Frequently Asked Questions

Learn more about SWIR short-wave infrared camera technology

Electromagnetic spectrum diagram: UV 200–380 nm, Visible light 380–750 nm, Near infrared 750–1100 nm, Short-wave infrared 1100–2500 nm, Long-wave infrared 8000–14000 nm

A SWIR camera is a professional imaging device that operates in the short-wave infrared spectrum (approximately 400–1700 nanometers). It can achieve imaging effects that go beyond visible light but differ from thermal imaging cameras (LWIR), making it widely applicable in scenarios requiring high standards for materials, structures, and details.

SWIR cameras have wide applications including industrial inspection, machine vision, material sorting, food testing, scientific research, medical diagnostics, security monitoring, process control, and transportation. They are particularly outstanding in material analysis, moisture detection, penetration through fog/smoke/dust, and night surveillance.

Yes! SWIR cameras can see through certain materials that are opaque to visible light, such as certain plastics and silicon wafers. This capability is extremely valuable for semiconductor inspection, material testing, and other industries.

SWIR cameras primarily capture reflected or emitted light in the short-wave infrared range, unlike thermal imaging cameras (LWIR) which rely on thermal radiation from objects. SWIR cameras have lower thermal sensitivity than thermal imaging cameras and are better suited for structural analysis and material identification rather than direct temperature detection.

Theoretically, yes. SWIR cameras can identify objects or components that cannot be distinguished in visible light through differences in reflection and transmission of materials under short-wave infrared light. They are widely used in security screening, industrial sorting, and inspection applications.

Deep Understanding of SWIR Cameras

Short-Wave Infrared (SWIR) cameras and their core sensors are important components of advanced imaging systems. SWIR technology covers the 900–1700 nanometer wavelength band and has excellent penetration capabilities in harsh environments, such as penetrating fog, smoke, and dust to achieve clear imaging under extreme conditions.

SWIR cameras primarily rely on short-wave infrared light reflection, similar to the visible light band, complementing the application range that thermal imaging cameras (LWIR) cannot cover, providing more complete imaging solutions. They are compact and flexibly integrated, making them easy to apply in various industrial and commercial systems.

The high resolution and high sensitivity of SWIR cameras can meet precision detection and high-requirement applications, capable of detecting minute changes and anomalies in samples, making them very suitable for quality control and defect detection. Some models support cooling, further ensuring imaging quality in high-temperature or high-noise environments.

To reduce system costs and improve integration efficiency, modern SWIR cameras commonly adopt standard optical interfaces and compact designs to accommodate broader application requirements. With the continuous development of imaging markets and technology, SWIR cameras have become one of the key technologies for high-end imaging and sensing in multiple industries due to their unique advantages.
