Yes, SWIR cameras leverage differences in reflectance and transmittance of various materials in the short-wave infrared range to identify objects or components that are difficult to distinguish under visible light. This capability is widely used in security inspection, industrial sorting, non-destructive testing, and more.
Short-wave infrared light can penetrate and absorb substances with different interactions from visible light, and obtain clear images when penetrating obstacles such as fog, smoke and glass; it can easily distinguish visually similar colors under visible light, improving recognition accuracy; even in low-light environments, it can output high-quality imaging, adapting to more complex application scenarios.
To meet the diverse application demands of short-wave infrared (SWIR) imaging, Attostek offer a series of high-performance SWIR lenses. This lineup covers focal lengths from 6mm to 100mm and features a wide aperture range of F1.4 to F2.0 as standard, ensuring high signal-to-noise ratio and superior image quality even in low-light conditions. Users can flexibly select different models based on field of view, working distance, and resolution requirements, providing high sensitivity and versatile scene adaptability for SWIR cameras in applications such as security surveillance, industrial inspection, and scientific research.
