Sony IMX991 – 0.34 MP Global Shutter SWIR CMOS Sensor

The Sony IMX991-AABA-C is a compact CMOS image sensor designed for applications requiring high sensitivity across a wide range of wavelengths, from visible to short-wave infrared (SWIR). With a diagonal size of 4.1 mm (Type 1/4) and a resolution of 0.33 megapixels (656 x 520), this sensor is ideal for precision imaging tasks such as product sorting, semiconductor inspection, and remote observation.

This sensor features a global shutter with variable charge-integration time, which ensures accurate, distortion-free capture of fast-moving objects. The global shutter capability makes the IMX991-AABA-C especially useful in high-speed industrial environments where precision is key. Supporting frame rates up to 240 frames per second (fps), it is designed for real-time, high-speed applications.

The IMX991-AABA-C has wide waveband sensitivity, ranging from 0.4 µm to 1.7 µm, enabling it to capture both visible and SWIR wavelengths. This makes it highly versatile for specialized tasks such as foreign material inspection, temperature estimation, and semiconductor inspection. The ability to operate across such a broad spectrum enhances its use in advanced industrial settings where both visible and infrared imaging are necessary.

One of the standout features of the IMX991-AABA-C is its built-in thermoelectric cooling (TEC), which helps to minimize dark current and noise. This cooling feature ensures consistent performance in various operating conditions, particularly in low-light environments, where maintaining image quality is critical.
