As demands in industrial inspection, spectral imaging, and semiconductor testing become increasingly stringent, traditional visible-light sensors can no longer meet the detection requirements of modern applications in the short-wave infrared (SWIR) band. As a leading supplier of electronic components, Shenzhen Mingjiada Electronics Co., Ltd. is now offering Sony’s next-generation SWIR image sensors—the IMX990-AABA-C and IMX990-AABJ-C—in bulk to its customers.
Leveraging Sony’s proprietary SenSWIR technology, these two sensors have broken through the size limitations of traditional InGaAs sensors, providing a highly cost-effective solution for high-end industrial cameras, vision inspection, and scientific imaging.
I. Core Technological Breakthroughs: SenSWIR and Miniaturization
The IMX990 series is a groundbreaking product from Sony, utilizing a technology that stacks the InP (indium phosphide) layer and the InGaAs (indium gallium arsenide) absorption layer together via Cu-Cu bonding.
This means that the IMX990 not only maintains high sensitivity but also achieves a small pixel size of 5μm. Compared to traditional SWIR sensors, the IMX990 features a smaller 1/2-inch optical format at the same resolution, significantly reducing the cost of配套 lenses and enabling more compact camera designs.
II. Product Selection: Differences Between AABA-C and AABJ-C
The IMX990 series supplied by Mingjiada primarily offers two packaging options or specification suffixes, allowing customers to choose based on project requirements:
IMX990-AABA-C: PGA package with a thermal electric cooler (TEC), suitable for environments requiring extremely low dark current, such as long-exposure applications, scientific-grade imaging, and high-temperature industrial environments.
IMX990-AABJ-C: Ceramic LGA package (more compact), suitable for space-constrained embedded vision systems, UAV-mounted hyperspectral cameras, and portable inspection equipment.
Note: Mingjiada Electronics maintains stock of both specifications; actual availability is subject to inquiry.
III. Key Parameters: Wide Spectral Range and High Frame Rate
The IMX990 sensor has become the top choice for high-end vision systems due to its exceptional performance parameters:
Spectral range: 0.4μm to 1.7μm (visible light + SWIR).
This is the IMX990’s greatest advantage. It not only captures visible light in the 400–700 nm range but also detects short-wave infrared light in the 900–1700 nm range. This enables it to penetrate silicon materials, detect defects inside plastics and glass, and identify the chemical composition of objects.
Resolution and Frame Rate: Effective pixels: 1296 x 1032 (approx. 1.34 million pixels), supporting output speeds of up to 130 fps (8-bit).
Global Shutter: The sensor features a global shutter, enabling it to capture fast-moving objects without producing the jelly effect, making it perfectly suited for high-speed inspection on automated production lines.
Sensitivity: With a high sensitivity of 121 mV, it ensures excellent imaging performance even in low-light environments.
IV. Major Application Areas
Thanks to its dual-band (visible light + SWIR) capability in a single chip, the IMX990 is replacing traditional CCDs or single-band sensors in the following fields:
Semiconductor Inspection: Since silicon is transparent in wavelengths above 1200 nm, the IMX990 can be used to inspect wafer bonding, internal chip cracks, and through-silicon via (TSV) alignment.
Hyperspectral Imaging: Suitable for agricultural remote sensing (analyzing crop moisture/sugar content), plastic sorting (different plastics have unique spectral characteristics in the SWIR band), and pharmaceutical ingredient detection.
Laser beam analysis: Capable of imaging the spot shape and energy distribution of common infrared lasers such as 1064 nm and 1550 nm.
Surveillance and penetration: The SWIR band offers superior penetration through dense fog, smoke, or camouflage, making it suitable for security surveillance.
