HD/Full HD CMOS High Sensitivity Image Sensors for Industrial Applications

To improve sensitivity in the near infrared light region for industrial applications, Sony developed CMOS image sensors "IMX222LQJ", "IMX236LQJ", and "IMX238LQJ" for high picture quality at the low illumination, greatly exceeding the existing products. Newly developed process and pixel technologies pushed up the sensitivity in the near infrared light region, up to 2 times compared with the existing products "IMX122LQJ", "IMX136LQJ", and "IMX138LQJ".
For Day/Night cameras, which are also strongly demanded in recent years, better visibility improves surveillance performance, and fewer number of LED parts reduce the power consumption and cost.

Higher Sensitivity in the Near Infrared Light Region

High picture quality at the low illumination is strongly requested for industrial application cameras. Responding to this demand, Sony developed CMOS image sensors and improved sensitivity in the near infrared light region, not only in the visible light range. The CMOS image sensors used the technology from the EXview HAD CCDTM, and the sensitivity in the near infrared light region improved up to 2 times compared to the current products. This enables to identify objects clearly enough even in the night-time shooting. (Photograph 1)

Achieves Both High Sensitivity and High Resolution

Utilizing the Sony's original technology, the IMX222LQJ, IMX236LQJ, and IMX238LQJ were developed and achieved significant improvements in the sensitivity characteristics in the near infrared light region, as well as the high resolution and low crosstalk of the existing products.

Compatibility with Existing Sony Products

The IMX222LQJ, IMX236LQJ, and IMX238LQJ have the same image size, number of pixels, package, and pin configuration of the current Sony products: the IMX122LQJ, IMX136LQJ, and IMX138LQJ. Customers using the current products are easily able to replace with the new products. Please do not miss the chance to try the performance of the IMX222LQJ, IMX236LQJ, and IMX238LQJ.
