Description
SpIRS for Advanced Infrared Analysis
The Spatially-Resolved Infrared Spectrometer SpIRS is engineered for high-precision hyperspectral applications. It combines fast-scanning interferometer technology with field imaging optics, enabling simultaneous acquisition on two 8×8 infrared detectors. With a spectral resolution as fine as 1 cm⁻¹, SpIRS provides highly detailed spectral information critical for material identification, target signature analysis, and environmental monitoring.
The instrument covers a wide infrared spectrum, from shortwave to longwave infrared (1.47–12.2 µm), making it suitable for both MWIR and LWIR applications. Its high sensitivity and low noise equivalent spectral radiance (NESR) ensure accurate detection of subtle signals, even in challenging or remote environments.
Field and Remote Operations
SpIRS is designed for portability and adaptability. With its compact form factor and multiple field-of-view options—wide, medium, and narrow—the spectrometer can be customized to specific mission requirements without compromising data quality. The system operates at up to 45 frames per second, enabling real-time monitoring and analysis in dynamic situations.
This versatility makes SpIRS ideal for defense, surveillance, and scientific research, where rapid, precise infrared measurements are essential. Its robust construction allows reliable operation in remote or vibration-prone environments, ensuring consistent performance across various field conditions.
Real-Time Hyperspectral Insights
With advanced interferometer modulation and integrated optics, SpIRS delivers actionable hyperspectral insights in real time. Its dual-detector setup enables simultaneous acquisition of multiple spectral bands, accelerating data collection and enhancing operational efficiency. Combined with its software capabilities, SpIRS allows users to conduct precise radiometric calibrations, perform spectral analysis, and monitor environmental or material signatures seamlessly.
By integrating high performance, flexibility, and field-readiness, the Spatially-Resolved Infrared Spectrometer SpIRS provides unmatched capability for professionals seeking accurate hyperspectral infrared measurements.
