Short-Wave Infrared (SWIR) Lenses
SWIR (Short-Wave Infrared, 0.9–1.7μm) imaging bridges the gap between visible light and thermal imaging. Unlike LWIR and MWIR which detect thermal radiation, SWIR cameras detect reflected near-infrared light, enabling unique imaging capabilities that are impossible with conventional thermal cameras.
Our SWIR lens series covers focal lengths from 8mm to 100mm with fast apertures for industrial, agricultural, and scientific applications. All lenses are anti-reflection coated for maximum transmission in the 900-1700nm atmospheric window.
Typical applications include semiconductor inspection, hyperspectral imaging, agricultural sorting, laser-based communications, and night vision with laser illumination.
SWIR Lens Key Features
High Sensitivity
Detect reflected near-infrared light with much higher sensitivity than thermal cameras for certain materials and scenes.
Day/Night Imaging
SWIR imaging works in both daylight and nighttime conditions, complementing traditional thermal imaging.
See Through Fog
SWIR light penetrates atmospheric haze and fog better than visible light for enhanced visibility.
Material Identification
Different materials exhibit unique spectral signatures in SWIR, enabling non-destructive testing and sorting applications.
