IMX991 SWIR Image Sensor: The Top Choice for Industrial Inspection and Machine Vision Applications—Mingjiada Electronics Offers Long-Term, Abundant Stock Availability
I. IMX991 Product Overview
The IMX991 is a short-wave infrared (SWIR) image sensor from Sony Semiconductor Solutions Corporation’s SenSWIR™ series, designed specifically for industrial inspection, machine vision, and high-end imaging applications. Utilizing indium gallium arsenide (InGaAs) technology, this sensor captures images across a broad spectral range from visible light (400 nm) to short-wave infrared (1700 nm), overcoming the limitation of traditional SWIR sensors that support only a single wavelength band.
Equipped with Sony’s proprietary SenSWIR™ technology, the IMX991 successfully addresses the challenge of pixel miniaturization, achieving a compact sensor size and high resolution while maintaining high sensitivity. The sensor features a global shutter design, supports digital output, and incorporates built-in functions such as Trigger Mode and ROI (Region of Interest), making it ideally suited for industrial camera applications.
This sensor is available in multiple package versions:
IMX991-AABA-C: Ceramic LGA (with protective film) Includes
IMX991-AABJ-C: Ceramic LGA (with protective film) Excludes

III. Core Features
1. Wide Spectral Coverage (400 nm – 1700 nm)
The IMX991 is one of the world’s leading visible light + short-wave infrared (SWIR) dual-band imaging sensors. A single sensor covers a wide spectral range from visible light to SWIR. Traditional detection solutions typically require multiple cameras to cover the visible and SWIR bands separately, whereas the IMX991 achieves multi-band imaging with a single sensor, significantly reducing system costs and accelerating image processing.
2. SenSWIR™ Advanced Technology
Sony’s proprietary SenSWIR™ technology achieves a pixel size of 5 μm, enabling sensor miniaturization and high resolution while maintaining high sensitivity. This technology allows for the efficient integration of InGaAs photodiodes with silicon-based CMOS readout circuits, balancing performance and cost.
3. Global Shutter Design
The global shutter exposure method ensures that all pixels are exposed simultaneously, effectively eliminating rolling shutter artifacts when capturing moving objects and ensuring image clarity in high-speed motion scenarios.
4. High-Speed Imaging Performance
In full-pixel readout mode, 8-bit output reaches up to 258 fps, while 10-bit output reaches 240 fps. Using ROI (Region of Interest) mode, the frame rate can be further increased to over 486 fps, meeting the demands of high-speed industrial inspection.
5. Digital Output and Extensive Features
Unlike most SWIR sensors that only support analog output, the IMX991 supports digital output and features a built-in ADC, significantly simplifying the camera development process. It also supports advanced features required for industrial cameras, such as Trigger Mode.
6. Optional Thermelectric Cooling (TEC)
The AABA-C version features a built-in thermelectric cooling (TEC) element, which effectively reduces dark current noise and improves imaging quality in low-light environments. The AABJ-C version is an uncooled package, offering a good balance between performance and cost.
7. SLVS High-Speed Interface
It employs an SLVS (Scalable Low Voltage Signaling) output interface, supporting 2-channel or 4-channel configurations, ensuring the stability and reliability of high-speed data transmission.
IV. Typical Application Areas
Thanks to its exceptional features—including wide spectral response, high frame rates, and global shutter—the IMX991 is widely used in the following industrial and scientific research fields:
