High-resolution SWIR image sensors that can perform imaging from visible light to short-wavelength infrared light
Offering precision in contaminant detection inspections and material sorting, as well as imaging that penetrates mist or smoke
SWIR image sensors are sensors that take in light from the short-wavelength infrared (SWIR) band. SWIR-band light can penetrate the silicon wafers of semiconductors to check positioning marks or internal defects; it can also penetrate opaque resin material to capture the content of a package. Because different substances have different light absorption characteristics, these sensors can be used for materials with a similar external appearance to perform material screening, identify contaminants, and detect otherwise imperceptible flaws and dents on produce. The use of SWIR imaging, which is not affected by fine airborne particles, means these sensors can also reduce the impact of mist, smoke, dust, and other substances to offer clear imaging of subjects that would not be perceptible to the human eye.
Sony’s SWIR image sensors use original SenSWIR™ technology to achieve both high resolution and compact sensor size. They are also compatible with imaging not only of SWIR-band light but also the visible light spectrum. In addition to digital output compatibility, they have functions like global shutter and trigger mode, making them suitable for industrial cameras.
