-991SWIR suitable for quantitative radiometry?
Yes — when calibrated with NIST-traceable tungsten-halogen or blackbody sources, it supports relative radiometric accuracy within ±3% across its spectral range, provided proper flat-field correction and temperature-stabilized operation.
Can this camera be used in vacuum or high-humidity environments?
The standard housing is rated IP52; for vacuum or >85% RH operation, Artray offers optional hermetic sealing and fused-silica window variants upon request.
Does the camera support external triggering and synchronization with pulsed lasers?
Yes — it features TTL-compatible input/output trigger ports with sub-microsecond jitter and configurable delay modes for precise pump-probe or gated imaging sequences.
What is the warranty coverage and service support model?
Artray provides a 12-month limited warranty covering material and workmanship defects under normal laboratory use conditions; extended service contracts and on-site calibration support are available through authorized regional partners.
Are software updates and firmware patches provided free of charge?
Yes — all SDK updates, bug fixes, and minor firmware revisions are distributed at no cost via Artray’s secure customer portal for registered users.
