On October 19, Canon released the 35mm full-size CMOS sensor “LI3030SAM (monochrome) / LI3030SAI (color / near infrared)” with improved sensitivity compared to conventional models by changing the pixel structure in late October 2020. Then announced.

By adopting 19 μm pixels, this product is capable of capturing monochrome movies even in a low-light environment of 0.0005 lux, and has tripled the sensitivity in the near-infrared region compared to conventional models. It is also possible to improve the visibility of video recording at night.

Furthermore, by allocating one pixel of the color filter as a pixel for the near-infrared region, even in a low-light environment of 0.001 lux, it is possible to simultaneously acquire color video and near-infrared video with one sensor, which was not possible with conventional models. Achieves a sensitivity improvement of about 2.3 times compared to conventional models in the infrared region. As a result, it will be possible to reduce the number of cameras and miniaturize the system in imaging systems and inspection devices.

In addition, since differences in the reflectance and absorption of light in the near-infrared region can be detected from weak signals and the internal state of the substance can be observed, nighttime monitoring, observation of crop growth, inspection of foreign matter in food factories, etc. It can be applied in a wide range of industrial and medical fields, such as visualization of in-vivo tissues.

The company explains that it can read 2160 x 1280 pixels, so it can be used for astronomical observation where wide-range imaging is required and for surveillance and industrial applications where there is a need for high-pixel images with a special aspect ratio.
