The XLIN-FC-512 SQ is a 0.00-megapixel stacked CMOS image sensor manufactured by Xenics. It delivers a 512 × 1 pixel array with a 12.5 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 6.4 mm diagonal with a 21.33402778 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 12.5 µm pixels, the sensor features large pixels optimised for high sensitivity and dynamic range in low-light and scientific applications.
