SWIR Image Sensor Technology

The demand for higher productivity is driving the growing interest in image capture in both the visible spectrum and SWIR wavelengths. For this reason, the market trend for SWIR sensors is promising and technical developments are progressing rapidly.
Do you already know SenSWIR?
With the Sonyā€™s SenSWIR technology, copper-to-copper connection enables a finer pixel pitch and smaller pixels. As a result, smaller high-resolution cameras can be developed, which can support higher inspection precision.

Discover several ways to benefit from Sonyā€™s first-class SWIR solutions
The demand for higher productivity is driving the growing interest in image capture in both the visible spectrum and SWIR wavelengths. For this reason, the market trend for SWIR sensors is promising and technical developments are progressing rapidly.
  • Clever solution: A wide-band and high-sensitivity SWIR image sensor technology implemented by the combination of compound semiconductor InGaAs photodiodes and Si readout circuits through Cu-Cu bonding.
  • Finer pixel pitch: Sonyā€™s SWIR sensors feature smallest pixels in the industry (as of May 2020).
  • Broad imaging: IMX990 and IMX991 sensors cover SWIR wavelengths up to 1.7 Ī¼m.
  • Imaging by the sensors also extends to wavelengths of visible light (which has proven difficult for conventional SWIR sensors to capture).

Explore the advantages in a variety of applications

Sorting of Products

Ideal for applications such as sorting fruits and vegetables, as light in the SWIR band enables detection of moisture content, which is difficult to determine under visible light.

Foreign Material Inspection

Properties of light absorption and reflection in SWIR imaging are applied to distinguish substances that would be difficult to differentiate under visible light alone.

Semiconductor Inspection

Light in the SWIR band passes through material made of silicon. This aspect of SWIR imaging is applied in semiconductor production and inspection.

Temperature Estimation

Around hot objects, light in the SWIR band shines quite brightly. Temperature can be estimated from differences in brightness among several wavelengths. This is used to estimate the temperature of welds or other hot areas.

Remote Observation

Light in the SWIR band has longer wavelengths than visible light. This makes the light less susceptible to scattering, thus apply SWIR imaging successfully in remote observation.
